A History of Excellence


Buena Park Heart Center was founded in 1993 by Dr. Joe Caceres, who sought to create a branch of Caceres Medical Group devoted entirely to his growing base of patients with cardiovascular conditions.  Dr. Caceres places a high value on patient comfort and convenience, and equipped Buena Park Heart Center with state-of-the-art diagnostic equipment, so patients could undergo the necessary testing in a comfortable and welcoming environment.


One Buena Park Heart Center's many advantages lies in is its extensive onsite diagnostic capabilities, including EKG, echocardiogram, stress echocardiogram, ultrasonograms, digital x-rays, and more.  Because we understand the importance of timely and accurate diagnoses, we have invested in the latest diagnostic equipment to perform a wide range of tests without the need for patients to be referred to offsite locations.  Our commitment to equipping our facility with the latest technology is not only more convenient for our patients, but also ensures that we are able to provide the most accurate and reliable results as expediently as possible.​​

Knowledge is also central to our philosophy of care.  To stay up-to-date with the latest medical research and advances, Buena Park Heart Center has a mandatory continuing medical education program (CME) for all providers and staff members.  Through our CME program, our physicians and healthcare professionals have access to the latest medical research and clinical guidelines, allowing them to provide cutting edge care for their patients. The Buena Park Heart Center CME program helps our team to meet the continuing education requirements set by regulatory bodies, and works in tandem with our Clinical Research Department to ensure that our patients receive exemplary care informed by the latest medical guidance.  We are committed to providing the best care possible, and staying informed is a key part of that commitment
