Our first move to Northern California came in November 2017 through a merger in Campbell, California.

Ever since then, we are proudly serving the Silicon Valley area as a reliable and hardworking CPA firm. We are comprised of highly technical and experienced tax and audit professionals led in this Silicon Valley CPA office by Managing Partner Howard Loomis.

We provide comprehensive tax, audit, consulting and wealth management solutions – as well as a variety of highly specialized services – to our clients. Our wide range of skill allows us to serve clients of all sizes, as we have worked with start-ups to multi-billion dollar companies, as well as high net worth individuals.

Squar Milner was recently named one of the fastest growing accounting firms in the country, a Top 5 CPA firm on the West Coast, and a Top 40 CPA firm in the United States. We worked hard to get here.
