Marian Martin, MD - Sharp Rees-Stealy Santee is a board-certified pediatrician accepting new patients on the second floor of the Cuyamaca Street campus, where Sharp's 1923-founded multispecialty network consolidates pediatric and specialty care under one roof. Her evidence-based practice emphasizes preventive medicine — structured well-child visits, catch-up immunization schedules, and adolescent wellness screenings — with same-day acute-illness slots for fever, ear infections, and respiratory symptoms triaged through Perlman Clinic Santee on Mission Gorge Road when after-hours care is needed. Dr. Martin serves families across Santee, El Cajon, Lakeside, and La Mesa within the Sharp Rees-Stealy network of 22 locations and more than 580 affiliated physicians. Newborn hearing assessments and speech-delay evaluations at well-child intervals connect to audiology resources at Superior Ear Works on Cuyamaca Street for diagnostic audiometric testing when screening results warrant further workup. Advanced pediatric assessments include structured developmental surveillance using validated ASQ-3 questionnaires, Edinburgh Postnatal Depression Screen administration for new mothers during infant visits, and peak-flow spirometry for pediatric asthma classification in children five and older.
