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.

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.

My first visit to Dr Alex Brun was a pleasurable one. Dr. Brun was very attentive when I was talking about my issue. Responded to any and all concerns I had with care and detailed explanations. Made me feel very comfortableto talk about things that normally are uncomfortable to talk about. He was very professional and well mannered. The staff at the reception area were very pleasant and professional as well. The wait was about 15 minutes or so. Over all a five star experience. I highly recommend Dr. Alexander Brun.
