I have been his patient for many years and always have found him to be the BEST. He has taken great care of me and when biopsies are needed, I am not concerned because I know from past experience how amazing he is to keep them painless. He is great at communicating all information I need and tells me when to see him again and to call him if any questions should arise. Excellent Doctor.

Dr. Alexander is a very responsive and caring and extremely qualified clinician. I had a concern about my thyroid, a little nervous that I was having more cancer going on and he immediately arranged to see me and saw me in an extremely timely manner and was very, very reassuring. So I am so grateful that the Brigham has done such a fabulous hire and appreciates the expertise of Dr. Alexander so that he will stay on the staff of the Brigham because I think he is just an absolutely superb doctor and a wonderful, wonderful person, caring, far beyond medicine, just a very, very supportive human being and I really appreciate the fact that I can be the patient of a doctor like him. So thank you very much.
