Leslie Sauer, MD practices pediatric medicine at Sharp Rees-Stealy in La Mesa from the fifth floor of the Grossmont Center Drive campus, bringing board certification through a Kaiser Permanente Southern California residency. Well-child visits from infancy through adolescence incorporate the AAP Bright Futures preventive-care framework, linking immunization tracking, nutrition counseling, and oral-health screening to the pediatric dental pathway anchored by Allison Avenue Dental in La Mesa. A Nova Southeastern University College of Osteopathic Medicine graduate with over twenty years of clinical experience, the physician applies osteopathic diagnostic principles to pediatric musculoskeletal assessments, identifying structural asymmetries during routine physical examinations. The practice addresses upper respiratory infections, allergic rhinitis, bronchial asthma, eczema, and recurrent otitis media—conditions that collectively represent the highest-volume pediatric complaint categories in the La Mesa 91942 ZIP code. Same-building prescription fulfillment through Sharp Rees-Stealy La Mesa Pharmacy reduces the turnaround between diagnosis and first-dose administration for acute pediatric infections requiring immediate antibiotic therapy. Highest-acuity evaluations include febrile seizure assessment protocols, post-concussion return-to-play clearance using Zurich consensus guidelines, and rapid-onset wheezing intervention with in-office peak-flow monitoring and nebulizer delivery.
