    Dr. Tritos was great. The only potential "issue" was with technology. My primary care provider does not seem to be accessible in the Patient Gateway. I can see him, but I cannot message him. I have to go to his office's portal if I want to communicate with him electronically. He has my family medical history on record, but I am not sure if that is accessible to the other doctors in my patient portal (one of them being Dr. Tritos). I just wanted to bring that to your attention if it was not already known. Thank you.

And second, the people at the front desk and the nurses are exceptional and I definitely appreciate it and I don't take for granted the quality of care you have at your hospital. Thank you very, very much for having those people there to take care of patients like myself. Thank you. And thank you for the endocrinology that you have there. Thank you.

    I had gotten a bad MRI and went in upset with what I was facing and from the staff outside directing us in to the front desk, to the receiving nurse, to Dr Tritos and down to the blood taking nurse, our experience couldn't have been any better. Caring, knowledgable, wonderfully accommodating... It was a pleasure and hopefully a success. We left knowing that we got the best care possible. Thanks to everyone at MGH!!!
