Trinity Heart and Vascular Group is a cash-based, direct pay, third party free, outpatient cardiology practice. We diagnose and treat a comprehensive array of cardiac conditions including evaluation of patients with known or suspected peripheral vascular disease.

Our cash-based approach allows us to offer affordable, transparent pricing for our services. Budget friendly fees are especially advantageous for patients who are self-pay (self-insured) or have a high deductible insurance plan.

Being ‘third party free’ minimizes outside intrusion into the patient care paradigm. This positively fosters the patient-provider relationship and gives our clients confidence that we are solely dedicated to their particular medical needs with no undue influence by insurance companies, corporate medical systems or the government.
