Dr. Lizzie C. Giangreco, an American Board of Pediatrics diplomate, delivers newborn-focused pediatric care at the Sharp Rees-Stealy La Mesa campus near Sharp Grossmont Hospital. Her UCSD School of Medicine training (class of 1998) included published immunology research on CD4 effector-cell fate, and her current clinical panel concentrates on newborn patients with after-hours acute-care overflow managed through Sharp Grossmont Express Care on the same Grossmont campus. Spanish-language fluency expands her clinical reach to bilingual families across the La Mesa and East County service area. Her practice partnership with a co-physician ensures continuity of care through shared medical records and coordinated treatment protocols within the Sharp Rees-Stealy system. Early dental-health counseling for erupting primary teeth and caries-risk assessment forms a routine component of her well-child protocol, with first-visit timing coordinated alongside La Mesa's A Shop For Smiles - Richard J Hagstrom DDS. Her highest-complexity newborn services include neonatal jaundice management via transcutaneous bilirubinometry and evaluation of congenital cardiac murmurs requiring echocardiographic referral.
