The nurse (Barb?) and Doctor Raymond M. Pongonis Jr., MD were awesome. Just a great experience for my first ever allergy tests! They made it comfortable and a positive experience. Thank you to the awesome staff!!!

The bedside manner at the Elmhurst, Oak Brook Allergist is top notch. I feel like they genuinely want to help me get better and are interested in finding the cause. Appreciate there help!!

I’ve been a patient at OakBrook Allergists for years and would never go anywhere else. All of the providers - doctors, RNs, APNs are great and the receptionists are kind and friendly. Don’t wait - make your appointment today, you will feel better.

The doctors and staff at Oak Brook Allergists are fantastic. I am a few weeks away from completing the Peanut Oral Immunotherapy program and the professional and administration of the program are top notch. I had a lot of anxiety about the program but Dr. Rubin, Dr. Pongonis, Donna and the rest of the team took great care to walk me through the program and the guidelines for success. I even had an accidental peanut exposure before the program was complete and did not have to use my epipen. The program has been life changing. Thank you Oak Brook Allergists!

Great! Very helpful in person visit with the doctor. Staff and nurses were great. Very easy to get in and make an appointment.

I would never recommend going to Oakbrook Allergists, if you want allergy treatment. While the nurses and secretaries were always very kind, this practice put me on a subclinical dosage schedule with only placebo results to show for it. (I thought I saw results, I got retested and realized I didnt, I likely thought that since I started taking more medication during the time I started coming to Oakbrook Allergists).This place will put you on a very low and frequent dosage to minimize the risk of reaction to you and maximize the amount of payments they get. Granted, if that is what you want, great. Just know that it will likely never get you to the relief you are looking for. Any benefits on their ultraconservative dosages will likely be from the placebo effect. After 3 years and 3 months I was retested at another, more legitimate and ethically practicing, allergy clinic. In 6 visits, I will reach the same dosage as 3 years 3 months at Oak Brook Allergists. Oak Brook Allergists practice unethically and do not appear to follow evidence based clinical results. I will be reaching 1:1 serums eventually for reference at the new place. Absolutely ridiculous.Tips for finding an allergist: get retested at a specific time interval to ensure clinical results over placebo, do not let them milk your insurance and your time on 1-10,000 and 1-1,000 injections, ask at what matinence dosage the current research shows clinical results for the majority of people (allergy test results, not placebo).Best of luck searching, if I could take back my time and money at this place I would.

Back after 17 years and it’s as if I never left! Such a great office!

Awesome staff very professional

My son and I have relied on Oak Brook Allergists for a number of years. The office staff is helpful, friendly, and courteous, the nurses friendly plus professional. Dr. Knysak has been my main doctor. He is extremely approachable, very thoughtful, and very knowledgeable. I would recommend this medical to anyone seeking good, professional, expertise in the allergy field.

I think they’re okay to go to with minor issues, or easily controlled asthma and allergies. But I recently had an asthma attack, Ive decided to find another doctor.

I went there they told me I will just pay the Co payment only. After that I found a bill for 230$ for allergy test which was negative and they were confirming that no more payments in addition to the original Co payment. So depressed because they should verify the benefits before giving me the service which will never cost this amount.

My experience was bad. Not only I was there for 2 hours. I did a copay for $45 and still got another bill. Not a professional place. I was charged for things I dont understand.
