Dr. St. John listens to me and, I feel, she gives me her honest opinion based on her knowledge and experience. She lets me know if I can do better, she lets me know if I need to be more honest with (am lying to) myself (and thus her), and I need and appreciate that.

Dr did not recall my situation. I've been a patient for years now, but she did not understand my situation. i had to explain it a n d even then I'm not sure she understood or agreed. She had my prior Dr's notes but did not recall even though I see her every 6 months. I really need my Dr to know who I am instead of typing everything i say into a laptop. Disappointed me...

Unsure of what she's doing when the patient's labs don't fit into her flowchart, ie, numbers go up decrease meds, numbers go down, increase meds. Very disconcerting. Gets defensive when you want to include other physicians in your plan of care. I AM the patient, it's MY decision and MY health that's involved, NOT HERS.

Dr St. John has a great personality and seems to care about her patients. she has even stepped up and compensated for my pcp's shortfalls of providing care for another chronic condition. The office also works like a well oil machine to make sure patients are in and out in a seamless manner.

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.
