Board-certified pediatrician Agnela Isaias, MD, serves Chula Vista's Third Avenue Village medical corridor from 855 Third Avenue, bringing a University of Arizona School of Medicine background to newborn-through-adolescent primary care. The practice handles same-day acute appointments for pediatric fever, ear infection, and respiratory illness, managing cases that — when presenting after scheduled hours — escalate to facilities such as AFC Urgent Care Chula Vista for extended triage. Developmental screening, immunization administration, and well-child exam protocols cover ages zero through 18 across the 91911 ZIP code's family households near the Broadway commercial corridor. Annual vision screening referrals coordinate with Eastlake Optometry for amblyopia detection and pediatric refraction assessments in school-age children. The practice manages complex pediatric asthma cases requiring spirometry-guided controller medication titration, multi-allergen skin-prick testing, and coordinated pulmonology referrals for children with persistent moderate-to-severe airway obstruction.
