About
At Trinity Heart and Vascular Group, Dr. Daniel O'Roark delivers direct-pay cardiovascular care across two northeast Tennessee locations. The Greeneville office serves as the main hub, with a second location in Johnson City. The practice holds the distinction of being the first third-party-free cardiology practice in the region.
Dr. O'Roark built the practice around four core values: compassion, integrity, transparency, and respect. The practice posts all pricing publicly and patients pay a single flat rate at the time of service. Initial evaluations run approximately 60 minutes. Appointments typically happen within days rather than weeks. The practice treats a broad range of cardiovascular conditions, from atrial fibrillation and coronary artery disease to valvular disease and peripheral arterial disease. It also offers cardiac risk assessments for athletes and children starting at age six.
