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.

Dr. Duncan is amazing!. he's truly very kind, great listener, gives great advice and communicates very well. he made me feel welcomed and comfortable to talk to. I didn't feel rushed from my appointment. He's truly a rare, one of a kind doctor. 5 Stars indeed!I was also greeted by warm smile and warm welcome from the front check-in staff. The MA was very nice and explained everything she was going to do before doing it. she made sure the room was clean and follow the right contact precaution, for that she gets 5 Stars. I just wished I could remember her name as well as the front staff who checked me in for the appointment.ps- i was seen in the Farmington office

Above and beyond 5 stars!
Dr Duncan has been my 92 years young dads doctor, my cardiologist, my moms and brother in laws. He is the absolute best cardiologist. He is extremely patient, explains everything clearly, so professional and brilliant. Our family is beyond grateful for him and the outstanding care he has provide all of us. Additionally, when my dad has been hospitalized at a hospital over 30 min away, he graciously connects with the hospitalist and cardiologist there to discuss his treatment. In my heart of hearts, Dr Duncan is the reason my dad, who suffered a heart attack at 92, has had other heart complications along the way and a recent pacemaker- is still with us today. I trust Dr Duncan completely and am grateful for having him in our lives. He is the best. Maria, Tony, Toni Ann, Jon and family.

A very positive experience.
Dr. Duncan, in my visit, seems more like a friend who also happens to be a doctor. His concern is clear. In sharing insights from both his education and his experience, along with his ability to empathize, it felt very reassuring.

Definitely a top shelf cardiologist
Can’t say enough positive things about Dr. Duncan. Came to him in 2014 following a stroke. Dr. Duncan set me on a course of successfully managing my cardio health while monitoring my yearly progress through appointments and testing. Dr. Duncan’s calm, easy, efficient, professional style while always being informative and effective in his treatment is what anyone would want in a physician. Always available to respond on patient portal. Our appointments are always a good conversation. If you need a cardiologist, I would highly recommend Dr. Duncan!

An AMAZING Person!
I have had Dr. Brett Duncan as a primary cardiologist since 2008 when I first had a quintuple bypass. I have found him to be knowledgeable, approachable, respectful, articulate, caring, and patient beyond bounds. I walked in as a patient to see a doctor, and felt like I left as true friends in the deepest sense of the concept. He has always been available to be via phone or text and I respect that access and only contact him only when dire circumstances present themselves. I tell people truly, he "walks on water" for me - I regard him highly and thank my lucky stars every day that we crossed paths - I always feel that his care and persona are of a consummate professionalism that is rare to be found. I believe in him and would recommend him highly to anyone who needs the best in cardiology services TOMMY MEEHAN

Dr Duncan is a knowledgeable, kind, friendly and caring person. He is reassuring and makes me feel extremely comfortable i his presence. He does not act like he is superior like some doctors do. I would definitely recommend him to friends who need a cardiologist.
