Manuel Castillo, DDS
Board Certified Pediatric Dentist



Lourdes Colon

The first thing you’ll notice about Lulu is her big, easy smile. She’s married and has two children. Originally from Puerto Rico, she has been in San Antonio since 2015. She earned her Business Administration degree in Puerto Rico, after which she worked in the dental field starting in the front office, then as a dental assistant and finally as office manager —all adding up over 20 years of experience. Once she arrived in San Antonio, she went back to school and became a Registered Dental Assistant. She loves working in the dental field, and especially with children. For her, children are pure joy, love, and fun. In her free time, she enjoys music, dancing, cooking and doing crafts. Working at Happy suits her well as she expresses her love for the little ones, helps them to trust the dentist, and will do everything possible to make your child’s visit a happy one.


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.
