This was my first appointment with Dr. Carroll. I really appreciated his patience and respectful manner. I have a very complex medical history and multiple complex medical issues and believe Dr. Carroll will be able to optimize my health and quality of life. I was very relieved that Dr. Carroll has such a nice bedside manner.

when training medical students it's nice to have them but as a patient I don't plan for extra time to spend with them unexpectedly. otherwise I am very happy with my provider.

Dr Carroll is my Endocronologist. he is professional, caring, and explains all of my health issues to me. I have recommended him to other diabetics I know. before I saw Dr Carroll I was injecting insulin 5 times a day. 5 years ago, he changed the injections and put me on a better regiment of care for me. he is an outstanding doctor

Took time to explain everything very well (I appreciated him explaining to me the things that could potentially be causing my issues and why were testing what we were- he kind of walked through his problem-solving process with me instead of just explaining diagnosis at the end), addressed my concerns, and was really good at communicating. Incredible doctor!

Dr Carroll, has the best bed side manor that I have in countered in a long time. He made you feel like you where very important. He took time to explain everything including going over the ultra sound that was done. The medical field needs more Doctors like him. At least I didn't have to be in and out in 15 minutes.

He read up on my medical history and took the time to talk to me about how I was feeling. He never made me feel rushed or like I was crazy for naming my symptoms. He also took time to explain things to me and wanted to make sure I understood what was going on. He was beyond excellent. I have been feeling hopeless and after seeing him, I finally have some hope!
Feb. 21, 2019
very thorough.
Feb. 18, 2019
For the first time EVER, a doctor (Dr. Carroll) actually reviewed my medical history with me. With me being a new patient, that would mean that he reviewed my records that I transferred over. We were impressed and grateful for that! He also examined me and listed to what I was saying. He provided me with thee best care I have received in years. He also got back to me within 24 hours with my lab reports. Overall a top notch doctor!
Feb. 15, 2019
Dr. Carrol is extremely knowledgeable and kind. He is my endocrinologist and I could not ask for anything better. Switching from my last provided to him was one of the best moves I've ever made. I would recommend him in a heartbeat to anybody. I only wish all medical providers could be as great as he is. Hands down. His Nurse that travels with him is also wonderful. Thanks for the great service Dr. Carrol and team!
