Our Story

Cornerstone Accounting Group was founded by Margaret Chen, CPA, after years at a national firm left her wanting to build something more personal. She opened her first office on Main Avenue with one goal: treat every client's finances as carefully as she'd treat her own.

Today, our growing team serves businesses and individuals across La Plata County. We've grown, but the philosophy hasn't changed. Every return is reviewed twice. Every client has a direct line to their accountant. Every number matters.
