Betty A. Petrak, M.D. received her medical degree from New York Medical College. She trained at North Shore University Hospital/Cornell Medical Center and Memorial Sloan Kettering Cancer Center in Internal Medicine, having firsthand experience with the developing HIV epidemic. This triggered an interest in further study of Immunology.

Dr. Petrak completed an Allergy and Immunology Fellowship at the New York Hospital/ Cornell Medical Center. She is board certified in Allergy and Immunology, as well as Internal Medicine. She is a Fellow of the American Academy of Allergy, Asthma and Immunology and a member of the American College of Allergy & Immunology. She is also a member of the American Headache Society, Colorado Medical Society and the Colorado Asthma and Allergy Society.

Dr. Petrak has been practicing in Boulder county since 1999. She enjoys problem solving and finding the best individual treatment plan for each problem. Dr. Petrak has a special interest in asthma diagnosis and management; headache management; how headaches and allergies interact; food allergies; drug sensitivities; and the composition of dust in Boulder County, especially regarding pet allergens.

After being awarded a research grant from The American Academy of Allergy and Immunology, Dr. Petrak established an Immunology Lab in Boulder to study the concept of hypoallergenic dog breeds and amount of allergenic protein secretion in individual dogs.

Dr. Petrak loved growing up in New York City and training in New York with access to a variety of medical and scientific expertise. In Colorado she enjoys her career, her family,
her dog, as well as hiking, cycling, skiing, exploring the mountains and deserts, and being outdoors as much as possible. Her professional goal is to enable as many people as possible to enjoy the outdoors, their foods, and their pets.
