Meet Our Team

South Valley Children’s Dentistry & Orthodontics has pediatric dental specialists on staff overseeing our dental operations. Pediatric dentists are children’s dentists who elect to take an extra two years of schooling to specialize in pediatric dentistry. Our children’s dentists work with children aged nine months to 18 years, and with special needs patients up to 26 years. No matter how minor or serious your child’s needs are, we have the knowledge and technology upon which you can rely.
