William T. Nguyen, MD

Dr. Nguyen is board-certified in Adult and Pediatric Allergy, Asthma, and Immunology. He attended medical school at the University of Texas Health Science Center at Houston and completed residency/fellowship training at the University of Tennessee – Memphis.

Dr. Nguyen and his family are relocating from Dallas. He brings over 20 years of clinical experience. He has an excellent reputation for providing quality care to his patients and was regularly included in Dallas Magazines’ “Best of” in Allergy and Immunology.

Dr. Nguyen strongly believes that being active is the best way to stay healthy.  He says, “I encourage all my patients to participate or get involved in physical activity. This can be through organized sports, working out, or just spending one day a week walking around the neighborhood.   For me, the best way to maintain an active lifestyle is to set goals for yourself. So, for 2022, I am hoping to summit Mt. Baker. When we get a chance to meet, I would love to hear about your goals and accomplishments.”

Starting June 2022, Dr. Nguyen will be seeing patients in our Renton and Seattle offices.
