Great suggestions
BBG is a pleasure to work with! We have Mary as our CPA and Guia as our bookkeeper. They are always quick to respond to any questions and are experts in the field, providing great suggestions along the way. I interact with Guia on a consistent basis, and it feels like she’s an internal employee! She and Mary retain details about our recordkeeping off memory, as BBG has been supporting our organization for over a decade! I would be lost without them. Thanks so much for the support!
