I am a fee-only NAPFA registered Certified Financial Planner ™ and U.S. Treasury Enrolled Agent. I am currently working toward my Chartered Special Needs Consultant® (ChSNC®) designation. I help clients organize and gain control over the many parts of their financial lives. This helps the client to focus on the important aspects of their personal lives, both in the present and in the future. My planning places a strong emphasis on the simultaneous reduction of investment costs as well as taxes.
I work with individuals and families at all levels of income and wealth. I specialize in helping special needs families and those facing aging-related challenges. Creating a special needs financial plan reduces the financial burden and allows the loved one to live a full life.
