A History of Denver Allergy and Asthma Associates
After finishing his Fellowship in Clinical Allergy at National Jewish Hospital in 1972, Joel Karlin became head of the Allergy Clinic at the Air Force Academy in Colorado Springs. As that tour of duty was finishing, he worked in the Emergency Room at St. Anthony Hospital taking care of allergy and general pediatric problems. He also met many of the West Side doctors in the Denver area. In the spring of 1974, he started his own allergy practice in Lakewood, founding Denver Allergy and Asthma Associates. Dr. Karlin worked with many of the doctors at both St. Anthony Central and St. Anthony North hospitals so, in addition to his initial Lakewood office, he quickly added an office next to St. Anthony North Hospital. In the spring of 1975, Gary Siegel, who also trained at National Jewish Hospital had finished his Army tour of duty at Fitzsimons Army Medical Center as Assistant Chief of the Allergy Clinic and Fellowship training program and had just started his own allergy practice in southeast Denver. Dr. Karlin was going on a well-deserved vacation for a few weeks in the fall of 1975 and asked his friend, Dr. Siegel, from the allergy training program to “cover” his practice. Dr. Siegel enjoyed the very busy work schedule at Denver Allergy so much that the two decided to join their three offices together. Denver was growing rapidly, as was the practice and it wasn’t long before additional offices were needed in Arvada and southwest Denver.
