Patients Seen: All Ages

As an aller­gy, asth­ma and immunol­o­gy spe­cial­ist, I strive to pro­vide my pedi­atric and adult patients in the Joli­et, Naperville and New Lenox com­mu­ni­ties with the best care pos­si­ble. Aller­gies and asth­ma can have a tremen­dous impact on your dai­ly life. Whether you’re strug­gling with chron­ic sinus symp­toms, food aller­gies or skin rash­es, my goal is to work col­lab­o­ra­tive­ly with each patient to iden­ti­fy their spe­cif­ic aller­gens and devel­op a treat­ment plan best suit­ed to their indi­vid­ual needs. In order to achieve the best out­comes, it’s essen­tial that patients are includ­ed in the deci­sion mak­ing process and feel well-informed and com­fort­able, both with me and their care plan.

"I hope you're sitting down, this is gonna take awhile! First let me say that I'm a Doc Schubert fan and he is the Best Doctor ever! With that said, let's chat about the Doctor this survey is about. It was my first time seeing Doctor, he asked why I was getting the test I was getting. He listen to every word of my existing stomach issue. He had a few thoughts and questions on why I was getting a test to check for food allergies after I explained my symptoms but said let's do this test then I will go from there. After the test was complete, the Doctor came in, evaluated the area and mentioned that I showed a reaction to only one item. Here is where the visit is taken to a new level of care, the doctor asked if I was ever tested for celiac disease, I explained I didn't think so. he heard me mentioned in earlier conversation, I was concerned maybe I had a pancreas issue. The Doctor then said, I was reviewing your chart when you were getting tested, I noticed with the testing you had done, these two, (I forgot the two) May help identify your stomach issues. WOW! REALLY!? I'm there seeing a allergy specialist and he took time to offer his opinion and offer me his years of medical training advice!! Who does that!? I mattered to this man!!! Was I his only patient that day? I felt like I was his only focus! Never had I been care for by duPage medical with such focus on my care!!! thank you thank you!!! Please know that in my "my chart" I received what I think is a note from the Doctor himself, detailing his findings and an offer for additional medical assistance if I should need him! So to summarize, Doc Schubert is my life savior and I have him locked in as the best Doctor ever! well now we have a very close second!! Thanks a zillion!"
