A Life Transformed, A Mission Born
The most powerful transformations often emerge from our greatest challenges. For me, that moment came in 1997.
After practicing as a Doctor of Chiropractic Medicine for over 14 years and conducting more than 100,000 patient visits, a severe auto accident stopped me in my tracks. What could have been the end became a profound beginning. That experience catalyzed a complete transformation in how I understood health, healing, and what it truly means to thrive as a human being in this complex and confusing world.
Looking back at my journey, I started where many health seekers do: as a teenage natural bodybuilder, winning local and state competitions, fascinated by what the human body could achieve. Learning everything I could about health and how I can be optimal in every way imaginable. But I quickly became more interested in the deeper questions once I started to see that most everyone is sick to some degree.
How do we truly detoxify and or keep cleansed both externally and internally? What role do parasites play in a variety of acute and chronic illnesses? How can we regenerate and optimize / advance areas of the mind and body rather than just maintain? These weren't just academic questions for me; they became my life's research.
The Birth of Terrain Modification
Over four decades of research, experimentation, and clinical observation, I've developed what I call Terrain Modification: a comprehensive approach to upgrading, enhancing, and optimizing every aspect of our health, wellness and advancing consciousness.
Here's what I've discovered: most of us are asking the wrong question. We ask, "What can I add to get healthier?" when we should be asking, "What do I need to remove or omit?"
In my view, true health doesn't really come with accumulation. It comes mostly from elimination. The secrets to a life full of health, wealth, happiness, purpose, and evolution don't lie in how much we need or take. They lie in how little we actually need to take or utilize.
This philosophy forms the foundation of everything I teach at Earther Academy. It's about becoming minimalist - as far as minimizing toxicity in all its forms and realism in our approach to wellness, understanding that our greatest health challenges stem from toxic accumulation, both physical, emotional, ethereal and psychological or mental.
What Is Terrain Modification?
When people first hear about Terrain Modification, they often think it's just another detox protocol. It's so much more than that.
Terrain Modification is about transforming your internal and external environment on every level: from the microscopic bacteria in your gut to the thoughts patterns in your mind, from the air you breathe to the way you move your body or don't, from cleaning and detoxing the skin and pores protocols. I've identified over 80 departments of terrain that we can modify, upgrade, and optimize.
The central themes I teach in terrain modification are: Reset, Renew, Rebuild, Upgrade, Enhance, and Optimize.
Through the protocols, practices, and principles of Terrain Modification, I have guided people from:
- Toxic accumulation to deep cellular cleansing
- Acidic terrain to alkaline balance and remineralization
- Parasitic infestation to microbial harmony
- Mental fog to crystal clarity leading more to igniting critical thinking
- Survival mode to thriving consciousness and a body that can outperform the previous version of yourself
- Removing unwanted body fat through a variety of simple protocols and concepts
Over the past 40 years, in my experience working with thousands of patients and students, I've found that transformation happens when we address health holistically and upgrade our lifestyles to a cleaner and less toxic way. You can't separate the body from the mind, the physical from the ethereal, the emotional from the mental. Everything is interconnected, and when we modify our terrain in a positive way, we shift everything.
So, the bottom line is after 40+ years of research and clinical study:
Terrain Really Matters, once you find this truth that terrain really matters then keeping healthy, wealthy, happy and wise is really very easy and fun!

The Super-Naturalistic Lifestyle
I pose a powerful question to everyone who finds their way to this work: "How do we live the least toxic and least self-destructive life as human beings within a toxic and self-destructive world surrounding us?" and of course when we feel great we all do greater things.
The answer, I believe, lies in what I call the Super-Naturalistic Lifestyle. This isn't about perfection or living in a bubble. It's about making conscious, informed choices that honor life in all its forms - including your own.
This simple approach is grounded in three principles I live by: Easy, Efficient, and Economical.
Easy: Health shouldn't be complicated even though there is much deceit and trickery but on the other hand there is much good information out there too it's just very difficult to find. I've spent decades simplifying complex protocols so most anyone can implement them, regardless of their current knowledge level or dietary preferences.
Efficient: We're all busy. The protocols, practices and principles I teach deliver maximum results with minimum time investment. Once you invest time learning and practicing the protocols, over time you will be removing accumulated toxicity out of your body and this will greatly enhance your health and wellness. This is about working smarter, not harder.
Economical: True health shouldn't bankrupt you - it does take time to learn though. I focus on techniques and approaches that are accessible to everyone, using simple, mostly affordable tools and ingredients. Most people will spend their lifetime accumulating wealth and not put time into themselves, keeping the body and mind running leaner and cleaner. Then in time most of the people / families will fall prey to sickness and your wealth and lifeforce get siphoned right back to the medical systems. Keeping yourself healthy, wealthy, happy and wise is a lifelong learning and experimental adventure. Spending personal time towards learning and practicing a healthier lifestyle is one of the keys to mastering yourself.
Earther Academy: Your Path to Self-Mastery
In 2008, I launched the Earther Academy YouTube Channel to share the protocols and philosophies I'd been developing. The response was overwhelming. Tens of thousands of people around the world began taking more control of their health, sharing their transformations, and asking for more in-depth guidance.
That's when Earther Academy as an online learning platform was born.
Today, Earther Academy serves as a comprehensive Mind and Body Research Institute where I've compiled over 40 years of research into more than 600 detailed video courses. These aren't just lectures; they're hands-on workshops, practical guides covering everything from skin and pore cleansing to advanced detoxification protocols, from sun healing techniques to lymphatic system optimization, from weight loss to fasting, from parasites to beginning / advanced sauna and gwashing protocols and techniques.
I also have produced 160+ Rethinking Reality Videos, covering many out of the box and personal realizations over a variety of subjects as my consciousness evolved and changed over the years.
I've found that the most successful students are those who become their own health advocates. I'm not here to be your guru or tell you exactly what to do. I'm here to share what I've learned and practiced and the results I personally had along with many others over time. The concept and idea is to give you the tools, insight and knowledge, and empower you to become your own teacher and healer of yourself.
The academy includes courses for:
- Beginners just starting their health journey
- Intermediate practitioners deepening their understanding
- Advanced students ready for intensive terrain modification
Every course I create comes from real experience and practice with others. These are protocols I've tested over and over on myself and patients, refined through decades of practice, and have seen these protocols be a positive force and life changing to many 10's of thousands of people worldwide.

The Hawaii Sanctuary
I live and teach from a private 30-acre organic farm and what I call is a natural sanctuary in Hakalau, Hawaii, along the breathtaking Hamakua coast. In Hawaiian, Hamakua means "Breath of God," and I can tell you from living here, it's aptly named.
This location isn't just beautiful; it's essential to the work. The Big Island offers the cleanest air on the planet, abundant fresh spring water, rich volcanic soil for growing just about anything here all year long, and an energy and clean super charged air that's unlike anywhere else on Earth. The property features on-site waterfalls, fresh water pools, extensive organic gardens, ocean views, two infrared saunas, a distilled water steam room, 34 degree cold plunge, stretching and exercise gym, and access to the wild superfoods and probiotic-rich ferments I use daily.
The Sanctuary has a variety of domesticated exotic Macaws, large African Secada tortoises, Turkeys, Ducks, over 40 Sheep, Cattle, several bottle fed 400 pound Russian boars and thousands of wild resident birds and animals that feed off the abundance of food that is produced on the property.
From this sanctuary, I occasionally offer hands-on retreat experiences where small groups can immerse themselves completely in the Terrain Modification lifestyle for 21 days at a time. These retreats have been life-changing for many participants, giving them the focused time and guidance to make profound shifts in their health and consciousness.
Take a look at our Health Retreat Interviews and many Hands on Workshops tab with retreat participants.
A Global Community of Health Seekers
What moves me most about this work is the community that's formed around these principles. I receive messages very regularly from people who've reversed chronic conditions, eliminated decades of pain, lost many pounds of toxicity, regained their vitality along with clarity of the mind, and discovered a new much deeper relationship with their bodies and minds.
This isn't about following me but I will show you how I use these protocols. It's really about reclaiming your power back. It's about understanding that only those who choose to help themselves can truly transform themselves and be a beacon for others to experiment with a healthy and less toxic lifestyle. I provide my personal roadmaps, the protocols, and the knowledge I have gained though direct experience, but you must walk the path yourself.
