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.

Wonderful doctor!
What a relief to see a doctor who takes his time, listens, is friendly, and provides extremely helpful care. He even takes handwritten notes and was interested in medical history. It felt like going back in time (in the best way!!!) to when medicine was less rushed and more caring. And the new patient coordinator was fantastic, along with other staff who helped with scheduling, assisting with the patient portal, etc. Thank you, Dr. Rennert, for providing a kind of care that is SO needed.

I have been a patient of Dr. Rennart for approximately 8 years. In this time the doctor has helped me prolong my working career and life through medication therapy and education. He is kind, empathetic and knowledgeable in his field of expertise. I would gladly recommend him to all family and friends suffering from pulmonary or coronary diseases. He is truly blessed in his field. Thank you Dr. Rennart!! Respectfully, Mike
