Mitzi McMullen is the best bookkeeper I have had in over 20 years! She is prompt, efficient, accurate, honest, and friendly.  Her casual, yet professional demeanor is perfect for a small office environment, and her willingness to research, answer questions, and follow up on outstanding issues with both vendors and clients is especially valuable.  For more than 7 years she has overseen the books for both non-profit and for-profit entities in our office, providing indispensable continuity, confidence, and reliability.  I highly recommend her!”

Mitzi was a lifesaver when I was going through a very difficult transition time with my business. Her calm professionalism was exactly what was needed. I breathed a sigh of relief after our first meeting, feeling immediately that it would all work out. She has a way of homing in very clearly on the essentials and was able very quickly to come up with a plan to tackle what felt to me like a disaster. She is personable and a very effective communicator. I can't begin to thank her enough for her help.”
