Gregory P. Graham


    Greg is a member of the Professional Liability Department whose practice focuses on the defense of corporations and professionals in commercial, construction and class action litigation. He also defends attorneys in legal liability actions covering a wide range of malpractice claims including those arising from civil and family disputes, business transactions in the real estate and oil and gas industries, and commercial litigation. 

    Greg has substantial experience defending high-value class action cases at both the state and federal level.  In doing so, he prioritizes the development of an early case strategy to defeat class certification in order to minimize his clients’ potential liability and damage exposure. He has successfully defeated class certification in multiple jurisdictions for clients facings claims of invasion of privacy, violations of state and federal electronic communication protection acts, and allegations of improper assessment and conversion of state sales taxes. When certification cannot be avoided, Greg develops an aggressive discovery strategy to minimize class size and damage exposure. He has obtained summary judgment dismissals and favorable settlements in class actions in both state and federal court.  

    Greg's construction practice includes the representation of owners, contractors, and design professionals from defect and commercial loss claims related to the construction industry. He has litigated on behalf of clients in matters arising from publicly and privately-funded projects in state and federal court across the country. He also defends construction entities in the natural gas and energy industry facing high-exposure commercial loss and environmental claims. 

    Greg has experience litigating on behalf of securities professionals in court and FINRA arbitration. He has successfully assisted financial management companies in responding to administrative investigations brought by state and industry regulatory agencies.  

    He is also proficient in matters involving significant E-Discovery and document discovery.  His experience with managing large-scale E-discovery efforts minimizes unnecessary cost while also allowing Marshall Dennehey to provide the best defense possible for its clients in discovery-intensive cases.    

    Greg was a 2013 graduate of the University of Pittsburgh School of Law. While in law school, Greg was invited to be a visiting research fellow at the Max Planck Institute for Comparative and International Private Law in Hamburg, Germany.
