Jillian has been defending municipalities and their employees since 2013 and she has continued this practice with Marshall Dennehey, now leading the Cleveland office’s professional liability practice.  Although varied, Jillian’s public-sector liability practice focuses on police practices, sovereign immunity issues as well as labor and employment claims. Her employment practice extends to private employers, defending claims before the Ohio Civil Rights Commission, the EEOC, Ohio and federal courts regarding discrimination, harassment and retaliation, including claims brought pursuant to Title VII, the ADA, ADEA, the FMLA, trade secret litigation, whistleblower actions, housing discrimination and related tort claims.   

In her real estate work, Jillian has a strong track record of obtaining favorable results for real estate agents, real estate brokers, title agents, and home inspectors in cases brought against them related to alleged negligence, misrepresentation, disclosure errors, and contract disputes.  Jillian also concentrates her practice on D&O liability defending condominium and homeowners associations, as well as their directors, officers, and property managers, in matters involving alleged breaches of fiduciary duty, declaration disputes, real property document issues, and FHA, HUD and Fair Housing claims.  Additionally, she routinely defends insurance agents and brokers and miscellaneous professionals in matters pertaining to negligence, errors and omissions.  Jillian also has lived experience in non-profit D&O liability as a volunteer president of the board to a local community development corporation.

Further, Jillian’s practice extends to privacy and data breach matters, where she helps clients manage cyber risk and navigate incident response, containment, and compliance obligations. She also has experience defending corporate and individual insureds in product liability, construction, premises liability, and personal injury claims. 

A native of New York’s Finger Lakes region, Jillian earned her Bachelor’s Degree in Political Science from SUNY Albany. She received her juris doctor from Case Western Reserve University School of Law, where she launched her litigation career as an award winning student in the Criminal Defense Clinic. Before joining the firm in 2017, she gained valuable public sector experience as a judicial staff attorney and assistant director of law—skills she continues to draw upon in her advocacy for political subdivision clients.

Outside the office, Jillian can often be found enjoying live music or exploring the Cleveland MetroParks with her husband and their dogs.

    • Jillian’s Motion to Dismiss was affirmed on appeal after the Ninth District Court of Appeals found that Plaintiff had sued a non sui juris entity by suing a county department in a personal injury suit.  The Plaintiff initially filed suit against the department, and later dismissed without prejudice to allow more time to develop Plaintiff’s medical records.  When he refiled his suit, he again named a county department as the defendant.  Jillian filed a Motion to Dismiss arguing that a county department does not have the capacity to be sued.  Plaintiff then filed a Motion to Amend the Complaint and named the county.  Jillian then filed a Motion to Dismiss the Amended Complaint arguing that the plaintiff was outside of the statute of limitations and that the change in defendant could not relate back to the originally filed suit.  Plaintiff’s argument that naming the department was merely a misnomer and that the Amended Complaint should relate back to the original filing failed and the trial court dismissed the case.  After oral argument, the appellate court affirmed the decision.
    • In 2023, Jillian went to trial in a motor-vehicle accident case in which she represented a driver that had died while the case was pending.  There was also a large, financially successful, corporate co-defendant represented by other counsel.  The plaintiff had sustained a broken arm in the accident that was surgically repaired.  Jillian’s client had admitted liability, so the case was solely to be heard on the value of the injury, and the liability of the corporate co-defendant.  Likely counting on the deep pockets of the co-defendant, the Plaintiff’s pre-suit demand was not rationally related to the injury or in the realm of similar verdicts in the region.  During the first day of trial, Jillian formed a clear rapport with the jury panel, often engaging in friendly banter with the potential jurors about their own experiences in car accidents, injuries similar to the plaintiff’s, and the social impact of surgical scars.  This rapport was in direct contrast to a very dry voir dire by plaintiff’s counsel and was bolstered by a similarly friendly voir dire by the co-defendant’s counsel.  The parties completed their opening statements and returned to court in the morning, at which time the plaintiff asked to engage in settlement discussions.  As a result of Jillian’s trial performance, the case settlement for $1.5 Million less than the plaintiff’s demand the day before trial.

Successfully Defended a Suburban Mayor in a Defamation Case

We successfully defended an appeal of a trial court decision dismissing a defamation claim against a suburban mayor. The plaintiff, a former police officer, brought actions against a former city mayor and related defendants, asserting defamation, false light and related claims. The plaintiff alleged that statements made during a press conference disparaged him and violated a non-disparagement clause in his separation agreement. The court ruled the defamation and false light claims were correctly barred by the one-year statute of limitations under R.C. 2305.11(A) where the saving statute, R.C. 2305.19(A), permitted refiling in federal court, but did not toll limitations for subsequent state filings after the federal court dismissal. The appellate court also found the former mayor’s statements, regarding police leaders who allegedly retaliated against her, were deemed truthful and, thus, not defamatory or disparaging.   

Summary Judgment Won in Slip and Fall Case Involving a Large Supermarket Chain

We won summary judgment in Franklin County, Ohio, for a large supermarket chain in a slip-and-fall case. The plaintiff alleged he slipped and fell in the parking lot on ice that remained more than two days after the most recent snow fall and after the lot had been plowed and salted by a co-defendant. The plaintiff’s expert opined that no amount of remaining snow or ice is acceptable and that the standard of care according to the Ohio Building Code requires complete removal in order to maintain a “slip-resistant” surface. However, in Ohio, a premises owner is not liable for natural accumulations of snow and ice because persons are expected to appreciate the danger. The plaintiff’s expert did not opine as to what the defendants should have done, other than to completely remove the snow and ice. The court struck the plaintiff’s expert’s untested opinion as being unhelpful to a jury and found that the Ohio Building Code did not apply to the plaintiff’s pleadings without a claim for negligence per se. In disregarding the expert opinions, the court also found that the remaining snow and ice was “natural,” even though there had been attempted removal.

Aw Heck, As-Applied Challenges do not Implicate a Conviction

April 1, 2026

A new ruling from SCOTUS gives a lesson in Greek mythology, but more importantly makes it a near certainty that civil-rights plaintiffs will be able to run their malicious prosecution suit through summary judgment, despite a conviction. The oral argument led many to believe that the justices felt this was a complicated case, but in Olivier v. City of Brandon, a unanimous Court found that a suit that seeks prospective relief from arrest is not barred by the previous ruling in Heck v. Humphrey. Heck holds that a civil suit cannot invalidate a criminal conviction and is most often cited in cases arguing dismissal of a malicious prosecution claim because the plaintiff had been found guilty of the relevant charge. However, under Olivier, if the same plaintiff pleads prospective injunctive relief, the case may continue without an ad damnum request for damages. The result is an as-applied constitutional challenge of the law under which the plaintiff was convicted. There is no question that there is merit in reviewing the constitutionality of statutes and ordinances – but the as-applied challenge comes with significant expense and limited functional results. The Court even acknowledges that for Olivier to succeed in his suit for prospective relief, a court would find “something past should not have occurred” – that “something past” being a conviction in most cases. To come to this conclusion and avoid the implications of Heck, Justice Kagan drew a parallel to a citizen that seeks to enjoin enforcement of an ordinance that would prevent the plaintiff from exercising his free speech in the manner he desires – of course before the exercise actually occurs. There is no question that Heck does not apply in the case of a preliminary injunction, but Olivier presents an interesting glance into a criminal justice system that allows an accused to challenge the constitutionality during the criminal trial, get convicted, then challenge the constitutionality again in a civil suit. Practitioners should consider a request for prospective relief as an as-applied constitutional challenge that will likely need to be briefed at the summary judgment stage, therefore requiring discovery into the circumstances of the arrest.

Totality of the Circumstances: Tasing Okay in Immediate Passive Resistance

January 1, 2026

In a colorful opinion from the Sixth Circuit, the court found that it was not excessive force to tase the plaintiff when he refused to supply his hand for cuffing in the wake of more significant refusals to submit to the police officers’ authority. Feagin marks a return to the totality of the circumstances review, holding that there must be a comprehensive look at any relevant event that influences the use of force. The officers first encountered Mr. Feagin driving a Lincoln SUV, windows down, drinking liquor, smoking marijuana and driving down the middle of the street, causing the police vehicle to go into the ditch. There was a short pursuit before Mr. Feagin pulled over into a crowded supermarket parking lot, at which time the officers noticed the rear window appeared to be shot out. As the officers approached the vehicle, Mr. Feagin rolled up the windows. When an officer reached the driver’s side window, the SUV began to roll backwards. The officers banged on the windows, and the SUV stopped rolling. Mr. Feagin opened the driver’s door, and the officers grabbed his arm, causing him to limply lean out the door, at which time he began to resist and struggled to keep his body inside the driver’s compartment. During this struggle, bullets were falling from Mr. Feagin’s pockets. Once on the ground, the two officers tried to get Mr. Feagin cuffed, one officer attempt to grab his left arm, while the other had a partial hold on his torso. Mr. Feagin’s right arm remained free and flailing against the SUV. The officer holding Mr. Feagin’s torso tased him, allowing the officers to fully detain Mr. Feagin and place him in the rear of the police cruiser. Mr. Feagin alleged that the tase was excessive force, and the district court agreed, finding there was a question of fact, whether Mr. Feagin was actively or passively resisting at the time the taser was used. The Sixth Circuit reversed, holding that the entire encounter with Mr. Feagin should be considered, during which there were numerous times of active resistance. The Circuit Court also held that, even if the taser was utilized during the “twilight” between active and passive resistance, the doubt should be resolved in favor of the officer making split second decisions where the threat or degree of resistance is unclear. The court held: “We impose liability on individual officers only in the rare instance where an officer tases a suspect who posed no danger and was fully compliant with officer’s commands or had completely ceased resisting at the time of tasing.” A dissenting opinion (J. Clay) pressed for a more limited review of the case, finding that the argument was based in fact, as opposed to legal analysis. In assessing the Circuit Court’s duty, the majority opinion railed against the dissent to hold: "[T]he mere existence of ‘competing allegations on both sides’ does not stand in the way of us assessing whether legal arguments likewise exist. (***) We instead consider the facts in a light most favorable to the plaintiff. Any other approach risks eliminating our review altogether in this setting. After all, facts permeate every qualified immunity dispute. And qualified immunity exists to protect against a government official’s mistake of both fact and law. Those protections would be ‘effectively lost if’ an appeal were dismissed and a case ‘permitted to go to trial’ simply because a party highlighted factual disputes in the court of appeal. So rather than throwing up our hands whether the parties disagree over the facts or whenever the district court has assessed the record, we instead roll up our sleeves and train our attention on any remaining legal questions." (Internal citations omitted.) The Feagin opinion should be cited by every defense practitioner in a tasing case or in a case where it seems the fact questions should outweigh the legal analysis.

U.S. Supreme Court Decides Key Issue Regarding Interstate Freight Broker Liability

Freight brokers are intermediaries.  They connect shippers of goods with trucking companies that transport those goods.  Freight brokers match a load of freight with a trucking company and oversee the logistics of the transportation. For a number of years there has been a division among the Federal Circuits regarding the potential liability of freight brokers when the trucking companies that they retain for interstate loads are involved in accidents.  At the center of this division was the Federal Aviation Administration Authorization Act of 1994 (FAAAA).  Some Federal Circuit Courts have held that state law negligent hiring claims against freight brokers were preempted by the FAAAA .  Other Federal Circuits Courts have held that even if preemption applied, the “safety exception” in the FAAAA saved state law negligent hiring claims from federal preemption.  On May 14, 2026, the U.S. Supreme Court addressed the conflict in Montgomery v. Caribe Transport II, LLC, et al, No24-1238. In that case freight broker C.H. Robinson selected Caribe Transport to haul an interstate load. The commercial truck driver employed by Caribe Transport allegedly caused an accident and the plaintiff, Montgomery, was seriously injured. Montgomery brought an action against the driver, Caribe Transport and C.H. Robinson. The allegation against C.H. Robinson was that it negligently retained Caribe Transport when it knew, or should have known, that it was an unsafe company. The Seventh Circuit Court of Appeals held that Montgomery’s claims against C.H. Robinson were preempted by the FAAAA. The plaintiff appealed to the U.S. Supreme Court.  The U.S. Supreme Court’s decision focused primarily on the safety exception in the FAAAA.  That provision provides that the FAAAA preemption “…shall not restrict the safety regulatory authority of a State with respect to motor vehicles.” C.H. Robinson argued, as freight brokers historically have, that their function was not “with respect to motor vehicles” because they do not own trucks or employ drivers. They are merely intermediaries, connecting entities who need freight moved with entities who can do that job. Therefore, C.H. Robinson argued that preemption applied, not the safety exception. The U.S. Supreme Court did not accept that argument. The Court focused on the meaning of the phrase “with respect to” in the safety exception. The Court held that it means “referring to”, “concerning” or “regarding”. Therefore, writing for a unanimous Court, Justice Barrett concluded that “[r]equiring C.H. Robinson to exercise ordinary care in selecting a carrier therefore “concerns” motor vehicles—most obviously, the trucks that will transport the goods. So, Montgomery’s negligent-hiring claim falls within the FAAAA’s safety exception, which saves it from preemption.” Justice Kavanaugh, in his concurring opinion, noted the effect this ruling may have on freight brokers and their insurers throughout the country: Importantly, the Court's decision today should not be read to mean that brokers will routinely be subject to state tort liability in the wake of truck accidents. As even plaintiff's counsel stressed, brokers should be able to successfully defend against state tort suits if the brokers have acted reasonably and arranged transportation with reputable trucking companies. Tr. of Oral Arg. 27-29. In plaintiff's counsel's words, the brokers "just have to hire carriers that actually have a reasonable policy," and "the broker is not going to have a problem if it's asking the hard questions of the carrier." Id., at 42, 45. In addition, the proximate-cause requirement in typical state tort law should help protect brokers from excessive liability. Id., at 25. That said, the brokers rightly caution against naivete. In the real world, as the brokers forcefully respond, state tort law can be unpredictable, and the costs to brokers of litigation and insurance may be significant even when brokers prevail in lawsuits. Moreover, the costs of litigation and insurance, as well as the costs of brokers' conducting more substantial inquiries into trucking companies, will cascade through the economy and be paid in part by American consumers in the form of higher prices. The concerns expressed by the brokers are legitimate and weighty. The key point here is that freight brokers can no longer claim they are protected from negligent retention claims by the FAAAA (in cases involving interstate transportation). The challenge will be to determine what is considered ”reasonable efforts” used by brokers when retaining transportation companies.

No-Cause Jury Verdict Secured in Wrongful Death Trial

We successfully obtained a no-cause jury verdict in a 13-day wrongful death trial. The decedent, a 59-year-old man, was admitted to the emergency room on February 15, 2019, with complaints of abdominal pain, decreased appetite, and constipation, despite the use of laxatives. The patient did not complain of any nausea, vomiting, or diarrhea. He had a significant medical history including diabetes, hypertension, prior coronary artery stenting, morbid obesity (with past gastric bypass surgery), longstanding ventral hernia, and back pain. A CT scan revealed multiple hernias and a potential closed-loop bowel obstruction, leading to a surgery consultation. Our client, an emergency general surgeon, interpreted that the patient did not have a closed loop or any significant obstruction and recommended non-surgical management. The patient was approved to have clear liquids, and had a vomiting incident shortly after, but our client was not notified. The patient was returned to NPO status, and after improving overnight, he was returned to “clears” and additional medical and renal consults were ordered. Our client did not receive any communications from the residents/nurses of any changes in the patient’s condition. On February 18, 2019, two rapid responses were called due to increased heart rate and vomiting. It is believed that the vomiting resulted in aspiration, causing sepsis, ultimately leading to the patient’s death. During the trial, the plaintiff’s sole medical expert highlighted imaging on the wrong hernia, which called into question all of his opinions in the case. We made key objections related to the expert testimony, limiting what the allegations were, and preventing new allegations from being made. After approximately two and a half hours of deliberating, the jury returned a no-cause verdict.

PA Middle District Dismisses Claims Against School District and its Superintendent, Principal, Special Education Director, and Classroom Teacher

A five-year-old special education student was enrolled in the Wyoming Valley West School District and attended the State Street Elementary School during the 2024-2025 school year. The student refused to clean up classroom toys at dismissal. When his teacher allegedly grabbed him by the wrist to walk him back to his seat, the student dropped to the floor and began crying. The teacher then allegedly grabbed the student by the ankle and dragged him across the floor. Following an investigation, criminal charges were not advanced by the county DA, and the school permitted the teacher to return to the classroom. The student’s parents sued, lodging thirteen legal counts under both state and federal law, which sought monetary damages from the teacher, the school district, the superintendent, the principal, and the director of special education. The plaintiff’s 42 USC 1983 claims were dismissed as to the school district for failure to allege a policy or custom violation, and the failure to alleged deliberate indifference in the failure-to-train context. As to the superintendent, building principal, and special education director, the Section 1983 claims were also dismissed for failure to allege personal involvement on the part of the individuals. Regarding an equal protection claim asserted against all defendants, the motion to dismiss was also granted for a failure to advance a plausible equal protection claim, holding that “plaintiffs' single-act allegations do not include a factual basis to even infer that the act was motivated by discriminatory animus rather than some other non-discriminatory impulse.” The court further dismissed the plaintiff’s negligence-based claims including negligence against the teacher and district administrators, NIED, and vicarious liability under the Political Subdivision Tort Claims Act (PSTCA). The federal claims under the IDEA, Section 504, and the ADA were also dismissed in various respects. The IDEA claim was dismissed against all defendants with prejudice for failure to exhaust administrative remedies. The Section 504 claims against the individual defendants were also dismissed with prejudice, as districts, not individuals, are the recipients of federal funds under Section 504. However, the Section 504 and ADA claims were dismissed without prejudice as to defendant Wyoming Valley West, and the plaintiff was permitted leave to amend.
