Dr. O’Hollaren obtained his Bachelors degree in Chemistry from Gonzaga University in Spokane, Washington. After earning his MD degree at the Oregon Health and Science University, he completed his internship and residency in Internal Medicine at Stanford University Medical Center in Palo Alto, California. He then completed a fellowship in Allergic Diseases at the Mayo Clinic in Rochester, Minnesota.
Dr. O’Hollaren has served as President of the American Association of Certified Allergists, and was elected Chairman of the section of Asthma, Rhinitis, and Respiratory Diseases for the American Academy of Allergy, Asthma, and Immunology, the largest organization of allergists in the country. He was also elected to the Board of Regents of the American College of Allergy, Asthma, and Immunology, and served as Vice-Chairman of the Committee on Asthma and Respiratory Diseases for that organization.
One of Dr. O’Hollaren’s favorite pastimes is teaching. His most cherished award is the Excellence in Teaching Award, given by the medical students at OHSU. He has presented over 400 invited lectures locally, nationally, and internationally. He has been the top rated lecturer at the American College of Allergy, Asthma, and Immunology Annual Literature Review, held during the annual convention of the ACAAI, for twelve of the past fifteen years.
Dr. O’Hollaren has published in numerous scientific publications including The New England Journal of Medicine, Chest, the Annals of Internal Medicine, the Annals of Allergy, the Journal of Allergy, Asthma, and Immunology, Emergency Medicine and many others. He has served on the editorial board of the Annals of Allergy, and served as co-editor of the textbook Occupational Asthma. He is very interested in expanding the use of the internet for medical education, and is currently an editor for the both the Pulmonary and Allergy sections of WebMD/Medscape.
He has just finished a joint, multi-year research project with both OHSU and the Kaiser Center for Health Care Research developing a tool to prospectively identify high-risk asthmatics in the general population. On this project, he has worked for nearly ten years with Dr. Molly Osborne at OHSU and Dr. Bill Vollmer at the Kaiser Center for Healthcare research to help identify those at risk for hospitalization or other severe complications from asthma. This work was recently published in the journal Chest. The focus of his current research is the development of new tools to help identify high-risk asthmatics, so that targeted intervention may be instituted before their asthma worsens or flares.
Dr. O’Hollaren spends significant time with each of his patients, and takes care to listen to them carefully. He also has a special interest in asthma in elite athletes, and has worked extensively with athletes with asthma from around the country, including those on the U.S. Olympic team, the Nike team, and numerous universities and high schools from around the country. Partly as a result of that work, Dr. O’Hollaren was the inaugural recipient of the Alberto Salazar “Asthma in Action” award from the American Lung Association, given for his work to increase public awareness of appropriate asthma care.
