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.

I have been a patient of Dr McKenzie since 2008 and have had no negative experiences. He always takes the time to listen to my concerns and offer his recommendations. Having had 2 bypass surgeries, prior to being a patient of Dr Mckenzie, and I tend to be overly concerned whenever I have what may be angina. Dr. Mckenzie always takes the time to ease my concern by explaining what constitutes angina pain what doesn't. You can't go wrong with him.

Elderly mother was his patient, we really liked him at 1st. His attitude changed, it was like he didn't care. Her bp was very high after heart attack, kept a journal of it. At a visit, he didn't want to see it or take her bp. No one did. Just kept upping her meds. We had a concern about her calves hurting when she walked. We asked if it was her arteries. He kind of laughed, said it was arthritis. Went to another Dr. She has extensive clogging of arteries. She has to have surgery ASAP.

I am a patient of Dr. Clark McKenzie, (Since spring of 2003), I feel I get excellent care and advice from him. For 13 years I have used this doctor for Heart and related medical problems. I get clear, direct answers and for me, that is important.. Whether the discussion is with a family member, friend or YES on Facebook and Twitter, I enthusiastically recommend Dr. Clark McKenzie.
