Cullen is an associate in the firm’s Private Wealth Services practice. He advises clients in all aspects of charitable, tax, business succession and estate planning. He previously practiced at a Tennessee-based law firm, where he developed and implemented tax-advantaged generational wealth transfer and business succession plans for ultra-high net worth clients.

While skilled in the mathematical aspects of planning, Cullen understands that a good plan is ultimately defined not by the numbers involved, but by the peace of mind and security it provides the client. To that end, Cullen strives to create personal relationships with clients that embody trust and confidence.

A frequent presenter and publisher on estate planning topics, Cullen is also active in both the Tax and the Real Property, Probate and Trust Law sections of the Florida Bar. He currently serves as an adjunct professor in Estate Planning at Stetson University College of Law. Cullen is barred in Tennessee and continues to serve clients with Tennessee-specific issues.
