Dr. Sarah Kim

Dr. Kim received her Bachelors of Science in Biology from Pacific Union College.

This award was given to one student demonstrating integrity, compassion and an interest in patients with special needs.

After graduation, Dr. Kim completed one year of extensive training as a general practice resident at Lincoln hospital, a Level one trauma center located in Bronx, NY.

She then continued her training in pediatric dentistry at St Barnabas Hospital, another level one trauma center, where she served as Chief Resident. Here, Dr. Kim had extensive training in seeing children of all ages, including children with special needs.

Outside of Dentistry, Dr. Kim loves spending time with the loves of her life, her husband and two children. Dr. Kim loves classical music and can often be seen attending violin/cello concerts with her children all around town!


Dr. Christine Min

Dr. Min received her dental degree from University of Iowa College of Dentistry in 2001. Following dental school, she worked at a community health center in Iowa as a dental director, helping underserved children for 8 years. She also served as an adjunct faculty at U of Iowa College of Dentistry, teaching dental students the art of working with children. While working and teaching, she realized her true passion was in treating children.

Dr. Min completed her specialty training in pediatric dentistry at the St. Barnabas Hospital in New York. She was able to treat a wide variety of healthy, trauma, and special needs patients. During her residency, she went on mission trips to Honduras and Laos to provide much needed dental care to children. She was distinguished by being appointed chief resident in her final year.

Pediatric specialty can be challenging and unpredictable, yet absolute full of joyful moments. She feels blessed to share these precious moments with children everyday while positively shaping their dental health from an early age. She brings a light-hearted approach and sense of humor to her work and makes every effort to accommodate each child’s unique personality in a safe, comfortable environment.

She prides herself in providing the highest quality dental care with her caring, easy-going style that helps children and parents feel at ease during their visits. Her goal is to establish a positive dental experience with all patients to foster a healthy, lifelong view of the dental visits. Caring for children has been an important part of her life and there is nothing more rewarding than gaining the trust and appreciation from a young patient.
