About
Dentist Katy, TX

Dr. Tam Nguyen
Board Certified Pediatric Dentist
Dr. Nguyen is proud to call Houston her home. She was born and raised in southwest Houston, where she attended DeBakey High School for Health Professions and graduated with a Bachelor’s degree from the University of Texas at Austin (Hook’em Horns!). She obtained her dental degree from Boston University in Boston, MA where she also met her husband, William.
After practicing in Massachusetts, they decided to move back to her hometown of Houston, Texas. Following several years of work as a general dentist in Richmond, Dr. Nguyen realized her passion was to work with kids and she decided to go back to school to specialize in pediatric dentistry.
Dr. Nguyen returned to Boston University to serve her pediatric residency and earn a specialty degree. During the residency program, Dr. Nguyen gained insight and knowledge about treating children as young as 6 months old as well as patients with special needs.
When not in the office, Dr. Nguyen enjoys exploring the diverse food scene Houston offers, working out, and hiking and exploring local and national parks.“My philosophy focuses on promoting healthy lifestyles and oral habits from a young age. By introducing parents and patients to the dentist at an early age, my staff and I are able to guide parents and children as they grow, and build trusting relationships with our families. We provide treatment in a fun, gentle, and relaxing environment and believe in the importance of working together to provide the best treatment for your child.”

Dr. Dave Cho
Dr. Cho grew up in Southern California and attended the University of California, Riverside where he received his Bachelor’s degree in Biochemistry. He considered dentistry while in college, but was offered an opportunity at a pharmaceutical company where he worked for five years. Dentistry was always in the back of his mind and he decided to pursue a career change. This led him to Boston where he obtained his dental degree from Tufts University, and also where he met Dr. Nguyen and Dr. Sung, moved to Houston to be closer to family, and the rest is history!
Dr. Cho enjoys seeing patients of all ages and his favorite part about dentistry is forming lifelong relationships with his patients. His laid back attitude and calm demeanor immediately puts patients at ease. He is experienced in oral sedation, endodontics, oral surgery, implant placement, and cosmetic dentistry. He strives to provide quality dentistry by attending several continuing education courses each year.
Dr. Cho lives in Houston with his wife, Ellie, and their puppy, Mimi. They are first time parents to their newborn daughter, Claudia, and he is a proud #girldad!

Dr. William Sung
General Dentist
For Dr. William Sung, dentistry isn’t just a job – it’s a family business! Dr. Sung’s father and two of his uncles are dentists. Dr. Sung was born and raised in California, and graduated from Pacific Union College in Angwin, California with a B.S. degree. He then went on to receive his dental degree from Tufts University in Boston, Massachusetts. It was in Boston where he met his wife, and after practicing for several years in Massachusetts, she decided to move back to her hometown of Houston, Texas. While he is still acclimating to the humidity, Dr. Sung has come to love and appreciate the friendly people, great food, and diverse culture that Texas has to offer.
Though there are many aspects of dentistry he enjoys, Dr. Sung’s main motivation is helping others. Whether he’s easing pain through a much needed dental procedure, or improving confidence with cosmetic dentistry, with every patient he treats, he is reminded that he’s achieved his lifelong dream of working in healthcare.
Dr. Sung has made a lifelong commitment to learning and keeping up with the evolving field of dentistry by taking several continuing education courses each year. He averages almost 100 hours of CE credits each year, which is over eight times the yearly requirement for a dentist in the state of Texas.
Dr. Sung also holds a Fellowship in the Academy of General Dentistry which is held by only 7% of all general dentists in the State of Texas. To keep up with the latest technologies, procedures, and materials, Dr. Sung is a part of several well known groups and study clubs in an effort to provide the most comprehensive care for his patients.
When he’s not in the office, Dr. Sung can be found exploring nature with his wife. They enjoy hiking and an item on their bucket list is to visit all of the National Parks! Dr. Sung also enjoys scuba diving and is fascinated by the underwater world. Like his fellow Texans, he is an avid sports fan. During basketball and football seasons, he stays busy trying to win his fantasy leagues! As an active member of the community, Dr. Sung actively gives back through volunteer work whenever possible.
