  2. Firm


We are a locally owned firm deeply rooted in the Spokane, Washington area and have many long-standing connections on our community. You can count on us to put our skills and our understanding of the local business climate to work for you, ensuring the highest level of customer service and satisfaction.


Our firm started out in the early 1980s as Heiskell & MacGillivray, when our founders, Doug Heiskell and Andy MacGillivray first hung out their shingle. Over the years, the ownership changed, and, since clients had a tough time spelling it anyway, in 2015 we updated our name to HMA CPA, PS. In recent years, we acquired four other existing firms: Engel & Associates, Dorendorf & Associates, Michael D. Caprye, CPA and Kavadias Group PLLC, bringing even greater strength and diversity to the skill set and experience of our staff. In December 2022, Eva M Weisenburger CPA PC was merged into HMA CPA, PS adding lines of service and amazing staff to better serve our clients. To acccomodate our expanding services, HMA moved to a larger location at 601 W 1st Avenue. There is more space to spread out and meet with our clients, and for our HMA staff to be a strong and cohesive team. HMA’s current owners are Kevin Sell, Laura Hays, Mike Whitmore and Kristi Bushnell.
