Dr. Paolo Zizzo D.O. in Carlsbad's Poinsettia corridor holds board certification in internal medicine, serving adult and geriatric patients from a solo practice on Avenida Encinas near Poinsettia Park. His geriatric-medicine scope addresses fall-risk evaluation, polypharmacy management, and chronic-disease coordination that parallels the in-home care models offered by Archer Health Inc. A 1994 graduate of Western University of Health Sciences (College of Osteopathic Medicine of the Pacific), he completed his internal-medicine residency at Alameda Health System's Highland Hospital and maintains privileges at Palomar Medical Center. Bilingual consultations in English and Spanish support medication reconciliation, osteoporosis screening, and cardiovascular-risk assessment across a diverse North County patient population. Prescription management for complex multi-system conditions benefits from proximity to compounding and delivery services at Carlsbad Neighborhood Pharmacy. Highest-acuity services include hypotension differential workup, diabetic macrovascular-disease staging, and pressure-injury classification under the National Pressure Injury Advisory Panel framework.
