Clients have entrusted some of their most difficult and technologically sophisticated cases to Tim and his team.

Prior to joining Verrill, Tim practiced in the #1-ranked IP litigation practice group at WilmerHale. While there and since, Tim has handled patent cases involving a wide range of technologies including software, data and telecommunications, online banking, computerized mammogram screening, controlled fluid delivery in medical devices, spinal fixation, and blood glucose testing.

When not practicing law, Tim is active in local, state, and federal politics. He is a former member of both the Hillary for Maine Finance Committee and the Obama for Maine Finance Committee. He is Chairman of the Yarmouth Town Democratic Committee. He is President-Elect of the Federal Bar Association of Maine, and—most important—a devoted husband and father of three fantastic kids.
