About Katherine M. Masaki, DDS MS
Long-term, stable results and a treatment plan that avoided surgery for one patient are notable themes here, especially among adult patients.
Reviews here point most often to results that hold up well after treatment, including one patient whose teeth stayed straight nine years later, and to an orthodontist described as thorough and detail-oriented in planning treatment. Several reviews mention a plan that corrected an overbite and overcrowded teeth without surgery, after other orthodontists had proposed more extensive work. The office itself comes up as clean and equipped with newer technology, and a number of reviewers are adults rather than only younger patients.

Dr. Masaki’s orthodontic practice is outstanding! The professionalism and expertise of Dr. Masaki are evident, as she thoroughly explained all options, ensuring we understood every step. The practice is impeccably clean and welcoming, with a friendly and professional staff that makes every visit enjoyable. They excel at creating a comfortable atmosphere for young patients, like my 9-year-old daughter. Communication is seamless, with prompt responses to any questions. We highly recommend Dr. Masaki and her team for exceptional orthodontic care!

Dr. Masaki is a honest hard working orthodontist. I met with 4 other orthodontists prior to her and everyone laid out extensive and very expensive treatment plans for my slightly crooked teeth. Dr. Masaki gave me a straight forward plan that made sense to me. I expressed to her all of the other orthodontists concerns and she said she can fix my issues without surgery. In 18 months my braces were off and now 9 years later my teeth are still straight without problems. I remember her appointments having little wait times and her high attention to detail made me comfortable about the progress of my treatment. Thank you so much Dr.Masaki!
