My Story
My Story
In 2018, I discovered that I have a hypersensitivity to electromagnetic fields.
Ever since then, I have been working diligently to learn as much as I can about how to reduce my exposure to human made electric fields, magnetic fields, and radio frequency radiation. Applying this knowledge to my life resulted in a greatly improved electro-climate in my home, making it a refuge where I can recover from daily exposures. This is something I want to help other people do - create a sleep sanctuary in a low EMF home.

My realization that I was EMF sensitive was a cut-and-dry case. I was working as a carpenter for a company that was building new homes in a development. Then I was asked to do some repairs inside a finished home which was occupied, complete with all of the usual high tech gadgets of a modern home. Strangely, after a few days of working there, I found myself feeling extremely lethargic every time I went into the house. I took a lunch break in my car and when I returned, the fatigue returned as well. Pondering my predicament, I suddenly had the thought, "Maybe its the WiFi". I went downstairs, unplugged the WiFi, and within minutes, my energy returned. I could now complete my project. That was when I knew for sure that this technology is not benign.
The reason I was able to even think of unplugging the WiFi was that, thanks to my wife' sensibility, we never had WiFi in our home. We used hardwired Internet and limited our cell phone use by using a corded landline.
But now I was devastated as I began to realize that I was reacting to many mysterious sources of EMFs. I couldn't go into stores without getting brain fog and feeling like I had an "electric flu" which would last long after leaving the building. I couldn't visit friends and family in their homes. My sensitivity was growing.
I then began fervently studying EMF mitigation by researching online, consulting with experts, and taking a class on EMF instrumentation. Next I cleaned up the EMF issues present in my home as much as I could. This was my first home purchase and it turned out I had high AC magnetic fields caused by a wiring error which affected my bedroom. It became a process of figuring it out as I go; an invaluable hands on learning experience that has led me to where I am now, able to quickly interpret the information I gather in my EMF inspections.
​Once I felt like I knew what I was doing, I offered my new found skills to friends and people in my community. Each situation brought a deeper understanding of the complexities involved - and of course, more questions about how to do things in the best way. It was clear I needed more training, but I was sure it had to be the best training.

​A friend and local smart meter activist who had done some basic measurements in my house suggested I become a Building Biologist. I had never heard of it before, but when I looked at their website I knew instantly that this was the perfect path for me; an institute that teaches people how to make homes truly healthy, using Nature as the gold standard. So as soon as I was able, I enrolled in certification from the Building Biology Institute (BBI) which filled in the gaps in my knowledge and enabled me to hit the ground running with confidence.
As of February, 2023, I am a BBI certified Electromagnetic Radiation Specialist, Environmental Consultant, and New Build Consultant. Along with the excellent training came the opportunity to join the network of BBI professionals. We support each other in the continual learning process needed in this complex and evolving field of study.​
I look forward to helping you navigate the wild world of EMFs.
