Dr Thomas is the best doctor I've ever had. He has saved me from several negative issues and fixes then immediately. 1 being when my neurologist said I don't need a EMG for carpel tunnel because you have a blood flow problem. He went around the neurologist and had the EMG done. I did have a severe case of carpel tunnel and 2 when I was hit by a falling branch and the ER missed the branch that was in my arm and he sent me back in for another ultrasound and discovered I had a piece of the branch still in my arm. You can't be any more thorough than that. And you can't make this up, it's all in MyChart. I'm blessed to have Dr Thomas as my primary care provider.
