This approach is especially helpful for patients who feel unheard, overlooked, or stuck after seeing multiple specialists without clear answers.
Functional medicine takes time, time to listen, connect the dots, and build a comprehensive picture of your health so that your care plan brings clarity, direction, and lasting change.
I’m Sean Campbell, PA-C, a board-certified Physician Assistant with more than 13 years of experience practicing medicine across multiple care settings, including primary care, addiction medicine, and urgent care. Throughout my career, I have seen firsthand the strengths of traditional medicine, especially in acute and emergency situations. I have also witnessed its limitations when it comes to chronic and complex conditions.
Over the years, I have become deeply passionate about helping patients find real answers, especially those who have been struggling with unresolved symptoms or chronic illness. Functional medicine allows me to do exactly that. By combining advanced testing, evidence-based research, and truly listening to your story, I work to uncover the root causes of your health concerns and guide you toward lasting healing.
As a Christian, I believe healing is deeply personal and holistic. I approach each patient with care, humility, and respect, offering clinical insight and compassionate support. When desired, I am open to providing encouragement and guidance that supports the whole person, always honoring each patient’s comfort level and beliefs.
Outside of the clinic, I am a husband and father of three, with two dogs and a cat. I enjoy spending time outdoors, playing chess and pickleball, reading a good book, playing guitar, and starting each day with a cup of cold brew coffee.

I founded Hold Fast Functional Medicine because too many patients feel unheard or dismissed in traditional care. My goal is to understand your unique biology, environment, nutrition, stressors, and life experiences so we can create a personalized plan that restores clarity, builds resilience, and supports your body’s God-designed ability to heal.
As a functional medicine consultant, I work in partnership with your existing healthcare team. I do not replace your primary care provider; instead, I complement their role by offering deeper investigation and a whole-person perspective on chronic conditions and wellness. All patients are required to maintain a primary care provider for routine screenings, acute concerns, and emergencies.
I do not accept insurance, which allows me to spend the time necessary to provide comprehensive, personalized care without the limitations of a rushed, symptom-focused model.
My approach is collaborative and individualized. Healing is not one-size-fits-all and often requires:
To guide this process, I utilize:
This approach allows me to identify the underlying drivers of illness and develop solutions that create measurable, lasting improvement.

Your health journey is more than a series of appointments. It is a collaborative process built on listening, learning, and creating a clear path forward that supports meaningful, lasting change.

A brief discovery call to see if our approach is right for you. No pressure.
"Let us hold fast the confession of our hope without wavering, for He who promised is faithful." - Hebrews 10:23
