My appointment for Dr Brun was for a colonoscopy / endoscopy. I waited for about 30 minutes then was prepared for the two procedures. I was done in about 30 minutes, then waited for the anesthesia to wear off. Meanwhile Dr. Brun discussed the results with me, then I was on my way. HIs professional staff also made the visit pleasant.
Very high professional Thank you
Dr. Brun seems very knowledgeable and easily approachable. However, two hours is way too long of a wait for an 8:30 am appointment. Also, the restroom in the waiting/reception area was ATROCIOUS! It was unclean and there was no paper. Unacceptable for a doctor's office.
Doctor is very good and I would definitely recommend him
Dr Brun is excellent doctor! Very pleasant, polite and professional. He responded to all my questions. It feels like he really love his job and his patients. Highly recommend him to everyone!
