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.

No I could never recommend this Doctor. He totally was wrong about diagnoses and the treatment could have made me even sicker. Thank God I went to Northwestern for second opinion.

The office staff is excellent, and Dr. Rademaker listens to all of my concerns. They always get me in when I need an appointment. Please consider this office if you need to find an allergist. You will n to be disappointed.

I would not recommend anyone in their 20 to 30s see him. For some reason I was told to take my top off fully just to listen to my breathing. My father came in and was asked to leave and all he did was hear me breathe. My own primary has never had me do that. It was very uncomfortable and I will not be going back ever to see him. His staff were not very friendly either.

This is a very slow office. My daughter has bad allergies. Took over 2 months for an appointment. Doctor took 3 minutes and said she needed the test for shots. Took another month because they only do needle test once a week. She took the test. Said it would be 2-4 weeks to get serum made. They only have one person who comes in once a week to do this. That’s absurd. How can you run an allergy office without proper help. Called and left messages. Wrote to head office. Took 2 weeks for a reply.

Dr. Rademacher wanted to put my son on a very strong med at a very young age for mild asthma. I was not happy. We found another allergist and never went back. From what I have seen he tends to overmedicate.

Dr. Rademaker goes above and beyond. He has his office call with suggestions to help, he tries to find coupons to save on prescriptions, he listens to everything you say and goes from there. Very Kind.
