VVMC's patients range from healthy adults seeking preventative cardiac care to those with significant cardiac illnesses. Our board certified cardiologists treat cardiac disease with a comprehensive approach that begins with diagnostics and assessments and can include treatments such as blood thinners, electrophysiology (which includes the advanced care for arrhythmias and the use of pacemakers and defibrillators) and/or rehabilitative measures.

While no referral is necessary to book a cardiology appointment, patients are encouraged to contact their insurance company to determine whether a referral is required for optimal insurance coverage. Call (970) 476-1110 for information or to schedule an appointment.
