Meet Dr. Sarah Kim, D.D.S.

Warm, attentive, and deeply committed to her patients, Dr. Sarah Kim brings a thoughtful and gentle approach to dentistry. She received her Doctor of Dental Surgery degree from the University of Texas Health Science Center at San Antonio, widely recognized as one of the nation’s top dental schools. With active dental licenses in California and New Mexico, she is proud to care for families and individuals throughout the Union City community.

Dr. Kim’s philosophy blends thorough, attentive dental care with a gentle touch. We believe in doing the basics exceptionally well — from preventive care to everyday treatments — and creating a positive experience where you feel relaxed and confident in your dental decisions. Her philosophy centers on conservative dentistry—prioritizing long-term oral health, comfort, and personalized treatment plans for every patient.

When she’s not caring for patients, Dr. Kim can be found running trails, exploring new hiking spots, or spending time outdoors. She loves building lasting relationships and creating an environment where every patient feels safe, supported, and confident in their smile.

What Our Patients Say

“Associates and Dr. Sarah Kim were very thorough and did an excellent and gentle job. What impressed me was that they made no effort to “upsell” on additional expensive services! I’ve had that so often with other dental practices.”
“I love my new dentist Dr. Sarah… she explains very thoroughly the procedures and whats next in the process… I highly recommend her… You are AWESOME!!”
