Went in for routine colonoscopy ... yeah, no one's favorite visit to a doctor. Getting through and scheduling was a little challenging, but much of that is probably COVID related. Staff was pleasant and helpful once I reached them, and always responsive through the portal within 24 hours. Getting back to Dr. Parker and the procedure - I assumed he would be medically capable based on his training, and he is - but just as importantly and things you can't tell just from reading someone's CV - he was pleasant, down to earth while still being professional, calming to this slightly nervous patient. The procedure itself went smoothly from start to finish. I hope not to need a return trip for a long time... but would highly recommend Dr. Parker and his practice.

Dr. Parker is the most caring medical doctor I have ever met. He takes the time to listen and address my medical needs. After having lab work, he followed up and called to give the results. I had previously seen a doctor at Johns Hopkins and was not happy with his lack of compassion and empathy for me. Hands down this is the best doctor and I recommend Dr. Parker to everyone who needs a GI specialist.

Dr. Parker was excellent! He explained everything to me in detail of what was going to happen in a language I could understand and was patient with any questions I had. He treated me like I was a part of the process, not just a number or a bystander. He made me feel safe and the I was in good hands.

I was very pleased with my appointment with Doctor Parker. I have had problems with my digestive system for several years and after many many tests and procedures have still not been able to live a normal life!! My first appointment with Dr. Parker was yesterday and he plans on exploring all of the possibilities and not jumping to a conclusion as to the nature of my problems. To me, he seems to be a problem solver and that is what I need!!!

As a person with severe disease, Dr. Parker and his office are wonderful in my care. He listens and explains everything in layman’s terms so I can understand all of my results and my treatment plan without feeling like I needed to do a year of med school to understand. Definitely recommend his office to anyone that has GI issues. I’ve met random people in crossing that also have him as a dr and they have said the same about him.

The Dr. gets a 5 star from me. I was flabbergasted that prior to my first visit he had looked up my previous medical history and read my colonoscopy/endoscopy reports. Very thorough. Told me like it was. Didn't sugercoat anything. Repeated directions twice and how we were going to proceed with my treatment(s). I feel confident he is going to get me healthy and do his best to keep me healthy. Thank you!!!

Condescending. Not interested. He tries to get you (the patient) to make the decision of treatment. Total waste of time and money. So rude.

Dr. Parker was awesome. He sat with me to explain everything, including his impression, what to expect during and after the procedure. Even more impressive, he did not conclude the visit until all of my questions were answered.
