Requiring patients to review/enter information on a electronic tablet (the large orange tablets) was annoying and frustrating.

If it were not for Dr. Cannom, I would have given up a long time ago. However It appears that the administration is getting better than my past experiences.

Communication with the doctors is nothing like as easy as it was prior to joining PIH!!!

I really liked the fact that I was able to go get my treadmill stress test and then come over and see the doctor on the same day and he had the results from my test and Dr. Cannom is a wonderful doctor and I would highly recommend him to others and he's just listens to you and he's very caring and most of all he listens and explains things and is a very knowledgeable doctor as far as I'm concerned

I think the one that took care of me was very awesome, she's very friendly with me. She explains to me, things and you know, and on time

The wait time was too long. Our appointment was at 11:30 and we were not seen until 1:30 p.m. Waited 2 hours, which was too long.

The only complaint I have regarding my experience was that I had to wait over one hour past my scheduled appointment time.
May 26, 2021
For me the client the way they have treated me, I do not complain about anything, everything is correct. I thank you very much for you attentions. Goodbye bye.
May 25, 2021
Your new check in system is terrible! Being a Virgo, I hate to be late. It must've taken me 15 minutes to fill out the ridiculous check in process. I've been seeing Dr. Cannom for more than 10 years. If you must continue this please have the patient come at least 15 minutes early.
May 24, 2021
Dr Cannom is the best doctor and the best human being I have ever met. He is the most compassionate, caring, and smartest person. He has given me a new lease on life and I will be forever grateful to him. He is the best example of modesty while being brilliant beyond words in his field. He is one of my greatest gifts.

The use of the iPads is problematic. The questions that are asked have already been asked. This is the main problem and a reason to make me look for another provider. Please rethink the use of this cumbersome, repetitive, task.

Dr Cannom is absolutely first class in every conceivable way in treating one as a patient. Attentive in the extreme, he listens to your concerns, and explains all issues in a precise and comprehensible manner. I have been under his care for a great number of years, having had some serious cardiac problems, and throughout all difficult times, not only has his extraordinary expertise been so valued, but his gracious demeanor and kindly manner were always so evident, and appreciated. I could not speak more highly of him as both an outstanding practitioner in his field, and as a caring human being, totally devoted to his profession and indeed to those fortunate enough to be under his care.
