About Us
Allergy, Asthma, and Immunology was formed in 1975 in Lincoln, Nebraska by Dr. Fred Kiechel and subsequently Dr. Melvin Hoffman. Their dedication to excellence in patient care led to the expansion of clinics across Nebraska and Iowa.
Our team of board-certified allergists specializes in the diagnosis and treatment of allergies, asthma, and immune deficiencies in both children and adults of all ages.
