Allergist / Immunologist

Dr. Joel Klein’s training in pediatric and adult allergy/clinical immunology was a three-year fellowship in allergy/immunology at Mayo Clinic, which followed his internship and residency at Rush University Medical Center. Born and raised in the city of Chicago, he returned to the Chicago area after completion of the fellowship training and has practiced as an allergist in the northern suburbs since 1995.

Among his professional activities, Dr. Klein is a past president of the Illinois Society of Allergy, Asthma and Immunology. He was honored subsequently with the society’s position of historian for 10 years. He has had a faculty appointment as Assistant Clinical Professor of Medicine at Rush Medical College and has given monthly lectures on allergy/immunology since 1997 to medical students, interns and residents who have rotated through Skokie Hospital. Recently, he is one of the committee members who wrote questions about safe steroid use for a teaching module from the American College of Allergy, Asthma and Immunology.

Dr. Klein has authored and co-authored a number of publications in the specialty of allergic diseases. He is recognized by the peer nomination-based rating organizations Castle Connelly (since 1999) and the Center for the Study of Services (since 2011) as a top allergist in the Chicago area. He has also received recognition from patient-based Internet physician rating websites.

When not in the office, Dr. Klein is spending time with his family and engaging in personal interests that include U.S./world history, films, tennis and late 19th/early 20th century art history. And, he has joined a new fantasy football league this year—after his mentors at Mayo Clinic retired the league that they invited him to be a part of for 23 years.
