Pediatric Dentist, U.S. Army Veteran, & Global Health Advocate
Dr. Andrew Vo is a compassionate and highly skilled pediatric dentist whose career is built on a foundation of service, education, and a deep passion for improving children's oral health. With extensive experience in treating children of all needs, including those with special needs, autism, and dental anxiety, Dr. Vo is committed to providing exceptional care tailored to each child’s unique situation.
A Strong Educational Foundation
Dr. Vo’s journey in dentistry began at the University of Southern California (USC), where he graduated with his Doctorate of Dental Surgery (DDS) in 2015. His desire to further expand his expertise led him to complete an Advanced Education in General Dentistry (AEGD) in 2016, where he gained valuable experience working with diverse patient populations. However, his true calling was pediatric dentistry, which led him to pursue further specialization.
In 2019, Dr. Vo completed his Master of Dental Science (MS) and a Pediatric Dentistry Certificate at Nationwide Children’s Hospital and The Ohio State University. During his residency, Dr. Vo not only mastered pediatric dental procedures but also specialized in the care of children with complex medical needs, including special needs and autism. As Chief Resident, Dr. Vo demonstrated exceptional leadership, mentoring fellow residents and working closely with multidisciplinary teams to provide comprehensive care for children who required extra support.
Specialized Skills in Pediatric Dentistry
Dr. Vo’s training and expertise go beyond general pediatric dentistry, equipping him with the unique skills necessary to care for children with a wide range of needs:
Special Needs Dentistry: Dr. Vo is highly trained in managing children with special needs, including those with physical or developmental disabilities. His experience enables him to offer tailored treatment plans, ensuring children with varying abilities feel comfortable and well-cared for during their dental visits.
Autism Spectrum Disorder (ASD): Having worked with many children on the autism spectrum, Dr. Vo understands the challenges these children may face when visiting the dentist. His approach is patient and empathetic, using techniques like visual aids, social stories, and sensory-friendly practices to make the dental experience more comfortable for children with autism.

Dr. Vo employs a gentle, child-friendly approach to make dental visits as enjoyable and anxiety-free as possible.

With over ten years of clinical experience, she has earned a reputation for combining exceptional technical skill with genuine warmth, creating a dental experience where children feel understood, empowered, and excited to care for their smiles.
A triple USC Trojan, Dr. Trishia earned her bachelor’s degree, Doctor of Dental Surgery (DDS), and Advanced Pediatric Dentistry Certificate from the Herman Ostrow School of Dentistry of USC. Her academic excellence and dedication to mentorship led her to return as a clinical instructor, where she trained dental students and pediatric residents in evidence-based, prevention-focused dentistry. She found deep fulfillment in helping young clinicians cultivate the same compassion, patience, and attention to detail that define her own practice philosophy.
During her pediatric residency, Dr. Trishia spent extensive time at the Children’s Hospital of Orange County (CHOC), where she cared for medically complex and special-needs children. These experiences profoundly shaped her approach to pediatric dentistry, teaching her that successful care begins with empathy, communication, and an unwavering commitment to treating each child as an individual. She learned that dentistry, at its best, is not only about restoring teeth—it’s about nurturing confidence, health, and trust that lasts a lifetime.
Dr. Trishia is known for her conservative and minimally invasive philosophy, focusing on prevention, early intervention, and collaboration. She believes that the best dentistry is gentle, intentional, and rooted in understanding a child’s overall development—not just their dental chart. By prioritizing preventive care and patient education, she helps families create healthy habits that extend far beyond the dental chair. Parents often comment on her ability to explain treatment options in a calm, reassuring way that makes even complex topics feel approachable and clear.
Her advanced training in airway-focused pediatric care and tongue-tie (frenectomy) management has made her a trusted resource for families seeking answers to challenges related to feeding, speech, and sleep. She takes a whole-child approach to oral health, recognizing that the mouth serves as a gateway to breathing, nutrition, and overall wellness. By addressing airway development and oral function early in life, Dr. Trishia helps set the stage for lifelong healthy growth. She works closely with a multidisciplinary team—including lactation consultants, myofunctional therapists, speech-language pathologists, and pediatricians—to ensure her patients receive thoughtful, coordinated care tailored to their unique needs.
Dr. Trishia’s dedication to excellence extends beyond her clinical work. She is an active member of the American Academy of Pediatric Dentistry (AAPD) and maintains certification with the American Board of Pediatric Dentistry (ABPD). Through continuing education and professional collaboration, she remains at the forefront of the latest advancements in airway development, growth guidance, and minimally invasive pediatric dentistry. Her peers and patients alike describe her as meticulous, intuitive, and endlessly kind—a doctor who leads with both heart and science.
At the heart of her work is her belief that dentistry should feel safe, joyful, and empowering. She loves turning first visits into fun adventures, transforming nervous children into confident dental pros who look forward to coming back. Every patient encounter is a chance for her to build trust, celebrate small victories, and plant the seeds for a lifetime of healthy smiles.
In her free time, you’ll find Dr. Trish exploring new restaurants with her husband (who is also a dentist), running, practicing yoga, and spending quality time with her two sons. She embraces balance and mindfulness in her personal life—the same qualities she brings into her practice every day. Whether she’s teaching a young patient how to brush like a superhero, guiding a new parent through tongue-tie recovery, or chasing Maverick through the park, her joyful energy, patience, and compassion shine through in everything she does.
Dr. Trishia Johnson’s blend of advanced training, gentle communication, and deep commitment to children’s health makes her a trusted partner to families and a valued member of the Tiny Tooth Co. team. Her goal is simple yet profound: to ensure every child leaves the office not only with a healthy smile—but with a heart full of confidence and joy.
