Serving as chair of the firm's Eminent Domain/Valuation Litigation Group, Mr. Hennessey has more than 45 years of total legal experience and 35 years of experience in eminent domain litigation. Over the course of his practice, he has successfully handled almost 500 inverse condemnation matters for a wide range of clients, including businesses and corporations, individual property owners, and other key stakeholders.

During the course of his legal career, Mr. Hennessey has gained a reputation as a leader in eminent domain and inverse condemnation law, and he also handles valuation litigation and lease renewal valuations. He received a published decision in a case involving contaminated property in the eminent domain context, which was the state's first appellate opinion regarding this type of case.

He has also secured many other multimillion-dollar judgments and awards for his clients.

After graduating with distinction from the University of California, Berkeley, in 1975, Mr. Hennessey attended the University of San Diego School of Law, where he obtained his Juris Doctor in 1978. The State Bar of California admitted him to practice that same year, and he has served on the organization's committee on condemnation law. He is also an active member of the Orange County and American Bar Associations, the Condemnation Attorneys Group, and the International Right of Way Association, among his other professional affiliations.

A leader in his field, Mr. Hennessey has conducted lectures and continuing legal education seminars before the Appraisal Institute, the International Right of Way Association and CLE International on topics involving eminent domain, valuations and other subjects.
