Dr. David Marquis, DC DACBN

Dr. David Marquis, DC DACBN Dr. Marquis is a Functional Medicine doctor who goes beyond symptom management medicine.

How many people do you know that think they have some form of "ADD or Aspergers", or just get "Foggy in the Brain" and are forgetful of names and places or those who stumble or trip a lot. These are all subtle signs of a Brain Imbalance that affect health in ways that will totally surprise you. Patients who have unrecognized neurological symptoms due to an imbalance between their left and right br

ain hemispheres need help and medication isn't always the solution. Drugs treat the hemispheres equally, where as Brain Based Therapy can treat a specific area in the brain; effectively helping the patient recover from symptoms and conditions caused when the brain is imbalanced. These unique therapies when combined with proper fuel delivery (metabolism) allow patients to succeed in overcoming their blocks to optimal health. After a complete evaluation which often includes full labs and physical exam along with history to determine the actual cause of complaints Dr. Marquis will implement an equally comprehensive treatment plan. He will leave no stone unturned to assist his patients in their recovery.

Pathways to health bone building protocol! Strong bones aren’t built by one thing—they’re built by a system 🦴✨

If you’re serious about bone health, here’s the foundation we use:

• Remove inflammatory triggers (gluten, dairy, soy)
• Optimize stomach acid for better mineral absorption
• Prioritize Vitamin D + K for proper calcium utilization
• Add a high-quality bone mineral complex daily
• Train smart: resistance + impact = stronger bones
• Support the gut with targeted probiotics

This isn’t a quick fix—it’s a protocol.
Because real bone density comes from consistency, not shortcuts.

Your bones are living tissue. Train them, fuel them, support them. 💪🏼🦴

What is the difference between Osteopenia and Osteoporosis? Make sure you know the density of your bones with a DEXA scan! Check out this video for more info 🦴🦴🦴🩻

Strong bones aren’t built by chance—they’re built with the right stimulus 🦴✨

The TurboSonic machine uses high-frequency vibration to stimulate bone growth, improve density, and support overall skeletal strength at the cellular level. Think of it as a gentle but powerful way to “wake up” your bones—helping them remodel, rebuild, and stay resilient over time.

Perfect for anyone focused on longevity, injury prevention, or optimizing performance from the inside out.

Your bones are living tissue—start treating them like it.

Meet Dr. Dave Marquis🌊

Surfer, skier (now… for safety reasons), pickleball guy, backpacker, husband, dad of 4 —and the one keeping this community moving.

California raised, he made his way through BYU–Hawaii for biology, earned his doctorate in Portland, and then did what anyone who loves the ocean would do… moved back to the Central Coast. He’s been serving this area for nearly 30 years!

He’s not just treating injuries—he’s lived them. 🩻Including a broken a spine, clavicle, neck… he’s been through it, fixed it, and now helps others do the same.

Fun fact: speaks fluent Japanese and used to give tours in Hawaii… fully in Japanese, jokes included.🌺🏝️

If you see him in the water, he’s probably surfing.🏄‍♂️

If you see him on land, he’s probably playing guitar or talking about how to keep your body working like it should 🎸

Keeping you moving—so you don’t have to slow down 🤝

March is Brain Injury Awareness Month 🧠💚🍀

Concussions aren’t just a one-time event—and it’s not only major hits that matter. Repetitive microtraumas (think small, repeated impacts, stress, or inflammation) can quietly add up over time, leading to something called *microglial priming*.

Microglia are the brain’s immune cells. When they’re “primed,” they become more reactive—meaning future stressors can trigger exaggerated inflammation, brain fog, mood changes, and slower recovery.

The good news? Your brain is incredibly adaptable when given the right support.

To help your brain heal and stay resilient:
✨ Prioritize quality sleep (this is when your brain detoxes)
✨ Support blood flow + oxygen delivery (movement, breathwork, cardiovascular exercise)
✨ Regulate your nervous system (vagus nerve work, cold exposure, mindfulness)
✨ Reduce inflammation (nutrition, hydration, limiting toxins)
✨ Stimulate and retrain the brain (vision work, balance, neuro-based therapies)

Healing the brain isn’t just about rest—it’s about the right inputs.

If you’ve had a concussion (recent or years ago) or deal with lingering symptoms, it’s not “just in your head.” There are real, physiological reasons—and real ways to improve.

Your brain can change. Your brain can heal. 🧠✨

Not all healing comes from one direction—sometimes the magic is in the combination ✨

We’re layering powerful therapies to support this patient from the inside out:
pEMF chair + NormaTech compression to boost circulation and lymphatic drainage,
ReBuilder on the feet to activate and wake up nerve pathways, and cold laser over the vagus nerve to shift the body into a calm, parasympathetic state—where true healing happens.

Pulsed electromagnetic frequency.
Near infrared light.
Compression therapy.
Targeted e-stimulation.

Individually, each modality is effective—but together, they amplify results. Think better digestion, improved nerve signaling, enhanced recovery, and a body that can finally relax and restore.

Because real healing isn’t one-dimensional… it’s integrated.
