Attorney Hayne Barnwell has provided fierce and intelligent representation protecting the constitutional rights of her clients since she was admitted to the Massachusetts Bar in 2006.

She has honed her skills throughout her work for prominent criminal defense/appeals law firms in Boston and Cambridge. She now focuses her practice on appeals, both civil and criminal, and criminal defense, in state and federal courts throughout Massachusetts.
