About me

My practice exclusively focuses on helping families plan for the future and administering the estates of their loved ones. Unlike other attorneys, who offer estate planning and administration services as part of a general practice or big firm, I have developed the depth of experience and skill that comes with concentrating on one area of the law for decades.

I serve a wide range of clients, some who have amassed considerable wealth and others with more modest means. Many clients come to me with complex family arrangements while others have simpler, more traditional needs. I take pride in confidently serving all of them with equal attention. 

I charge clients for my services on a flat-fee basis.  Other lawyers charge by the hour and have clients who leave their offices feeling unnerved about the ultimate costs of legal services.  I believe that uncertainty breeds dissatisfaction. 

That is why, after an initial meeting to determine a prospective client's needs, I quote a fee to complete the work that needs to be done. If a prospective client chooses not to proceed, there is no charge for the initial meeting. If a client does ask me to proceed, the client knows exactly how much my services will cost before making a commitment. I charge no additional fees when my clients have additional questions about their estate plans, even years down the road.
