        Yes, I think Dr. Dimmitt is an excellent doctor and he explains things to you simply but doesn't condescend. He's very nice and he makes it easy to understand what he's talking about.

        Dr. Dimmitt is an incredible doctor. I saw him for the first time in February of 2025 and he most definitely saved my life. I wouldn't be here today if it weren't for him taking charge of my life. I owe him everything ??
