As Family Nurse Practitioners we specialize in offering affordable, comprehensive medical care across the life span. We integrate traditional medical care with Functional medicine for a more holistic approach to health and wellness. Functional medicine involves a partnership of the patient and practitioner to address underlying causes of disease. It addresses the whole person with regard to their individual genetics, environmental exposures. life style factors, spiritual, emotional and physical makeup. Each of these factors are an influence in chronic disease and our goal is to address each of these in order to bring about health and vitality.

Integrative and Functional Medicine is for people like you who seek optimal health and freedom from illness.  You will acquire the tools necessary to support your health decisions that are lacking in our current healthcare system. You will gain access to a wealth of information, education, resources and tools that support you on your journey toward health. 

Our Commitment is to be a trusted source of education, information, and community partnership for those needing a helping hand in achieving their optimal health goals.

Our Desire is to break down the relationship barriers between you and your healthcare team. We want to provide a place in the community which facilitates true healing. When you step into our practice, we want you to feel that you are truly cared for.

Our Goal is to provide a road map to help you navigate through health problems within an entirely new frame of reference, one that allows you to understand and address the root causes of disease and ill health rather than just treating symptoms.

Our Wish is to have everyone say, “I’m fulfilling my God-given purpose.” We are committed to making functional medicine available to our community as quickly as possible so that no one will have to suffer for lack of knowledge or access.

Founded in 2011 by Carl Smith FNP-C and Quentin Caswell FNP-C with the passion to help bring back the healthcare provider-patient relationship that is grounded in compassion and personalized care. Everyone’s story is unique and we at Advanced Practice Clinic want to lend that helping hand in your journey to vitality. The need for this type of healthcare environment became evidently clear while working in healthcare environment for over twenty years.
