Never have I ever had so many needless calls, emails and texts and yet the poorest communication. Receptionist decided I was in need of a consultation appointment vs booking my colonoscopy. Sadly it was not communicated to ME. Day off from work wasted. I called and instead of just booking me in, they transferred me to the office manager further stretching an ordinary booking to a 3 act drama. Two weeks before the procedure, I got texts, emails, and calls to remind me to pick up my bowel prep. (???) I am fairly confident I’d know that. Then day of? They called to ask me to change the time of my procedure. Listen folks- this is not rocket science. You book, you poop, you get scoped. But in that equation is a person with a whooooole other life. Arranging for a ride means another person is “booked” so to speak. Have some courtesy for the person undergoing this not so great exam. This was painful enough to reconsider my next venue.

The entire staff were friendly, efficient and attentive from check-in, pre-op and post-op. Kudos to Dr. Kimbaris and the rest of staff that cared for me during my procedures.
