Mary Ann Mancini's practice focuses on advising high net worth families and individuals who reside in the United States and internationally. Her clients include leaders of Fortune 100 companies and their families, as well as families whose wealth is more privately held and, in many cases, based on real estate ownership.
Mary Ann counsels her clients on all matters that affect their estates, including the structuring and formation of entities, the creation of irrevocable “dynasty” trusts, tax planning for families and the entities they own, and the protection and preservation of their assets.
Mary Ann is also experienced in succession and estate planning for closely-held business owners. She is a nationally recognized expert in techniques that utilize life insurance in estate and business plans, such as insurance trusts, split dollar and deferred compensation arrangements, and life settlements.
