About me

My practice emphasizes estate planning (Wills, Trusts, Tax planning, Powers of Attorney and Health Care Directives); probate; real estate and business. The most enjoyable parts of the practice of law for me are the opportunties to get to know the many interesting people I meet, work with them to solve their legal situations and problems and help them plan their personal and business legal matters.
The best way to reach me is to call me at (425) 454-5829.
