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.

Please come back Dr. Kotzan
I used Dr. Kotzan for many many years. She was always compasionate and never rushed me. Although wait times were sometimes long, I attribute this to the fact that she probably was giving all of her other patients the same attention she gave me. The wait was always worth it. I wish she hadn't closed her practice due to the beuracracy of the Northwestern Mediciine group. If she ever reopens in another location I will definitely use her again as my primary physician. I miss her and her staff. The Northwestern Medicine group has made the experience very cold, difficult and unpleasant. No bedside manner. It feels like the whole experience is about the money.

Dr.Kotzan has been my doctor for over 2O years. I attribute my fabulous health to her excellent care. She is a compassionate listener who takes time to thoroughly get to know her patients.

Dr. Kotzan gaslighted me into thinking that I was somehow faking the pain of severe ovarian torsion from a melon sized ovarian cyst, misdiagnosed my strep throat as malingering on two occasions and generally made me feel as small and insignificant as possible. Please find another doctor, if you're looking. I would give anything for the time and wellness that she cost me back.
