What Patients Say About Our Service...
“I’m glad I did the screening because I found out that I do have some plaque but also a very healthy heart. Dr. Accad has a wonderful gentle manner with patients. He is a clear communicator, explaining the purpose of each test, the process, and later, the results.”
