MacKenzie represents corporations and individuals in their fiduciary capacities (i.e., trustee, executor, administrator, guardian, agent under powers of attorney) as well as estate and trust beneficiaries in matters involving claims of breach of fiduciary duty, undue influence, lack of capacity, fraud, duress, and negligence.
