My name is Roslyn Potter.  I am a master’s prepared educator and registered nurse, a health and safety advocate with a passion for protecting the public through information, education, and research.

In early 2008,  a health crisis from a  serious but odd autoimmune condition led to three hospitalizations and I found myself immersed in research to discover why my excellent state of health had deteriorated so suddenly. Then in 2013, classic electromagnetic hypersensitivity (EHS) symptoms began.   I soon learned that this cluster of new symptoms and the previously diagnosed autoimmune disease were both the result of overexposure to a variety of electromagnetic sources, including the many MRIs taken. I had a new diagnosis, electromagnetic hypersensitivity, or EHS.

Since the early 1980’s, I had spent many hours each day in front of computers for both college and work.  Before the autoimmune diagnosis in early 2008, I had been engrossed in work as a public health lecturer and curriculum developer in disaster preparedness and in the prevention of infectious disease pandemics, at a major university. I also created an educational board game to teach the public how to respond to large scale disasters.

Decades of work in hospitals as a compliance manager with additional consulting work in hospital quality management exposed me to many EMF sources; computers, electronic medical equipment, pagers, cellphones, and other wireless devices.

I’ll never know what exposures pushed me into hypersensitivity but  EHS and the autoimmune disease resulting from overexposure to EMFs were incapacitating at times.  I experienced weakness, trembling, muscle spasms, headaches, respiratory difficulties, rashes, difficulty sleeping, stinging  and burning sensations to my skin, palpitations, difficulty concentrating, memory problems, marked fatigue, and low blood pressure, among other symptoms.

I learned that many thousands of people around the world are experiencing these same problems. We are in the midst of a silent epidemic that is causing serious illness and sometimes, significant disability.

Now, with eight years of personal experience, research and study behind me, I am relatively symptom free due to a combination of shielding, EMF and other pollution management practices in my home and office, and care with nutrition.

My Background

I am a former lecturer and curriculum developer at U.C. Berkeley’s Center for Infectious Diseases and Emergency Readiness, research associate at the Rand Corporation, CDC Infection Control Expert Group member, critical care nurse, hospital epidemiologist and manager of infection control, nursing education and employee health and compliance for hospitals and medical centers, and national speaker on quality improvement and patient safety in healthcare.

More recently I have worked as a online researcher and healthcare consultant / advocate for family members and others diagnosed with cancer and other serious diseases.

My nursing education and training is from Napa Valley College and Sonoma State University. I earned a B.A. with honors  in Mass Communications from U.C.

I have been a registered nurse for over forty years.

I love to travel, enjoy art and nature, garden, landscape, perform simple home repairs, read, and learn.
