Client Reviews
I have had a fantastic experience with Sue Lewis as well as the other wonderful women in the office. They have helped guide me through my personal and business taxes in addition to corporate debacles that I faced before finding Sue. My friend recommended me to Susan Lewis and I have recommended her to others. Between communication, follow-up, persistence with tax issues and professionalism, you really can't do better.
