Pediatric and lifestyle medicine services at Sharp Rees-Stealy La Mesa come from Cherie G. Chu, MD, a board-certified pediatrician practicing since 2005 from the fifth floor of the Grossmont Center Drive campus. The pediatric panel spans newborn through adolescent care with behavioral health integration, routing complex cases to psychiatric and counseling resources including Alvarado Parkway Institute Behavioral Health System Outpatient Services for structured intervention programs. UC Irvine College of Medicine provided the medical degree, and Sharp's Climate and Planetary Health Committee membership reflects the physician's engagement with environmental determinants of pediatric disease, including asthma triggers and heat-related illness prevention. Bilingual English-Spanish consultations serve La Mesa's linguistically diverse pediatric population, with video and phone visit options extending access to families unable to reach the Grossmont Center Drive location. Pediatric oral surgery and complex dental referrals coordinate with specialists including Allen Wei DDS for procedures requiring sedation-age assessment and post-operative pediatric monitoring. The practice specializes in lifestyle medicine implementation during the first five years of life, applying the six-pillar framework — plant-predominant nutrition, physical activity, sleep optimization, stress management, social connection, and substance avoidance — as published in peer-reviewed developmental pediatrics literature.
