Arroyo Grande Specialty Center - Coastal Cardiology
Dignity Health Coastal Cardiology’s team of board-certified physicians has been serving the Central Coast’s cardiovascular needs for more than forty years. Our mission, providing the best cardiac care possible to each and every patient, has stayed the same since 1986. Two accredited onsite labs — echocardiography and nuclear cardiology — are available for the convenience of our patients and referring physicians.
We have Coastal Cardiology locations in San Luis Obispo, Templeton and Arroyo Grande. The San Luis Obispo office is also where our Diagnostic Center is located.
*Note - This location in the Matthew Will Memorial Medical Center Building in Arroyo Grande is the new Arroyo Grande Location for Coastal Cardiology. The providers no longer see patients in its office on Halcyon.
