I just love Dr. MacCollum! She's so nice and makes you feel very comfortable. She did my colonoscopy and made the whole process so easy! Her office staff and PJ, who does the surgical scheduling, are all great. For anyone that is looking for a wonderful doctor, I would highly recommend her! I am so thankful that I have her as my doctor.
