A really great experience. Staff was very friendly and attentive. I called office to ask for an alternative to the prep solution. I was given the option to use over the counter meds. Dulcolax and Miralax, tasteless drank with my favorite juice. These meds worked way better than the prescribed meds. I had a great Colonscopy experience.
