Dr. Maccollum is wonderful to work with. She takes her time with you, and her office staff just couldn't be nicer. I went to her for a colonoscopy, and the facility she uses is equally wonderful. Great staff, kind and competent, and they use a milder form of anesthesia which is terrific. I highly recommend her.

I was called three times to make my appt and the day of my appt I received a call saying they would not accept my United health plan. They had weeks to verify but it was verified on the same day of my appt so I strongly advise patients to make sure your insurance is accepted or you will have wasted all your planning to make room in your schedule for this doctors office like I did.
