William G. Roark is a Principal of Hamburg, Rubin, Mullin, Maxwell & Lupin and chair of the firm’s medical marijuana practice. He represents individuals and businesses in the medical marijuana industry by helping them comply with Pennsylvania’s Medical Marijuana Act. He assists clients to understand the permitting application process and the requirements associated with entering this industry.  Because he has remained on the forefront of the legislative development and implementation of the Act, Mr. Roark has been asked to plan and present at various educational seminars teaching other professionals about this new law.  Since 2014, he has devoted his time to expanding the legal profession’s knowledge and awareness of the Medical Marijuana Act and its precursors so that the profession can be better prepared to meet the numerous legal needs on the horizon. He currently serves as co-chair of the Pennsylvania Bar Association’s Medical Marijuana and Hemp Law Committee.

A member of the firm’s Litigation Department, Mr. Roark’s practice also includes environmental litigation and catastrophic injury cases. His clients have included individuals suffering from traumatic brain injuries, medical malpractice and exposure to dangerous chemicals.

Mr. Roark is an active member of the Montgomery Bar Association, chairing and participating in various committees. Mr. Roark is a past editor for the Montgomery County Law Reporter, past chair of the Environmental Law Committee and a contributing editor to Montgomery County’s Civil Practice Manual. He serves as a member of the Board of Directors of Legal Aid of Southeastern Pennsylvania. In 2016, Mr. Roark was selected to participate in Montgomery County’s prestigious Leadership Academy.

A graduate of Bucknell University (B.A. Economics, cum laude, 2003), Mr. Roark received his law degree with honors in 2006 from Villanova University where he served as a member of the Villanova Moot Court Board Executive Committee. Prior to joining the firm, Mr. Roark worked for Environmental Equipment Inc., where he helped usher in the green-age by selling, servicing and installing solar pool heating systems.

For eight consecutive years (2010-2017) Mr. Roark has been selected for inclusion in Super Lawyers – Rising Stars Edition. No more than 2.5 percent of the lawyers in the state who are 40 or younger, or who have been practicing for ten years or less, are named to the list each year.
