Dr. LaJuan Hall DDS MS


Children are such precious gifts, and I feel lucky to use my skills in mentoring, empathy, patience, and knowledge in dental care just for them. My life as a pediatric dentist has allowed me to interact with children from toddlers to teenagers. I aim to help kids and guide families to achieve the best oral health for a lifetime.

I earned a Doctor of Dental Surgery and a Master of Science in Oral Biology from the University of California San Francisco. My dedication to patient care led me to an in-hospital pediatric dental residency program at UCSF Benioff Children’s Hospital Oakland. I was honored to serve as Chief Resident. The hospital-based residency prepared me for managing dental traumas, medical emergencies, and sedation dentistry.

On a professional level, I enjoy serving as a leader with local, state, and national organizations promoting and advocating for pediatric oral health. My professional affiliations include the American Academy of Pediatric Dentistry, California Society of Pediatric Dentistry, American Dental Association, California Dental Association, and three dental honors organizations. I am an active member of the National Association of Corporate Directors member, serving as Section Chair for the American College of Dentists and the Audit Chair of the California Dental Association Foundation. In recognition of my contributions to the dental profession, I am grateful to have received the UCSF Dental Alumni Medal of Honor in 2023.

In my spare time, I love spending time with my amazing 3-year-old granddaughter, who brightens my life and keeps me smiling. I am super excited to join the dynamic team at Hopscotch Children’s Dentistry, and I’m eager to meet all the unique patients and help them create their beautiful smiles.
