Rajnish Kooner, DO brings dual emergency and family medicine training to the Grossmont Medical Plaza on Grossmont Center Drive in La Mesa, practicing through the Sharp Rees-Stealy Medical Group. The osteopathic approach integrates musculoskeletal assessment into acute-care triage, a diagnostic framework that complements the spinal adjustment and rehabilitation protocols at nearby practices like San Diego Chiropractic Doctors in La Mesa. A College of Osteopathic Medicine of the Pacific graduate (1998) who completed family medicine residency at Adventist Health Glendale (1998–2001), the physician holds California medical license 20A7424 and NPI 1255343737. The practice's family medicine scope handles chronic disease management, preventive screening, and acute illness evaluation under one roof, with laboratory orders processed through the Grossmont Medical Plaza's on-site lab and specialty referrals coordinated with campus eye care providers like Grossmont Vision Center Optometry. Emergency presentations requiring advanced intervention transfer directly to Sharp Grossmont Hospital's emergency department, located on the same Grossmont Center Drive campus.
