Real Patient Experiences

Patients love our new location just as much as the care they’ve trusted for years:

"Keith is the Jedi Master when it comes to anything about teeth.
I highly recommend I have been going to him since I was born and never had any issues."
Michael Tamir
"I have been going to Keith Marshall for at least 25 years. I have sent many family and friends to him because to me, he is a rare gem in the best possible way.  Kind, smart, and always on the cutting edge of dentistry he honestly cares about each and every patient. Teeth are so important to our health and well-being and I always feel taken care of by him and his fabulous staff....total truth!!!"
K. Rey
"I'm not a fan of going to the dentist due to some not so pleasant experiences at other offices.  This practice has definitely gained my trust. I feel like I am in good, caring hands and the staff are always so friendly and genuine. The hygenist is both personable and extremely proficient yet gentle. She understood my fears and kept me comfortable though my cleaning. I also love the little goodie bags they give you after your cleanings. I highly recommend this practice."
Jeannette Calle
"Have been coming to Dr Marshall since 1979. He’s an incredibly skilled dentist and amazingly gentle one too. I have lived on west coast for years and had much more than average dental work, some done on the west. I now live in Seattle, still come here. (I’m a veterinarian and know excellent dentistry when I see it)
Dr Keith is as good as it gets."
Ron F
"As a long time patient of Dr. Marshall, I can unequivocally say that he is the most personable dentist that I’ve seen, and is someone who cares not only for your dental health, but your health in general. And he recognizes the connection between the two."
Peter R Feuchtwanger
