Get to know Allergist and Immunologist Dr. Gary C. Steven, who serves patients in the State of Wisconsin.

Dr. Steven, a board-certified allergist and immunologist, established the Allergy, Asthma & Sinus Center, S.C. as a solo, independent practice in February 2003 in order to continue to deliver high quality, comprehensive care without undue, external influences or expectations. 

Today, he works alongside Dr. Don A. Bukstein, MD, providing the full range of allergy services for both children and adults at clinics in Greenfield, Milwaukee, Mukwonago, and Mount Pleasant, Wisconsin. They pride themselves on meeting their patients’ individual needs, providing the highest quality of service, and offering rapid appointment availability.

On the subject of his educational background, Dr. Steven received both his Bachelor of Science degree and his Doctor of Philosophy degree from the University of Wisconsin – Milwaukee. He then went on to earn his medical degree from the Medical College of Wisconsin. After a residency in internal medicine, he completed a fellowship in allergy and immunology, both at the Medical College of Wisconsin.

Before long, he became board-certified in allergy and immunology by the American Board of Allergy and Immunology (ABAI). The ABAI was established in 1971 as a Conjoint Board of the ABIM and the ABP. The Board is committed to working closely with its parent boards to maintain the highest educational and clinical standards in the specialty of allergy/immunology.

Actively involved in several medical organizations, Dr. Steven is a member of  the American Academy of Allergy, Asthma and Immunology, the American College of Allergy, Asthma and Immunology, the World Allergy Organization, the American Medical Association, the American College of Physicians, the Association of Clinical Research Professionals, and the Academy of Pharmaceutical Physicians and Investigators.

Allergy and immunology involves the management of disorders related to the immune system. These conditions range from the very common to the very rare, spanning all ages and encompassing various organ systems. An allergist-immunologist is a physician specially trained to diagnose, treat and manage allergies, asthma, and immunologic disorders, including primary immunodeficiency disorders. Recognized for his expertise in the field of allergy and asthma, Dr. Steven was selected by Milwaukee‐area physicians to Best Doctors in America, a listing of the best 4% of U.S. physicians.

A resident of New Berlin for 24 years, he lives with his wife, Rene, and their two children. In his spare time, he enjoys bicycling, scuba diving, woodworking, and photography.
