Scott E. Shapiro, MD, FACC

Past President Pennsylvania Medical Society
Board Certified Cardiologist CEO/Executive
CMO/Founder

Dr. Shapiro began moonlighting during his third year of residency to secure additional income while maintaining the flexibility required for his training program. His exposure to staffing agencies revealed a common practice of treating physicians as mere CVs, lacking personal attention.

As a staunch advocate for providing physicians and clinicians with opportunities for supplemental income, experience enrichment, network expansion, work-life balance and control over their schedules, Dr. Shapiro founded OnCall Solutions 20 years ago. OnCall Solutions proudly provides an elevated experience in staffing and recruiting through our distinguished group of Board-Certified Chief Medical Officers. These professionals collaborate with you, offering peer support and guidance throughout your journey, ensuring a unique and supportive experience. With a mission of providing the best opportunities to pursue the desired clinical experiences, maximize financial opportunities, and optimize lifestyle preferences, Dr. Shapiro has grown OnCall Solutions from one state, to offering job opportunities nationwide.

Scott has been married to his wife Marci for 24 years. They have three daughters and a miniature goldendoodle. Scott and his family love to ski, spend summer weekends at the Jersey Shore, and are big fans of their Philadelphia sports teams.
