Mary V. Lasley, MD

**Dr. Lasley retired at the end of July 2022, but still offers a limited number of telemedicine visits.   Please read her farewell letter.  Our practice greatly appreciates Dr. Lasley’s service to Northwest Asthma & Allergy Center and wishes her all the best. If you are a patient of Dr. Lasley, our staff can help you find another provider to maintain your excellent medical care.

Dr. Lasley is board-certified in both Allergy and Immunology and Pediatrics. After receiving her medical degree from the University of Nebraska Medical Center in Omaha, she completed her pediatric training and a fellowship in Allergy and Immunology in 1995 at the Medical College of Wisconsin in Milwaukee. She currently holds a Clinical Professor position with the Department of Pediatrics at the University of Washington.

Dr. Lasley enjoys hiking, baking, taking cooking lessons, and walking her misbehaved Welsh terrier. She hates garden work, especially weeding. Now that her sons are grown, and she is not attending their sporting events, she and her husband attend Husky Football games (even though neither are UW Alums). She enjoys solving puzzles and finds that being an allergist gives her an opportunity to listen carefully to patients and their families and work together to create a plan.   

She says, “Good medicine starts with good listening. I am honored when patients and their families put their trust in my care. One of the aspects I cherish most about being an allergist is the close, ongoing relationship I have with my patients and their families.”
