Dr. John Woo - Sebastopol Orthodontics

About Dr. Woo

Dr. Woo was born and raised in Sunnyvale, California. He has been practicing orthodontics in Petaluma and Sebastopol since 1993 and continues to love what he does even after 27+ years! His knowledge of orthodontics and ability to achieve excellent treatment results have earned him much respect in the dental community and with his patients. He has been voted “Best Orthodontist” by the Argus-Courier every year since 2010 and was awarded Diplomate of the American Board of Orthodontics for his proficiency and excellence in the orthodontic field.

When he is not working, Dr. Woo can be found enjoying the Sonoma County lifestyle along with his wife and two children. A lover of sports, he can often be found playing tennis, basketball, golf, skiing or cycling. If Dr. Woo was to have any other job he would be in a band, which has partly inspired his music-themed office! He still enjoys playing the drums and guitar in his free time.

 “ I enjoy practicing orthodontics because it is the artful application of science coupled with the subtleties of patient care. The field of orthodontics is continually evolving and every case is unique.  Therefore, I am given the opportunity to be challenged and creative on an ongoing basis.  The true reward of my work is delivering expert orthodontic care with an unparalleled experience that will leave you smiling on the inside and out!”  – Dr. Woo
