Meet the team


Dr. Sandra Mbibi (DDS)


Dr. Sandra  Mbibi attended The University of  Minnesota where she completed her Degree in Human Physiology. She then attended the prestigious Columbia University School of Dental Medicine where she earned the degree of Doctor of Dental Surgery. After a three-week trip to Cambodia where she had the privilege of treating kids in rural parts of the country, including orphanages, Dr. Mbibi truly realized her passion for Pediatric Dentistry. Shortly after dental school she completed a two-year fellowship in Pediatric Dentistry including special needs care at Brookdale Hospital in New York.

Dr. Mbibi is very passionate about catering to children and providing healthy smiles throughout their childhood. There is nothing more rewarding, engaging, and interesting than working with kids as every child comes with their own unique personality. She considers it a privilege and a responsibility to provide the best dental care to each patient and their families.       

Dr. Mbibi continues to keep up with the latest innovations in pediatric dentistry. She is committed to continuing her education with additional formal training in order to offer the best possible treatment options for your child. These include treatments such as Laser dentistry, sedation dentistry, interceptive orthodontics, and the latest technology in low radiation x-rays.

In her spare time, Dr. Mbibi enjoys spending time with friends and family, exploring various restaurants in Houston, traveling, and reading.


Dr. Chun Yin Wong (DMD)


Dr. Chun Yin Wong earned a Doctor of Dental Medicine degree from University of Nevada Las Vegas School of Dental Medicine (UNLV) and a Bachelor of Science in Biology with magna cum laude honors from the University of Nevada Las Vegas.

At UNLV School of Dental medicine, Dr. Wong was inducted into the honorary Omicron Kappa Upsilon, and graduated magna cum laude as Salutatorian. During his dental school training, he discovered his passion for working with children and patients with special needs through extensive and numerous externships at the Children’s Hospital. He went on to complete his pediatric dental residency program at Temple University Hospital in Philadelphia, Pennsylvania. During his time there he had extensive specialized training in advanced behavior management techniques such as oral conscious sedation and hospital dentistry.

Dr. Wong is highly experienced at performing frenectomies to patients of all ages, including babies. He takes great pride in seeing the improvement in latching, feeding, enunciating words, and general improvement on quality of life afterward. In retrospect, Dr. Wong didn’t receive his lingual frenectomy until he was an adult and wishes he had the knowledge he has now to get it done when he was younger.

A recent transplant to the Houston area, Dr. Wong previously lived in Las Vegas, Nevada for many years having moved there with his family from Hong Kong when he was 10 years old. During his free time, he loves to spend time with his family, travel different parts of the world, and explore nature.
