Jeff Gibson has worked in healthcare (I.T. system architect) for the past 15 years and unknowingly lived with circadian rhythm disruption. After Jeff started improving his light environment a few years ago, he started feeling like a completely new person: physically, mentally, and spiritually. Since then, he's been studying circadian and quantum biology and has been on a mission to convince as many humans as possible to implement these simple strategies in their lives so that they can also experience greater health, happiness, and purpose in the same way he and millions of others on the planet have figured out.

In 2024, Jeff partnered up with his friends from the United Kingdom to create The CRD Challenge: a free circadian education community for anyone who wants to learn the basics of circadian and quantum biology. This three-week-long, bite-sized educational program empowers people to learn the most important aspects of circadian health and easy practices to implement in their life, which will improve their longevity, healthspan and lifespan.

Dr. Thomas Cabell is an invasive cardiologist.

Since high school, Thomas has always been interested in optimising health and performance. Through college and medical school, he knew there was a better way than the current paradigm. For years, it was about the right nutrition and the right exercise.

Since 2022, he has come to understand that visible and non-visible light rules it all, and the science of quantum and circadian biology has blown his mind.

Personally, light, circadian rhythm, and cold therapy have helped him heal his own autoimmune response without medication.

The power this information has to leverage nature to optimise our biology for optimal health, performance, and longevity is astounding.

While working as an invasive cardiologist in a mainstream healthcare setting, he is now on a crusade to educate his patients and other healthcare professionals on this incredible science and its powerful principles.

Erica J Mitchell is a Portland-based photographer who sees light differently.

Her journey started at age three, tagging along with her father, a studio portrait photographer, along the scenic shores of Monterey Bay. That early exposure sparked a lifelong passion for capturing people in their best light - literally.

With a BFA in Photography and Design from The Art Institute of Portland, Erica specialises in natural light headshots and brand photography that helps professionals stand out while also supporting their well-being.

She’s not your typical photographer - Erica is deeply curious about the physics of light and the unseen effects of modern tools.

She’s discovered that holding a camera up to the eye and snapping the shutter can generate over 30 milligauss of EMFS directly to the pineal gland - a hidden hazard few in the industry talk about. Her natural light approach isn’t just an artistic choice — it’s a health-conscious one.

While this is her first podcast, she’s no stranger to public connection - she once hosted a local folk radio show. Clients love her laid-back energy, intuitive eye, and ability to make even the most camera-shy feel confident and seen.

When she’s not behind the lens, Erica’s likely surfing the Oregon coast or gardening her wild, untamed backyard.
