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.

A care for patients
Dr Gelernt is never in a rush! He genuinely ask you if everything is ok how is this how is that! Consider it done! I love that he is always on top of getting preventative tests and just has a great bedside manner! The staff is very pleasant and especially the techs!

1st visit
Dr spoke in terms I could understand. Eased my concerns about having mismatched bio valve. Ordered tests to determine if there were any other underlying issues.

After going undiagnosed for the first 40 years of my life and suffering chest pains and fainting spells for 20 years, two doctors out of so many took me seriously. I had open heart at Our Lady of Lourdes and the care I received from Dr Gelernt was wonderful. He’s a caring, compassionate man who takes time to listen and answer all questions. My husband is now his patient and is very happy with the excellent care.

I would like to give Dr Gelernt a zero for the care he provided my mother with during her stay in Inspira Hospital. He extended her stay in the hospital by "forgetting" to sign the proper paperwork for her discharge. After already being in the hospital for a week with pneumonia during the Covid Crisis, my mother and our family were overjoyed to have her coming home. Her spirits were lifted for a few hours, only to have Dr Gelernt dash them down. His incompetence is reprehensible.
