O’D&D CPA’s has again done a job with my business taxes this year. In particular, Sheri and Louise are exemplary in maintaining high professional standards and always striving for quick response and quality client services - they never miss a deadline or leave any questions unresolved!

Thank you for your excellent support.

Our Morgan Stanley wealth advisor recommended Sam Dennis and his practice to us, and we are very pleased with and grateful for their excellent service. We needed help navigating our recent retirements, filing for solar and HVAC improvement rebates, and complicated out-of-state taxes from my father-in-law’s estate and sale of his residence. O’Donnell and Dennis CPAs guided us through flawlessly and without stress, and we have high trust in their expertise on these varied matters. Sheri at the front desk is helpful and responsive. We appreciate that Sam spent time to get to know us prior to engaging with us, including a second meeting with our wealth advisor present.… read full review

My wife in I got in to meet Sam for an initial meeting very quickly and we were extremely pleased! The office space was warm and inviting and well put together. We were very impressed with Sam's demeanor, as he was calm and cool. We were so grateful that Sam answered many of our questions with expediency and accurate knowledge. We are a small business that is looking for financial and tax help, and we found a great place to go! I would highly recommend O'Donnel & Dennis to anyone who is confused about the complexities of small business financing and taxes!
