Our Doctors and Staff

We focus on you—your comfort, your concerns—as much as the treatment techniques and options. When we say, “The doctor will see you,” we mean exactly that. You’re not making an appointment with a nurse or physician assistant, just your doctor. We promise:

+ A one-to-one doctor-patient relationship.
+ Fewer forms, less waiting, more listening.

Your comfort is our main concern, and you need effective, long-term solutions. We take the time to help you take back control of your life.

Affiliated Hospitals

Our physicians have staff appointments at a number of Denver Metro area hospitals. Though our hospital privileges do not allow us to directly admit patients, we are available at the following hospitals for consultation and to provide the hospitalist or primary care physician assistance in managing inpatients and coordinating outpatient follow-up.

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 and meeting many of the West Side doctors in the Denver area. In the spring of 1974, he started his own practice of allergy 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–Read Complete Short History +

Dr. Bill Newman, MD

Dr. Newman grew up in Dayton, Ohio, where he lived and breathed Reds baseball. He received his undergraduate degree in biology from Yale University. While there, he worked in the immunology lab at the medical school, a position that sparked his interest in the field. He obtained his medical degree from Case Western Reserve University on an U.S. Army scholarship and did his internal medicine residency at Fitzsimons Army Medical Center in Aurora (now the University of Colorado Anschutz Medical Campus). He spent the next 4 years as a staff internist at the US Army Hospital in Heidelberg, Germany.
He left military service in 1997 and joined the staff of the University of Vermont where he was also assistant professor of medicine, teaching medical students and residents. After 3 years in primary care internal medicine, he decided to seek specialty training and re-joined the Army to do so. He completed his allergy/immunology fellowship at Walter Reed Army Medical Center in 2002, and from there returned to Germany to become Chief of Allergy at the US Army Hospital in Würzburg where he also functioned as Chief of Medicine. As an Army allergist he treated patients of all ages, including soldiers, family members, retirees, and civilian employees. He left Germany and the Army in 2005 to launch a solo allergy/immunology practice in 2005 back in Vermont.
He spent the next 11 years as an established allergist in the Burlington, Vermont area. When his son graduated from high school, he and his wife decided to make a bold change, and return to Colorado. He joined Denver Allergy & Asthma and Boulder Valley Asthma and Allergy in July 2016.
Dr Newman is passionate about delivering high quality specialty medical care to his patients and has a broad set of interests in allergy and general medicine. An outdoor enthusiast in all seasons, when not at work he loves the wilderness and the mountains, camping, hiking, canoeing, and fishing whenever he can find the time. He is married and has a son who will be starting at CU in Boulder in the fall 2016.

Dr. Jeffrey S. Rumbyrt, MD

Dr. Rumbyrt grew up in the Chicago area where his love of baseball (White Sox), White Castle hamburgers, and science was first kindled. He first became interested in medicine after visiting a genetics research lab at Argonne National Laboratory while in high school.

He joined Denver Allergy and Asthma Associates in 1994 and has served as its President since 2000. He has a special interest in the treatment of chronic hives, chronic sinusitis, and asthma and is an active lecturer on these subjects as well.

Dr. Rumbyrt has earned the reputation as one of the practices’s “traveling allergists” as he attends clinics twice a month in Eastern Colorado and Western Kansas, logging almost 10,000 miles per year in his reliable mini-van. The monotony of travel is mercifully broken by a constant supply of books-on-tape making him one of the best “least-well-read” doctors in Denver (a category yet to appear in 5280 magazine). His wife of over twenty years, daughter, and two sons occasionally giggle at his various voices and attempts at humor. He has difficulty with the driving games on the Wii. His free time is spent coaching youth soccer, basketball, and baseball and mining statistics for his fantasy baseball team.

    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 and meeting many of the West Side doctors in the Denver area. In the spring of 1974, he started his own practice of allergy 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.

In those early years, patients with asthma often had serious, life-threatening episodes, often requiring emergency room visits, hospitalizations, including ICU care with respirators that would breathe for them. For Dr’s Karlin and Siegel, weekend call would mean frequent hospital visitations to various hospitals to check on the patients. Being “on-call” often meant anything from fielding questions and phone calls throughout the night from patients who were starting to wheeze, to middle-of-the-night hospital admissions. Some patients had fairly precarious respiratory courses. Over the years, with the advent of newer and better medications, the typical course of patients with asthma has significantly changed. Knowledge of how to advise patients and the use of much-improved and amazingly effective medications has totally changed the course of asthmatic patients. Patients who previously would have been hospitalized many times per year now have to be coaxed into coming in for routine, but necessary, “well-patient” checkups. Times have changed markedly for the better – for patients and physicians!

In 1981, practice volume continued to increase and Francine Andrews, who had just completed her Fellowship at National Jewish, joined the practice. During this time, Dr. Karlin felt that many rural areas of Colorado were underserved by specialists and that it would be helpful to have allergy specialists consult on patients with allergic problems referred by the local doctors. As a result, the physicians of Denver Allergy began serving patients in Burlington, Hugo, Salida, Buena Vista and Leadville, Colorado as well as Goodland and Syracuse, Kansas. At the present time, we continue to serve the communities of Buena Vista, Burlington, Goodland and Hugo on a monthly basis.

In 1994, having finished his Fellowship at National Jewish, Jeff Rumbyrt increased our doctor roster to a total of four. From 1995 until 2001, the practice upgraded and/or moved its office locations in Arvada and Westminster, settling in at our present locations at 80th Avenue and Kipling Street in Arvada, and 120th and Pecos Street in Westminster. In January, of 2001, Dr. Rumbyrt assumed leadership of Denver Allergy when after Dr. Karlin resigned from full-time practice to concentrate his efforts in a private business venture. In May 2001, the day before the practice was to relocate its main office from 14th Avenue and Garrison Street in Lakewood to a newer, larger office space in the Denver West area, Dr. Karlin suffered a significant health event that left him comatose for twenty-one months until he passed away in February, 2003.

The practice regrouped and with difficulty continued on. By 2007, Dr. Siegel was interested in decreasing his hours so this enabled Paul Schkade to come on board. Dr. Schkade had completed his Allergy Fellowship at Fitzsimons Army Medical Center, (which was affiliated with National Jewish Hospital) and had been in private allergy practice in a large medical clinic in Arkansas for a dozen years. With a yearning to return to Colorado, he joined our practice in the Spring of 2007, bringing the number of allergists back up to four.

Today, Denver Allergy remains one of the busiest allergy and asthma practices in Colorado. We currently serve over 6000 active patients in our five Denver Metro offices and four rural clinics. As Denver has grown, we have also experienced significant growth and changes to our practice. It is with our solid founding, our resiliency through many challenging events, and our desire to provide the most comprehensive allergy and asthma treatment that we look forward to serving our Colorado and Kansas patients for an additional 40 years (and beyond!).
