Dr. Schulman and the staff at the Glendora Digestive Disease Institute are amazing! The doctor and the CRNA explained the procedure in a way that was easy to understand, even for someone not in the healthcare field. During the procedure, I felt completely comfortable and didn’t feel a thing. I’m very impressed with the skills and knowledge demonstrated by both the doctor and the staff. Everyone made me feel at ease from beginning to end. As someone who also works in GI, patient comfort is always my top priority, and I’m grateful to have experienced that level of care myself. Thank you, Glendora Digestive Disease Institute! My husband and I will definitely be returning for our follow-ups in the years to come.
