In my entire "diabetic" career of 37.5 years, I have seen 3 endos, the first 2 were pediatric endos from when I was a kid. The next endo was recommended by my primary care doctor. At the time he was young, probably recently out of medical school, and was generally ok, not very informative, but I didn't ask a lot of questions either. I needed him for prescriptions but beyond that I used my primary care doctor. Fast forward 20 years and a few really severe hypos from humalog overdoses, and I knew I had to change. There are 2 doctors that work in the Joslin clinic in Needham, MA and 1 nurse practioner, and 1 CDE. I had developed a really good working relationship with the CDE and asked her opinion about my new endo. Her response was "her patients seems to like her and she seems to spend more time with them, but I have worked with Dr. S for over 20 years and I have only worked with her for 3 years, but if you switch you cannot go back to Dr. S." I replied that in the 20+ years I had been his patient, I had never really made much of a connection with Dr. S and as I approach menopause I felt I would be far more comfortable working with a female doctor. So I made the switch. I am very happy I did. I wish you good luck, finding an endo who will listen, explain, allow questions, and respond because it is incredibly important.
