Dr Mary Lee Associate Dentist at Cooley SmilesDr. Mary Lee
Dr. Mary Lee grew up in Tacoma, Washington, and attended college in California. After graduating from Tufts University School of Dental Medicine in Boston, she returned to Northern California to complete an Advanced Education in General Dentistry residency program. Then she practiced in the Sacramento area for about six years. Her love for the Pacific Northwest led her and her husband to find a new home in the Seattle area, and she joined the Cooley Smiles team in 2017.

One of the most fulfilling aspects of her dental career has been the opportunity to volunteer her skills to treat underserved patients at free care clinics with non-profit organizations like the Adventist Medical Evangelism Network. Dedicated to providing patient-centered care, Dr. Mary believes that building relationships with her patients and enhancing their smiles and oral health are the most rewarding aspects of dentistry. In addition to dentistry, she enjoys working out, yoga, golfing, and traveling.
