Throughout our 50 plus years in practice in San Mateo, we have maintained a high standard of professionalism and competence promoting a close and loyal relationship with our clients. The needs of our clients are always our top priority which is why in 2016 we opened the additional office in Dublin to better serve the East Bay.

Our management team has been together many years and the principal manager is a second generation leader.

Some of our clients have been with us for two and even three generations.

We are very proud of the fact that throughout the years, we have experienced the "ups and downs" of the economy without reductions in client base or personnel.

Seideman Accounting Group has experience in many specialized fields, such as filing tax appeals, filing for private letter rulings, business valuations, and federal and state income tax representation just to name a few.

The firm's client base consists of a wide variety of businesses as well as individuals, demonstrating our breadth of knowledge and experience.
