Reviews From Our Satisfied Patients

  • ""Being new to Vermont, I wasn't sure which optometry practice was best for me. I landed at the office of Thomas H. Clark OD after a terrible experience at another optometry office nearby. Dr. Clark and his team have proven to be just what I was looking for. Dr. Clark is an excellent eye doctor and his team provides exemplary service. They offer a good selection of products and their lab turns out excellent high quality lenses that offer the clearest vision correction I have ever had in glasses. Their knowledge, ability, care and professionalism is superior to others that I have found. If you seek vision correction that is spot on, and you value high quality patient care, I recommend a visit to this office in Williston, VT.""
