Integrative Medicine

Russell H. Greenfield, M.D.

Signature collaborates with Dr. Russ Greenfield to extend an integrative approach to optimal health and wellbeing. Dr. Greenfield’s care is available to members and non-members of the practice at an additional fee.

Dr. Greenfield believes his role is to help support the innate gifts of healing present within each of us. He partners with patients to co-create credible, personalized programs towards optimal health that combine healthy diet and lifestyle practices, as well as select complementary therapies, alongside the best of conventional medical care.

Dr. Greenfield was among the first four physicians to train under the direct guidance of Dr. Andrew Weil in the late 1990s and has been practicing Integrative Medicine ever since. He enjoys spending time with his family, being in the great outdoors, and anything having to do with The Lord of the Rings.

Concierge Medicine

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. Our doctors do not rush through appointments and provide highly personalized, comprehensive care. Schedule a consultation with our team to experience the Signature difference.
