he’s awesome and extremely personable… Has a nice rapport about him… Glad I don’t have to see him for another three years though.

Dr. Schreiner is a wonderful doctor. He listens, makes certain that I understand everything, is patient, very knowledgeable and an asset to SWGI.

'clean cut', polite, efficient, friendly, thoughtful group of people. They covered me with warm blankets, and Summi administered a painless IV. Dr Schreiner took the time to talk to me personally after the procedure, instead of sending an employee. Medical offices are generally cold and impersonal. This clinic was a wonderful surprise!

Skilled. Good eye contact and bedside manner, ie, he is not an arrogant “god doctor.” One note: would prefer to receive results privately in recovery bed with spouse present rather than in waiting room with other patients

Dr. Schreiner was very professional, knowledgeable and friendly. He took the time to talk with me afterwards to explain my results. After having Dr. Mason for many years, I’m excited to have Dr. Schreiner as my new GI doctor.
