“It’s not enough for me to just find a medication that works for people’s medical problems,” he says. “I want to get patients to their potentially life-altering intervention, but that is not enough. To really help people, you must get to the root of the problem, which is often not solved by medication or an intervention.”

As one who is literally driven by matters of the heart, Dr. Yiachos seems tailor-made for this medical specialty.
