  • 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.

He truly cares about his patients, explains everything in detail, and doesn't rush to make assumptions or give the typical "that's normal" response. [redacted] I'm glad to be one of his patients.
