Riad Mardoum MD is a pediatrician with Scripps Clinic at 4077 Fifth Ave in Hillcrest, practicing on the Fifth Avenue medical office corridor. Walk-in overflow and same-visit urgent needs from the panel route to Scripps HealthExpress Hillcrest, the system's same-day clinic handling unscheduled pediatric concerns in the same neighborhood. Visit types run from newborn follow-ups and immunization schedules through adolescent sports physicals and school-required screening. Acute pediatric presentations that need inpatient stabilization hand off to Scripps Mercy San Diego Emergency Room, the adjacent full-service ED on the Scripps Mercy campus. The most complex workflow is managing chronic pediatric conditions like asthma or type 1 diabetes through coordinated visits with Scripps specialty clinics and the Rady Children's subspecialty network.
