His scheduler told me he was a very nice physician so I was hopeful I would have a good experience at my appt. And, I did! He was so kind and caring during the visit.

Dr. T was so patient as I hurried off to the restroom. He then helped me figure out that I may also need add'l treatment for things outside of the surgery clearance. I'm forever grateful!"
