Brandon Larkin, DDS
Board Certified Pediatric Dentist

Dr. Larkin has been a practicing pediatric dentist since 2014. He enjoys building relationships with patients and their families to promote a lifetime of good oral health. Believing that education is the best prevention, he emphasizes preventative routines and treatment.
Dr. Larkin was born and raised in Flint, Michigan. Dr. Larkin developed a passion for working with his hands by doing carpentry work with his father at an early age. In college, he found that dentistry provided an opportunity to apply that passion while impacting the lives of others. Dr. Larkin graduated from the University of Michigan with a Bachelor of Science degree in Brain Behavior and Cognitive Neuroscience. He graduated from the University of Michigan School of Dentistry with a Doctorate of Dental Surgery. Dr. Larkin then pursued specialized training in Pediatric Dentistry at Miami Children’s Hospital. His training focused on providing dental care to children, teens, and patients with special healthcare needs. He has extensive training in dental trauma, craniofacial abnormalities and conscious sedation.
Dr. Larkin is currently a member of the American Academy of Pediatric Dentistry, the Florida Academy of Pediatric Dentistry and the Florida Dental Association. He has also been a member of the craniofacial teams at Miami Children’s Hospital and Johns Hopkins All Children’s Hospital. He has presented research at the American Academy of Pediatric Dentistry and the American Academy of Pediatrics. In addition, his research has been accepted for publication in Pediatrics, a leading journal for pediatricians.
Dr. Larkin understands that going to the dentist can be a fearful experience and thus strives to create a fun, safe, and trusting environment. He encourages parents to be involved in developing care plans for their children and welcomes them to the treatment area. In his free time Dr. Larkin enjoys college football, the beach, and spending time with his wife and their two sons.
