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. Trimmer definitely has saved my life so far.
I am sad to say that he is retiring although he absolutely deserves to, I will miss him very much!! He is a top of the line doctor that never cuts corners or assumes he is one of the most thorough doctors I have ever met. Doc you WILL be missed!

Cardiology
I am a pulmonologist and Dr. Trimmer has followed my Aortic valve for 30 years and basic associated heart health. Points: 1. Always responsive same day for complaints.2. Does not hesitate to follow up office same day or next if appropriate even if schedule is full. 3. I deal with Covid patients daily as a pulmonologist and he knowing this got me right in with the findings on a preliminary preop visit severe aortic stenosis and the next week he had me scheduled for TAVR a very new catheter Aortic valve replacement which would allow me to return to work in a couple of weeks rather than several months after surgical aortic valve replacement. Note you do not go home one day after an aortic valve replacement with surgery . Final note comment: Dr. Trimmer is a patient caring physician and even with other doctors which is not easy because we are very demanding. Highly recommended. Dr Stephen Lillard DO FACA FCCP

My husband needed either bypass or stent. Dr. Trimmer was able to place a stent. No complications, information was clear and precise and the doctor and staff were pleasant and answered all questions. We would highly recommend this doctor.
