About Liz O'Connor, APRN

As a Cardiovascular Nurse Practitioner, I have spent the majority of my 37 years in the healthcare field practicing in cardiology. I have a vast array of experience in evaluating and treating patients with a variety of cardiac and vascular conditions in collaboration with Cardiologists.

Through my career, I have gained invaluable knowledge, education and hands-on experience with both inpatient and outpatient follow-ups, stress testing, coumadin management, among many other duties.

When I’m not at work, I enjoy spending time with both family and friends, reading murder mysteries and singing with the Great Falls Symphonic Choir.
