“I’m passionate about building relationships.”

I joined Johanson & Yau in 1980 and became a partner in 1986. I direct the firm’s business strategy and operations including client service, practice/business development, finance, human resources and IT.

I represent a wide variety of businesses and individuals and provide accounting, tax planning and general business consulting services to executives and owner-managed businesses.

My wife and I live in Willow Glen. In my free time, you can find me catching up with my daughters and friends, and enjoying an occasional golf game.
