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.

Caring doctor
Dr. Koewler’s office is always punctual and considerate of your time. He is very thorough when you see him and truly cares about you and your family.

Caring and Competent
At 71, my litany of minor ails and complaints can sometimes mask something more serious. Dr K worked through my issues and discovered a new problem, A-Fib. Meds for now and a consult with a specialist. All while making me feel like a valued patient.

Best for Last
Everything about Dr. Koewler is fantastic. He is easy to talk to and very nice. He remembers all of your families names and always asks about them. His staff is also excellent especially the nurses. They are very easy to get ahold of when you have any issue going on and return phone calls promptly. I saved the best for last. I never wait more than 3 or 4 minutes in the waiting room or once taken back. Highly recommend Doc. You won’t be disappointed.

Comforting and pleasing personality.
Dr. Koewler met me where I was emotionally , and psychologically by stating that I had come very well prepared, in that I brought a list of my current meds, and a copy of the Lab Report which had been ordered at Urgent Care. That gave me assurance that he was in control of the issue for which I was concerned.
