Dr G was great. Honestly. It is often a crapshoot if your provider will have good bedside manner. Sometimes you have to trade off good bedside manner for skilled care. He had both. He took the time to explain everything to me. He asked questions AND listened to the answers. Very personable. 10/10 stars. Big fan here
