About me

When I am not arguing with the IRS and negotiating fantastic deals for my clients, I enjoy spending time with my family - attending my kids' baseball games, seeing them develop their musical/artistic talents, seeing them grow into responsible (hopefully) adults. 


I grew up in the Central Valley "one-high-school town" of Ceres.  I spent 4 years in Southern California while I attended college, and we have lived in in the greater Sacramento area since 2000.


I enjoy cooking (ok, mostly eating) and reading a variety of books.  I love listening to music.  I have moved beyond 1980s heavy metal bands of my youth, but not too far beyond:)
