Dan Bettelon

Dan, who was born and raised in Michigan, transplanted to the Bay Area in 1982. He graduated with a bachelor's degree in business administration from San Jose State University in 1986. Immediately thereafter, he began his career in public accounting with Wellings, Tull & Co. in Menlo Park. Working under the tutelage of Sarah Tull, he became a Certified Public Accountant in 1991. Dan joined Sarah when she opened her own business in Palo Alto in 1992 where he worked up until October 2011. Dan is proud and excited to join with Linh Duong in opening their new CPA practice.

Dan and his husband Victor live in San Francisco with their three miniature pinschers Noodles, Bruno and Chico. They've been fortunate to have traveled to many locations throughout the world, but always find themselves returning to Paris which they consider their home away from home.

Linh Duong

When I took my first accounting class in college I knew exactly what my career path would be. Before starting Bettelon, Duong & Parrish LLP, an accounting and tax firm in Palo Alto, I had worked at several local CPA firms and hi-tech start- up companies in the bay area where I gained valuable experience in the area of accounting, tax and finance.

What I value the most in my career as a CPA is the relationship that I have developed with my clients over the years. I thoroughly enjoyed assisting them with proper planning which enabled them to make the right financial decision. I also tried to navigate them through our complex tax law and helped them solve their unique tax issues and prepared their tax returns. My clientele consist of individuals with domestic or international tax issues, trusts, estate and small businesses, including hi-tech start-ups. To be able to take the worries off our clients' minds relating to tax matters is my goal.

Besides playing with the numbers and the tax code, I also like to paint and draw and enjoy swimming. I am married and have 3 children.
