Your trust is our top concern.

We strive to keep the reviews trustworthy, honest & fair.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

Worst Doctor I have ever had in my life! She doesn't care about her patients, she doesn't care about people, or the health care industry. She laughed to my face about my health concerns with my family present. She didn't assist me with any of my needs. She has an extremely terrible attitude, and shouldn't be a doctor. She acts like she doesn't want to talk to you, acts like she doesn't have time for you, and doesn't show any compassion for your health needs. I would seriously be dead if she was still my doctor.

She is very nice. However, I didn't feel she answered my questions appropriately and in fact advised me unwisely on one of my conditions. I had no confidence in her. She was very mild mannered and a little wishy-washy.

I thought she was really good at listening and determining the right way to go on something that was a bit unusual. She's my primary care physician, so she sends me elsewhere for such things. Also, I never wait very long at her office.

My mother and I have both been patients of Dr. Gentemann for over 15 years. She is an extremely knowledgeable and caring physician. She always listens to our concerns and is dedicated to helping find answers to our medical issues. I would never consider going to anyone else, and I highly recommend her to anyone.
