Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Professional, personable, caring doctor
Her preparedness, caring personable interaction, including importantly listening; and calm detailed plan is laudable in this day.

Unresponsive
Tried to get an appt with her. Called 3 times. No one called back. Finally, they said she wouldn't see me because I had previously seen a different dr at AZDH, even though it was a different location and that dr doesn't do the test I needed done.

Best Gastroenterologist
I have been a patient of Dr MacCollum for over 20 years. There has never been a time that I questioned her advice and I believe that I am a healthy 66 year old today because of her. What I love most about Dr MacCollum is that we have an open dialogue about my health and we discuss how best to move forward. Barbara MacCollum is one of the most professional doctors I have ever met, and she is just in overall wonderful human being. Not only is she second to none, so is her entire staff.

A patient for 20 years.
20 years ago Dr. MacCollum performed an EGD because I had a problem swallowing. I am scheduled for another one because the problem started again. During the interim I had 2 colonoscopys. I plan to have a 3rd colonoscopy in 2 years again with Dr. MacCollum. I highly recommend Dr. MacCollum.

FANTASTIC DOCTOR & COMPASSIONATE
There aren’t enough words to express how much I think of Dr MacCullom. She is THE BEST in her field. Caring. Compassionate. The scheduling was smooth and efficient. Dr. M identified my issues immediately and explained them in details. I could ask whatever I needed and Dr MacCullom never looked at her watch. I felt so safe and cared for. Her staff is just as kind and fast and efficient. I do not write reviews very often. But Mr MacCullom and her Staff deserve high praise, especially in today’s environment where everything feels rushed and no one has time to make you feel human. If you are lucky enough to find your way to this doctor, then count your blessings!
