Dr. Kathy Ko

Dr. Kathy Ko is an enthusiastic and caring pediatric dentist who truly believes in creating a positive dental experience for children.

Dr. Ko was born and raised nearby in Cypress, TX. After graduating from Cy-Fair High School, she decided she would like to experience a cooler climate so she moved to Ithaca, NY. There she earned her Bachelor of Science degree in Neurobiology and Behavior from Cornell University. She then attended Boston University where she earned her Doctor of Dental Medicine degree, graduating at the top of her class with Magna Cum Laude honors.

During her time in dental school, Dr. Ko quickly realized how much she loved working with children and that pediatric dentistry was her preferred specialty. She was accepted into the pediatric residency program at the University of Texas Health Science Center in Houston and completed her specialty training at the end of June.

In her spare time, she likes to play the violin with The Medical Center Orchestra, read classic books and try out new restaurants.
