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.
i love Dr Parkman. I trust him with my health [...]
Dr. Parkman and his staff are incredibly impressive, highly trained and I have already referred several people to him.
Overall this was a good experience. Doctor Parkman was worth the wait.
Doctor put me at ease and inspired confidence.
Dr. Parkman has been treating me for 6 years and has always listened to my concerns. Discussed my treatment plan with me and treated me with respect and dignity.
Dr. Parkman listens to me when i talk to him about my condition. He is very attentive and focused on me. He is very thorough for the specialty service that he provides. I would definitely recommend him to others and I'm glad I've been referred to him as a patient.
Dr is very pleasant and did not rush me but when I am not feeling well and need advice, the on line msg doesn't seem to ever get a reponse as to what I can do when I am in a lot of pain.. I would like more advice between appointments if possible.
I constantly recommend Dr Parkman to anyone I encounter who has gastroparesis. He is so knowledgeable - even about a rare genetic mitochondrial disorder my geneticist is testing me for. He is the ONLY dr out of my several specialists who knew anything about it. He wasn't just aware, he was KNOWLEDGEABLE. If you ever need a patient to appear in a commercial for TUH, I am your woman. TUH is the best hospital. [...]
Excellent, thorough, and I love that he works with my sense of humor to break the ice & lighten the mood a bit!
I felt this provider, after seeing and analyzing my tests actually had a plan moving forward. He is - confident we can solve my health issues.
Dr Parkman is amazing. [...] he is empathetic, extremely knowledgeable in gastroparesis. driven to find the answers as to the why's of gastroparesis relating to my specific case, caring and excellent bed-side manners. He always listens to me and together we work to find out how my quality of life with gastroparesis can improve. That alone is so important to me.
He's brilliant and has ordered tests & Rx that have made my symptoms much better. He just doesn't listen well to my questions.
My present health issues are still being diagnosed so feel good that in the future they can find the cause and help me recover better than other physicians that have examined me!
I like my doctor - I can't recommend anyone go the office.
