Bellingham-based accounting firm Larson Gross has made a top-level executive change.

Aaron Brown has been promoted to CEO of the company, and previous chief executive Marv Tjoelker is now chairman of the board and spokesman for Larson Gross’ nine-member ownership group.

The transition is designed to give Tjoelker more opportunities to work directly with clients, particularly in the areas of business succession and financial planning, according to a company news release.

Brown has been with Larson Gross since 2003. Prior to his promotion to CEO, he served as the company’s chief operating officer. He has also held positions of marketing director and operations director.

Larson Gross has offices in Bellingham, Lynden and Burlington.
