Jeffrey T. Antonchuk


Jeff is a partner in the firm’s family wealth practice. He chose this area of the law before he entered law school thanks to his personal experience with a poorly drafted and implemented estate plan for his grandparents. Those circumstances motivated him to implement high quality estate plans and treat clients like family. Jeff takes pride in having been a trusts and estates attorney his entire legal career because it allows him to help his clients with wealth preservation, family harmony, and security.

Jeff is a writer and speaker for estate planning groups. When he’s not helping other families, he’s spending time with his own or going on adventures like backpacking through Central America and summiting Mount Shasta.
