The Firm


We help you remove uncertainty from your finances with guidance you can trust.

In 1980, Marcus E. Ullrich established his accounting firm in Woodland, CA, and Anthony J. Delevati joined the team the next year. Within a decade, they partnered to create Ullrich Delevati CPAs, and together, they set out to grow a practice that would serve and bolster their community.

In the years that followed, we grew from a small partnership to a full-service accounting firm, helping individuals and businesses not just in our immediate community, but beyond in the greater Northern California area and bordering states. In 1995, we added Jim Engstrom as a Principal for our West Sacramento Office.

As our firm grew through the new millennium, so did the dynamics of our team. And in 2020, Mark passed the baton of Managing Partner to Tony while the firm added Senior Accountants Lisa Martinez Dunham and Vivian Plank to the team Partners.

And today, our four Partners, our Principal, and our talented team of accounting professionals and support staff, allows us to bring our clients well-rounded financial expertise, sound business advice, and personalized tax planning services that help them gain clarity and experience the bright financial future they deserve.
