Lee J. Cowles, DMD

drCowles Born and raised in Parkrose, Dr. Lee Cowles loves serving this beautiful Portland community just as his father did. Dr. Cowles attended Brigham Young University, where he completed his undergraduate studies, switching from a piano/music major to pre-dentistry after serving a two-year LDS mission in Missouri and Iowa. Following his undergrad, Dr. Cowles attended the Oregon Health Sciences University (OHSU) School of Dentistry, where he graduated with his DMD.

Dr. Cowles loves being a general dentist because of his patients, whom he considers to be his friends and adopted family. He strives to provide his patients with comprehensive dental care so they don’t have to go to an unfamiliar specialist on a tight schedule. Being a dental wimp himself, Dr. Cowles always empathizes with his scared or concerned patients. He focuses on listening and communicating with all of his patients, whether they’re in for a toothache or a smile makeover.

Another reason Dr. Cowles loves dentistry is because it’s a field that requires continual learning and mastering of the latest technological skills. For over 25 years, he has been a member and former President of the Jacobson’s Dental Research group at OHSU. Dr. Cowles spends many hours each year in continuing education courses to learn the latest techniques to deliver the highest-quality, comprehensive dental care.

When not at the office, Dr. Cowles enjoys spending time with his wife, Leila, and their five children, as well as going camping, playing racquetball, and doing family history research. About twenty years ago, Dr. Cowles’s sons acquired an interest in rocks and minerals. This interest led Dr. Cowles to develop a love for creating and making gemstone trees, which he has sold locally and around the world.
