Very thorough and caring.
January 19, 2026
Dr. Kiriklakis is one of the best doctors I've ever had, and I should know, being 80 years old, I've had a lot of doctors. What I really like about him is his thoroughness. He takes his time, which Is why he's always running late (which I do NOT mind, since I'm retired.) Plus he's very affable and kind, doesn't criticize some of my choices (like other doctors have, especially about pot). My annual wellness visit with him is always a delight, not some heavy government necessity that I have to fulfill.
