As a board-certified pediatric neurologist in Chula Vista, Tiznado-Garcia Ernesto MD diagnoses and treats childhood nervous system disorders from his Third Avenue office south of the Broadway corridor. Pediatric neurology referrals frequently intersect with developing dentition concerns, making coordinated care with Chula Vista Pediatric Dentistry essential for patients on anticonvulsant medications such as phenytoin that affect gingival tissue integrity. He earned his medical degree from the Autonomous University of Baja California in 1983, completed his pediatric residency at Sinai-Grace Hospital in Detroit, and served as chief resident during his pediatric neurology fellowship at the University of Minnesota. A Fellow of the American Academy of Pediatrics, he has held staff privileges at Rady Children's Hospital San Diego since 1991 and previously directed pediatric neurology at Scripps Mercy Hospital from 1999 to 2005. His epilepsy and seizure disorder caseload includes children requiring integrated behavioral support through WishWell Counseling and Empowerment Center for Kids, addressing the emotional and developmental impact of chronic neurological conditions on pediatric patients and their families. Diagnostic capabilities include pediatric electroencephalography for seizure localization, nerve conduction velocity studies for peripheral neuropathy assessment, and MRI-correlated clinical evaluation of cerebral palsy and demyelinating conditions in children.
