Sara Cancel

Mrs. Cancel is the happy mother of a handsome boy. She is originally from Puerto Rico, where she went to Art School and Dental Assisting School. She moved to San Antonio with her husband in 2014. She loves working in dentistry. Her motto is to always give her best. In her free time, Mrs. Sara enjoys painting and singing. At Happy Pediatric Dentistry, we all like her sweet, happy and caring disposition. She is grateful for her parents as they taught her to be respectful towards others and she always wishes the very best for them.


We understand that parents, at times, are unable to take care of their children’s dental needs during regular business hours. That’s why we are happy to offer services on Saturday morning and have an extended day on Wednesday until 7pm.
