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.

Highly Recommend
Dr. Keller responds to concerns emailed, texted or called in, within minutes! He is always kind and calm. He always spends time with you without any rushing during visits. Another doc said of all the docs she communicates with, no one has his degree of patient recall nor responds as quickly as he does. He successfully treated me during a first afib episode when acutely ill after surgery, with a recommended response that was the least invasive ( just remove the intubation) to years later a cardio version and later, an ablation. Following medication treatment, my afib condition has been successfully managed. I trust Dr. Keller’s judgement, skills and overall care.

He installed a looper recorder in my chest at the hospital, and it is perfect. I give him 5 stars.
