About Hawthorne Dental

Dr. Keith Watson - Dentist, Owner

Dr. Keith Watson received his Bachelor’s Degree in Science from Penn State University before graduating from the University of Minnesota School of Dentistry in 1998.

Dr. Watson remains committed to continuing education, and he has taken advanced courses in comprehensive care from Spear Education, occlusion and function from the Academy of General Dentistry, and interdisciplinary studies from the Seattle Study Club. He is a member of the American Dental Association, Oregon Dental Association, and Multnomah County Dental Society. 


Dr. Watson is passionate about offering comprehensive care that emphasizes prevention. When treatment is needed, he provides patients with conservative and minimally-invasive dentistry to preserve as much tooth structure as possible. He has also been dedicated to green dentistry and environmentally friendly practices since he started his practice in Portland.



The doctor is originally from the northeast, but he moved to Portland in 2003 after hearing the call of the Pacific Northwest. He appreciates all the city has to offer including the beautiful green spaces and neighborhoods. Dr. Watson enjoys spending time with his wife, Angela, in addition to playing the bass guitar, listening to music, traveling, and having fun outdoors. He also volunteers with Medical Teams International and the Creston School, providing free dental care for at-risk populations in the Portland metro area.

Antonina Robertson, RDH - Dental Hygienist

Antonina was introduced to the dental field as a research assistant at OHSU. After honing her skills as a dental assistant, she completed the Dental Hygiene Program at Clark College in 2015. A vigilant learner, she constantly seeks to broaden her knowledge so she can offer the best care to her patients. She is gentle and thorough, and sets patients at ease with her calmness and positivity.

Born in Tajikistan, Antonina emigrated to the US with her family in 1996, fleeing civil war, floods, and famine. Through persistence and hard work, she was able to master English, complete her prerequisites, and gain acceptance into a respected hygiene program. Now that her studies are over, Antonina is finally allowing herself to pursue other interests such as yoga and gardening. She and her husband Luke reside in Portland's Kenton neighborhood with their cat, Dyevochka.

Green Dentistry - Caring for Our Neighbors and the Environment

Since Dr. Watson started his SE Hawthorne practice in 2005, he has been committed to green dentistry, and each year he and his team expand their repertoire of environmentally friendly practices.

Here is a sampling of what we do:

  • To protect our water supply, all of the metals we remove from your old fillings and crowns are captured in our filters before entering the water system and then saved for environmentally appropriate disposal.
  • To reduce energy consumption, we use compact fluorescent light bulbs throughout the office, and all non-essential equipment is turned off each night.
  • To support renewable energy, we’ve signed up for PGE’s Green Source plan, which ensures that the electricity powering our office comes from renewable sources such as wind and biomass.
  • To reduce waste, we look for creative ways to reuse office products, and purchase recycled products as often as possible.
  • To reduce his carbon footprint, Dr. Watson commutes either by scooter or electric car.

When you’re in for your next visit, rest assured that we’re not only going to deliver great personalized care, but we’re also doing our part for the environment.
