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 was referred to Dr. Parkman by Dr. Forde. I detest being sick, going to the doctor-it gives me anxiety and have been dealing with this Issue for the past 2 years. Dr. Parkman has given me hope and answers. Words cannot express how I feel having met him and know there is finally light at the end of the tunnel. I am not out of the words just yet but I see a glimmer and I am so happy. He is patient, beyond knowledgeable, and caring.
Dr. Henry Parkman is an exceptional person and physician. He has improved the life of patients suffering from gastroparesis in an incalculable way.
