Estate Planning
Jay handled our family consultation very professionally. Everyone's questions were answered completely so the family could make complex decisions with ease. We are grateful to Jay for his expertise and timely approach in addressing some long running family concerns. The result is piece of mind by completing a comprehensive estate plan, health directive, a trust and naming the trust administrator. Thank you Jay.
