Greg Halliday, PA-C specializes in cardiology at Intermountain Health’s Cache Valley Heart Clinic in Logan, Utah. He supports patients in Cache County, Rich County, Box Elder County, southeastern Idaho, and surrounding communities, with clinical interest in coronary artery disease, various heart failure states, and arrhythmia management. He enjoys treating patients with coronary artery disease and cardiomyopathy/HFrEF, because he finds it rewarding to see significant improvement in symptoms with excellent medical therapy and lifestyle modification.

He believes in treating each patient as a whole person, not just a diagnosis, and in fostering open communication so they feel informed and respected. His goal is to provide evidence-based, timely interventions while maintaining empathy and trust, ensuring that every patient receives the same level of care he would want for his own family.

Greg has been a physician assistant …since 2004, beginning on the Navajo Indian Reservation, where he learned the importance of listening deeply and caring for patients from diverse backgrounds. Over the years, he’s developed a patient-centered approach that blends technical expertise with compassion. Greg values clear communication, so his patients understand their condition, their options, and the reasoning behind each step of care. His goal is to provide the high quality evidence-based treatment while helping every patient feel respected and supported.

Originally from North Ogden, Utah, Greg enjoys life with his wonderful spouse and two boys who are just as wonderful. They love mountain biking and helping coach the local NICA team. He also enjoys visiting National Parks, camping in the family trailer, reading both fiction and nonfiction, and caring for their pets.
