Derek began his legal career working on a wide range of transactional and litigation matters, including trusts and estate planning, business transactions and litigation, general commercial litigation, and commercial and residential real estate transactions and litigation. As time passed, Derek realized his passion lay in the transactional practice areas of trust and estate planning and administration, corporate law, real estate, and other related areas in which he currently serves his individual and business owner clients.
