The Benefits of Concierge Medicine and Executive Healthcare
Concierge medicine provides the highest level of medical care available. The model gives Signature Healthcare’s primary care physicians time to build relationships with patients to learn about their unique lifestyles. Our doctors see fewer than 10% of the patients in a traditional practice. This allows them to devote more time to each patient in order to support their health and overall wellness. It also allows our physicians to focus on prevention for optimal health.
Concierge medical practices provide a higher level of care than traditional primary care practices. Signature’s model is based on an annual membership. Our members experience what’s most important to them, such as 24/7 access to a physician, same or next day appointments, and minimal wait times at office visits.
