Legacy Heart Center is committed to keeping your heart healthy and strong. It's what our patients and referring physicians have come to expect from the cardiologists and staff at Legacy Heart Center.
We trace our roots to the early 80's when two of our original partners, Dr. Waenard Miller and Dr. David A. Schwartz, began practicing together in Collin County.
Today Legacy Heart Center includes 15 cardiologists and more than 100 other health and administrative professionals providing cardiovascular care to our patients in a state-of-the-art facility in Plano with the most comprehensive array of cardiac diagnostic testing and treatment services available in the area.
With offices in McKinney, we are able to provide convenient access to cardiovascular care to patients from all parts of Collin County including Plano, Frisco, Prosper, Celina, Allen and McKinney.
Our cardiologists are on staff at Baylor Regional Medical Center at Plano, The Heart Hospital Baylor Plano, Texas Health Presbyterian-Plano and Medical Center of McKinney.
We are the only private cardiology practice with fully certified nuclear, echocardiography, and computed tomography labs located in Collin County. The nuclear lab is certified by the Intersocietal Commission for the Accreditation of Nuclear Laboratories (ICANL), the echo lab is certified by the Intersocietal Commission for the Accreditation of Echocardiography Laboratories (ICAEL), and the Computed Tomography lab is certified by Intersocietal Commission for the Accreditation of Computed Tomography Laboratories (ICACTL).
