Dr. Thomas Duncan - Primary Care Physician

 Functional/Integrative Health



Established patients with our practice may schedule same day appointments


From very humble beginnings, Dr. Duncan emerged as a shining example of determination and resilience. Despite his parents' lack of formal education, they instilled in him the values of hard work, honesty, and integrity. Inspired by his blue-collar background, Dr. Duncan embarked on a journey to pursue higher education, fueled by his family's unwavering support.


To fulfill his dreams of attending college, Dr. Duncan joined the ROTC and dedicated four years of his life to serving as a regular army officer. His dedication and commitment did not go unnoticed, as he was awarded an army scholarship for medical school. Driven by a sense of duty, he then served as a medical doctor in the army for an additional seven years.


Dr. Duncan is a proud father of two grown boys, each with their own unique paths in life. His oldest son has found his passion in the automotive industry, working diligently as a full-time automotive mechanic and finding joy in the art of modifying and restoring old cars. Meanwhile, his youngest son has autism and resides in an adult home. Through his youngest son, Dr. Duncan has learned invaluable lessons about the importance of being present in the moment and cherishing each day as a precious gift.


Witnessing the limitations of traditional reactive medical care, where problems are addressed only after they arise, Dr. Duncan felt compelled to make a change. He envisioned a proactive approach, one that would anticipate and navigate obstacles before they became insurmountable. It was this vision that led him to establish Duncan Family and Integrative Medicine, a practice committed to creating and nurturing health rather than simply reacting to illness.


With Duncan Integrative Medicine, Dr. Duncan sought to revolutionize the way healthcare is delivered. By combining the best of traditional and alternative medical practices, he offers a comprehensive and holistic approach that addresses the underlying causes of health issues. Through his integrative approach, Dr. Duncan aims to empower his patients to take control of their well-being and lead vibrant, fulfilling lives.


Dr. Duncan is not just an ordinary doctor; he is a compassionate and dedicated healthcare professional who truly goes above and beyond for his patients. He can often be found in the lobby, engaging in heartfelt conversations with those awaiting their lab work. Dr. Duncan believes in building genuine connections and treats his patients like an extension of his own medical family. 


One of Dr. Duncan's greatest strengths is his exceptional listening skills. He doesn't just hear the words spoken by his patients; he understands the underlying emotions and subtleties behind their concerns. This deep understanding allows him to approach their healthcare from a holistic perspective, considering not only their physical well-being but also their mental and spiritual aspects. Together with his patients, he collaborates to create personalized and precise health plans that are both effective and practical. 


But Dr. Duncan's support doesn't end there. He remains vigilant in following up with his patients, guiding them through their healthcare journey. He recognizes that achieving good health is a skill that requires not only medical expertise but also a positive psychology and mindset. By sharing his own health journey, Dr. Duncan inspires others to follow in his footsteps.


Dr. Duncan's guiding principle is simple yet profound: to find fulfillment, one must first serve others. This philosophy resonates strongly with his patients, who consistently express their gratitude for feeling truly heard and understood. Dr. Duncan wastes no time in taking immediate action, applying the best practices from various medical modalities to ensure his patients receive the highest quality care. This commitment to integrative medicine sets him apart as a healthcare provider who strives for excellence in every aspect of his practice.


Dr. Duncan's humble beginnings, accessibility, genuine care, attentive listening, and comprehensive approach to healthcare make him a remarkable and trusted physician. He is a true advocate for his patients' well-being and a beacon of inspiration for others on their own health journeys.

Optimize Your Health, Optimize Your Life

Initial Program: Looking to implement FirstLine Therapy is an evidence-based, clinically designed operating system for implementing personalized lifestyle medicine i.e. nutritional and behavior modifications.

The Defining Principles of Integrative Medicine

  1. Patient and practitioner are partners in the healing process.

  2. All factors that influence health, wellness, and disease are taken into consideration, including mind, spirit, and community, as well as the body.

  3. Appropriate use of both conventional and alternative methods facilitates the body's innate healing response.

  4. Effective interventions that are natural and less invasive should be used whenever possible.

  5. Integrative medicine neither rejects conventional medicine nor accepts alternative therapies uncritically.

  6. Good medicine is based in good science. It is inquiry-driven and open to new paradigms.

  7. Alongside the concept of treatment, the broader concepts of health promotion and the prevention of illness are paramount.

  8. Practitioners of integrative medicine should exemplify its principles and commit themselves to self-exploration and self-development.

The Functional Medicine model is an individualized, patient-centered, science-based approach that empowers patients and practitioners to work together to address the underlying causes of disease and promote optimal wellness. It requires a detailed understanding of each patient’s genetic, biochemical, and lifestyle factors and leverages that data to direct personalized treatment plans that lead to improved patient outcomes.
