About Dr. Michael O'Brien

While I am originally from Saint Louis, MO I have now made San Diego my new home. I am a proud Trojan and graduated from the University of Southern California School of Dentistry, a program renowned for clinical excellence in restorative dentistry. After graduating from USCSD in 2008, I returned to Saint Louis where I practice for four years primarily at two small private practices before moving back out west to San Diego in 2013. I am currently licensed to practice in both the state of California and the state of Missouri.

Simply put, I am passionate about dentistry. I love working with my hands and helping people though both education and high quality dentistry that mimics nature. I am constantly reading and researching dental literature to continuously update my dental knowledge. I am a member of the San Diego Advanced Study Group which is part of the Seattle Study Club, a well known and well respected dental study club. When living in Saint Louis, I was a member of two different study groups: the Young Dentist Study Club and the Oral Surgery Study Club. I am dedicated to the craft of dentistry and committed to providing clear treatment options in simple terms and consistently excellent results. While I am a Saint Louis native, I love living here. In my spare time I enjoy fishing, playing with my dog, welding or working on my most recent project, and I am an avid home brewer.
