"The doctor is good… you spend more time waiting for him than the visit itself though.. but he will talk to you about your concerns and answers your questions…. But staff need to ask you when you would like to come back instead of making an appointment for you and then needing to reschedule the appointment because the time and date doesn’t work for you… they need to remember that people do work and some have hard times taking time off…another thing it is very very hard to get ahold of someone at the office when you call in as well. They also will tell you they will mail out the prep information for the colonoscopy to you in the mail and you never get it so you need to call the office to get the information over the phone of what needs to be done, or Google the information online"
