History of Allergy, Asthma and Immunology Associates

Dr. Rosemond Romero, M.D.
In the late 1960s, Dr. Rosemond "Rosie" Romero came to the Valley after training in Denver, Colorado.  This transplanted Cajun from Louisiana quickly made his mark on the medical community.  Dr. Thomas Hartley, originally from Arkansas, joined Dr. Romero in 1969 to form Allergy and Immunology Associates, Ltd.  They set the standard in allergy and immunology care in the Phoenix and Scottsdale areas.  This partnership continued until 1992 when a native Arizonan, Dr. Michael E. Manning, returned to the Valley to join the practice where he once received allergy shots.  Dr. Manning quickly accepted the charge to keep Allergy and Immunology Associates at the forefront of allergy care. A unique quality of this business was that they were able to retain nurses and other staff for prolonged periods of time because of their values and work ethic.  Jean Nelson, a registered nurse with the clinic for 15 years, went back to school to obtain certification as a Nurse Practitioner.  Like Dr. Manning, she returned to the clinic in her new role in 2003.  The practice, keeping up with the national trend of emphasis on asthma care, changed its name to Allergy, Asthma and Immunology Associates. In the summer of 2005, Dr. Aaron Davis joined this distinctive practice.
