Very kind and thorough. Very willing to answer questions. Happy we got in to see him today!
It was refreshing to see an actual doctor instead of PA or NP, seemed to actually want to correct the problem versus “putting a bandaid on it”l I appreciate that!
Explained treatment and other Options if needed. Very Thorough.
