having a bit of a personality and a smile would go a long way. encourage a patient to get better or get the help they need would be better than making one feel you are being scolded by your care provider.

No detailed explanation....just the standard here are your lab results, see you in a few months. It's like she has a flowchart and if the labs are x she does y and if the labs are b she does c. No exceptions, and all her patients are the SAME. She was rushed and not concerned about what my lab results actually meant.

This was my initial visit with Dr. St. John. She immediately put me at ease and was very relatable. I felt she was a good listener and explained her recommendations thoroughly. She took her time and was sure to ask if I had questions or concerns that we hadn't discussed. I am happy to have found her.

Dr. St. John is putting together a very complicated health problem that no one seems to be able to figure out. She called me at home with bloodwork findings and is messaging my pulmonologist. She was clear and not rushed with her explanations. she listened and answered my questions. I'm glad she is trying meds before completely removing my thyroid. I believe I have been blessed to have her and she will figure out or be instrumental in team working with my other health providers to determine if I have cancer or sarcoidosis. It has been a long 6 months of not knowing .
