Dr Carroll is an awesome physician. Dr Carroll is concerned with my overall medical conditions. He takes the time to make sure you’re up to date on your vaccines and preventative exams. My labs showed an improvement with the help of Dr Carroll care.

Dr Carroll is an excellent physician and a superior diagnostician. He doesn’t miss anything, even though I have a complex array of conditions. He keeps track of my multiple sub- specialists and medications and contacts my other physicians when coordination of care is needed.

He listened to the explanation and did appropriate testing. He also made sure the upcoming MRI would address concerns about the eye socket.
