Some things never change.

Locally owned and operated in Yakima, Washington, Petersen CPAs and Advisors is a certified public accounting firm providing highly personalized tax, audit and accounting services to businesses and individuals.

A little history

Our firm originated in 1953 when Robert R. Dolsen opened his own CPA practice. Over the years as the firm changed ownership, so did the name, and in 1987 we became known as Martin, Holland & Petersen, PLLC. After Martin and Holland retired, Ryan Smith and Abby Sanders joined remaining partner, Mathew Petersen, and a new season of ownership began.

The heart of our practice

However, while our name has changed, one thing has remained the same: our focus on friendly service and expertise. Because at Petersen we know when it comes to delivering value, what really matters to clients isn’t the name on the sign; it’s the personalities of our people. For more than 50 years, the heart of our practice has been the relationship we develop with each client. Because few partnerships are more personal, we value the qualities that nurture trust and respect:

  • We return calls quickly
  • We are readily available
  • You work directly with experienced, seasoned staff
