Company History
Cardiology Physicians, P.A., established in Daytona Beach during the 1970s, is recognized as one of the oldest cardiology groups in Volusia County. Over the decades, it has earned a reputation as a pioneering practice — notably being the first group in the region to perform pacemaker implantation procedures.
The practice's founding members included distinguished cardiologists such as Dr. David Henderson, and now retired members Dr. Irwin Lieder, Dr. James Carley, Dr. John Walker, and Dr. Richard Arnold.
Today, Dr. David Henderson serves as President and remains a key figurehead, bridging the practice’s early roots with its continued presence in the community. Although serving patients since the 1970s, the practice was formally incorporated on February 1, 1982, under the name Cardiology Physicians, P.A., located at 305 Memorial Medical Parkway, Suite 301, Daytona Beach. As of 2025, the company remains active with a management team composed of Dr. Henderson (President), Dr. Dinesh Arab (Vice President), and Dr. Humayun A. Jamidar (Treasurer).
The practice operates from two primary locations within Daytona Beach:
Halifax Location
311 N. Clyde Morris Blvd., Suite 320 — housed in the Halifax Hospital Lohman Building
Memorial Location
103 Memorial Medical Parkway, Suite 200 — situated in the Florida Hospital Professional Building
Both sites continue to offer comprehensive cardiovascular services, including consultations, diagnostic testing, interventional procedures, and preventive cardiology. At the Halifax location, physicians include Dr. Humayun A. Jamidar and Dr. Otakar Quadrat, supported by nurse practitioners April Shadeed, Sierra Stamper, and Misty Pennington
