Founder and Functional medicine praciticioner
Thomas Duncan, MD
I founded Duncan Integrative Medicine because I believe healthcare should be personal, proactive, and built around relationships—not rushed appointments.
My passion is helping people reclaim something far more valuable than better lab results.
Freedom.
Freedom to wake up with energy.
Freedom to travel, play with your grandchildren, pursue your passions, and live life on your terms.
I combine the best of traditional medicine, functional medicine, and evidence-based lifestyle strategies to create a personalized plan that is practical, sustainable, and focused on lasting results.
My role isn’t simply to treat disease.
It’s to help you build the health that creates the freedom to live the life you were meant to live.
Your health is your greatest investment.
I’d be honored to help you take the next step.
FUNCTIONAL MEDICINE & WOMEN’S HEALTH
Nurse Practioner
Now Accepting applications for new patients
Amanda comes with more than 20 years of nursing experience, including 12 years in emergency medicine. Growing up in Tenino, she is a longtime Northwest native with a deep-rooted connection to the community she serves. It was her own life-changing autoimmune diagnosis that inspired the journey to seek a better understanding of health and longevity.
Amanda’s personal experience with polymyositis, a rare autoimmune disease, changed the way she views medicine. Navigating a complex condition firsthand taught her what it feels like to long for real answers and the need for a provider who searches deeper, looking beyond just symptoms. That experience sparked her passion for functional and root-cause medicine, and it continues to shape the compassionate, holistic care she provides today.
Amanda believes healthcare is more than treating illness. It is helping people build healthier, stronger lives through education, personalized care, and a proactive approach to wellness. Her practice centers on a holistic view focusing on metabolic health, hormone management, and disease prevention. Amanda’s mission is simple: help every patient gain more healthy years, more energy, and more freedom to live life on their own terms.
Practice Manager
Melodie is often described as a “unicorn” with a Swiss Army knife due to the many roles she takes on within the clinic, including clinic administrator, patient coordinator, and clinic ambassador. She possesses a unique blend of business acumen and healthcare expertise, along with strong organizational skills that enable her to create a robust infrastructure for the team. In her free time, Melodie and her husband enjoy hiking in the stunning Pacific Northwest and tending to their hobby farm, but their greatest joy comes from spending time with their grown children and two granddaughters.
Anna became a valued member of our team in April 2021. Known for her bright, cheerful smile and positive attitude, she brings an uplifting energy to both our patients and the workplace. Anna takes pride in helping patients feel comfortable, understood, and confident throughout their experience with our team. Outside of work, she enjoys exploring the great outdoors, spending time with her family, and taking her son to the park to play in the sunshine.
Jennifer joined our team in October 2024 and is dedicated to helping patients feel welcomed, supported, and well cared for. She treasures time with her family, especially her granddaughter and beloved granddogs.
