Treatment Philosophy
My approach to patient care includes obtaining a careful patient history of the symptoms, obtaining carefully selected tests to evaluate the patient's symptoms, reviewing the results of the tests with the patient and deciding on the appropriate treatment for the symptoms and disorder together.
Dr. Parkman is a very caring and empathetic doctor.
This was a telemedicine visit, so [...] I did not have an opportunity to meet Dr. Parkman face-to-face, but our conversation over the telephone was very helpful. I'm looking forward to beginning treatment with him.
I LOVE Dr. Parkman and his staff. He is the best doctor I have ever seen and the comfort he brings with his expertise on gastroparesis is invaluable. I trust him with my health care and he listens to my needs and provides workable solutions. His bedside manner is impeccable and it is very clear that he cares about his patients. I cannot stop singing his praises for his help with my rare disease where other doctors had failed me.
My experience was wonderful [...].
i really like Dr. Parkman he really helped me a lot
because dr. Parkman is such a specialist in gastric paresis seeing him is the only option I have although I don't always get callbacks about concerns that I have during regular business hours things do eventually get worked out but he is very busy because of him specializing in gastroparesis the clinic is only one in five in the country that understands gastroparesis patients
The receptionist etc. are great. Dr. Parkman is great. [...]
[...] The woman that checked me in was very nice and polite and Dr. Parkman is wonderful. If I didn't love seeing him and if I didn't have the device I wouldn't come back to the facility, the other office staff is very rude.
[...] he is the only doctor that has helped w/my quality of life.
this was my first visit to Temple and Dr Parkman. [...] the visit was excellent. Everyone from valet to Dr Parkman was professional and friendly putting me at ease. [...]
I had a very positive experience with dr Parkman.
