Our story
Diane Whitfield founded Summit in 1998 after twelve years inside Big Four audit teams. The reason was simple: small business owners were getting the same boilerplate advice as Fortune 500s. Today, Summit is a six-person practice serving 240 owner-operated businesses across Colorado and Wyoming. We answer the phone. We explain the numbers. We file on time, every year, since 1998.
