Welcome to Advanced Medical Integration

Patient-Centered Functional Medicine and Primary Care

Advanced Medical Integration is a Direct Primary Care Functional Family Medicine practice.

By having freedom from insurance, we are able to employ a more personalized, patient-centered, whole-person approach to healthcare, rather than a conventional, one-size-fits-all, disease-oriented focus.  Whether you are currently healthy and want a partner in maintaining good health or you are suffering with chronic disease and want to achieve your best possible health, we foster a proactive, vested partnership between patient and physician.

Through this vested partnership, we strive to help heal, educate, and empower our patients. By supporting every patient’s personal potential for optimal physical, mental, and emotional health, we seek to promote and restore wellness throughout one's lifetime.
