Find Your Personalized Path to Wellness
Your care should be as unique as you are. At CAIRN Medical, it is.
We’re not just another primary care practice—we’re a movement toward healthcare that sees you, listens to you, and is designed around your real needs.
Led by Dr. Louder, our dedicated team of physicians and staff offer a holistic, personalized approach that blends functional medicine, osteopathic principles, and the science of genomics. As a membership-based practice, we take the time to build real relationships and get to the root of what’s going on—so you can stop guessing and start healing.
No more rushed 10-minute visits. No more jumping through insurance hoops.
Our visits are 30 to 60 minutes long—either virtually or in person at our Holland, Michigan office—so we can go deep, not fast.
Genomics Integration: We Gave Up Guessing
Ever wonder if keto’s right for you? Or how your body handles stress, detoxification, or estrogen? With our advanced genomic analysis, we decode your DNA to build your personalized blueprint for health. From nutrition and movement to hormone metabolism and mental clarity—we uncover what your body actually needs to thrive.
This is care grounded in science, led with heart, and built around you.
Join CAIRN Medical and experience the care you’ve always deserved—proactive, personalized, and powerfully informed.
Healing Isn’t Instant—But It Is Possible
Your symptoms didn’t develop overnight. They’ve likely been shaped by years of chronic stress, hormonal shifts, nutritional deficiencies, environmental exposures, unresolved trauma, and other hidden disruptors. These influences can quietly accumulate—until your body finally says, “Enough.”
Real healing takes time. It isn’t about quick fixes or one-size-fits-all solutions. It’s about commitment, clarity, and consistent, skilled support. That’s the purpose of this Membership Program—to provide a clear, structured path toward long-term health transformation, at a pace that honors your body’s unique rhythm and resilience.

Meet Dr. Louder | Founder, CAIRN Medical
What is Your Philosophy of Care?
As a seasoned Osteopathic physician with over three decades of experience, my approach to care is rooted in deep compassion, holistic healing, and the belief that every patient deserves to be truly seen, heard, and understood.
After graduating from Michigan State University, I trained extensively in both Family Medicine and Integrative Holistic Medicine, which laid the foundation for my evolution into Functional Medicine. Today, my practice is grounded in the understanding that health isn’t just the absence of disease—it’s the full expression of your vitality, physically, mentally, and emotionally.
I specialize in personalized, trauma-informed care that acknowledges the profound connection between life experiences and chronic illness. Through our unique Self-Compassion and Connection™ protocol, I help patients navigate complex PTSD and other deep-rooted conditions in a safe, empowering space. Healing isn’t just about treating symptoms—it’s about restoring wholeness.
At CAIRN Medical, we also go beyond traditional care by integrating genomics into your health journey. With our Hero’s Genome™ program, we decode your genetic blueprint to create customized, precise treatment plans that align with your body’s unique needs. This is where science meets soul—allowing you to become the true hero of your health and wellness.
What Differentiates You from Other Physicians?
What truly sets me apart is the blend of experience, deep listening, and the way I partner with each patient on their journey—not just to manage symptoms, but to restore vitality.
With over 30 years in Family Medicine and Functional Medicine, I’ve developed an approach that combines diagnostic precision with a whole-person lens. I stay at the forefront of emerging science, including genomics and trauma-informed care, so that my patients have access to the most advanced, evidence-based tools available—without losing the human connection that matters most.
I take time to get to know each patient’s story, not just their symptoms. Together, we look at their genetic blueprint, lifestyle, history, and goals to co-create a plan that aligns with their life—not just their lab results.
What patients often tell me stands out is the way they feel seen and understood here. I’m deeply committed to clear, compassionate communication and collaborative decision-making. Whether it’s unpacking a complex diagnosis or mapping a healing plan, I ensure you feel confident and supported every step of the way.
I also never stop learning. Through ongoing training, research, and innovation, I bring the latest insights in functional medicine, osteopathy, and genomics into every visit—so your care evolves with you.
At the heart of it, I don’t just treat illness—I walk with you toward wellness, as a guide, partner, and advocate for your health.
Dr. Louder, why did you switch from a fee-for-service model to a membership model of care?
There were many reasons, but ultimately it came down to one truth: I wanted to give my patients the kind of care they truly deserve—care that’s proactive, personalized, and deeply human.
In a fee-for-service model, everything is rushed and reactive. You're limited by time, by billing codes, by what insurance allows—not by what the patient actually needs. That just didn’t align with how I practice medicine anymore.
By transitioning to a membership model, I’ve been able to shift the focus back to what matters most: you.
This model gives me the time and space to build real relationships with my patients. We can actually sit down for 30 to 60 minutes and dive deep—into your history, your lifestyle, your genetics, your goals. That’s where functional and osteopathic medicine thrive: in the details, in the connection, in the whole picture.
It also supports preventive care and empowers patients to engage consistently, not just when something’s wrong. You don’t have to worry about what’s covered or how long you’ll wait—you’re part of the practice. You have access, continuity, and a team that knows you.
Financially, it creates predictability and stability for both of us. There’s less paperwork, fewer middlemen, and more energy spent on what we’re actually here to do—heal.
At the end of the day, a membership model allows me to practice in a way that honors my values, respects your time, and supports long-term, whole-person wellness. And that’s exactly the kind of care I believe every patient should have access to.
