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.

An exceptional working relationship. I have been working with Susan Lewis, CPA for more than 20 years. She has provided excellent business and personal tax services, as well as small business advice. She and her staff are professional, knowledgeable, and responsive, and over the years, Susan's advice has been invaluable. I have given her name to clients, friends, and family members, all of whom report a high degree of satisfaction with her work. Without hesitation, I would give her the highest rating.
