Colonoscopy helps patients examine the colon and rectum, often considered the most recommended choice for colon cancer screening.



Upper GI endoscopy, or EGD, helps provide a visually clear examination of the entire esophagus, stomach, and duodenum.



Hemorrhoids are internal or external conditions that can cause bleeding and develop from diarrhea, obesity, injury, or liver disease.

This is the best medical office I have visited. Dr. Davidson is unique, he is professional, knowledgeable, and compassionate about his care. He was very informative and was clear about the procedures every step of the way. I appreciated how consistent he was in checking on the progress of my recovery. His staff were also a helpful bunch and responded immediately to my questions. I cannot say enough in a single review how happy I am with finding a great gastroenterologist. Thank you, all of you!

I’m so grateful that I had the opportunity to meet Dr. Davidson and his team. I had suffered from extremely painful acid reflux. I could never enjoy any of the food that I loved the most. Unfortunately I learned that it was this food that was part of the problem that was causing my stomach to suffer, but with the help of Dr. Davidson my condition has improved dramatically in the past 6 months that I’ve been treated. I learned how to take care of myself and each day I just feel healthier than before.

Great office and there was barely any waiting for the appointment. Dr. Davidson could not have been a nicer and more knowledgeable doctor. I had my first colonoscopy here and it was a routine procedure, all questions were answered and the entire office was patient and respectful.
