The Kagen Allergy Clinic, S.C.

The Kagen Allergy Clinic, S.C. is an allergist in Fox Crossing, WI, located at 100 W Lawrence St Unit 410. The clinic is part of a four-location practice serving Northeast Wisconsin from offices in Appleton, Oshkosh, Green Bay, and Fond du Lac. Patients can be seen in person or through video office visits, and the practice runs allergy and asthma testing, treatment, and telemedicine visits across all four clinics. The Appleton location, which houses this address on West Lawrence Street, is open Mondays from 8 AM to 5 PM, with shot hours from 9 to 11:30 AM and 1:30 to 4:30 PM. Patients book appointments by calling 920-739-9100 or reaching the central line at 800-ALL-WELL.

The practice focuses on allergy, sinus, and asthma care for both adults and children. Steve Kagen, M.D. leads the clinics with decades of allergy and immunology experience and treats conditions that include allergy, sinus pressure and headaches, itchy and watery eyes, anaphylaxis, eosinophilic esophagitis, cough, asthma, wheezing, eczema, hives, bee sting reactions, food allergy, and drug allergy. He holds a U.S. patent for the discovery of a dust mite allergen, received an EPA Children's Environmental Health Recognition Award for creating The Allergy Family Guide, a classroom-ready asthma and allergy education program for fifth-grade students, and was voted by Wisconsin physicians as one of the Best Doctors in America.

Alongside clinical care, the practice has built its own digital tools for patients: the patented KagenAir mobile app, which uses artificial intelligence to track how weather and the environment affect symptoms, and the Sensitometer test app for measuring individual sensitivity. The clinics also publish the Kagen Allergy Report, tracking pollen and mold spore levels across the region, and operate the National Pollen Network and a diagnostic allergy-immunology lab called AllerLab.
