About Thomas Henry Merrill, MD

Care Philosophy I am passionate about the Norman community, and I'm thankful for the opportunity to take care of my neighbors. My hope is that my patients feel like I understood them, that all their needs were addressed and that I treated them like my own family.

      Highlights from patients about their experience with this provider:

        (5/5)
        Dr. Merrill is the best!
      • May 27, 2025
        (5/5)
        As always, Dr. Merrill and his assistants are the best professionals in this area. He is a "one of a kind" doctor and no one will be able to replace him. Mercy should try to clone him, or at least pay him to remain a consultant when he retires. He understands what "medicine" means.

        Dr Merrill is the best doctor I have ever been with
