About me

Even after more than ten years of practice, I still love what I do. My primary practice area is family law, and I have a special interest in helping business owners with family law issues.  I get to know my clients on a personal level, as I guide them through difficult decisions in their lives.  I also enjoy attending various bar association event and continuing legal education.
