About
My name is Shane Reilly
I built Optimal Dwelling Spaces LLC to help families lower electromagnetic field exposures at home.
After becoming electrosensitive in 2014 while working as a firefighter, I was propelled on a journey to better understand the hidden sources of EMFs in modern life.
I studied at the Building Biology Institute and now hold an advanced certification as Electromagnetic Radiation Specialist (EMRS).
Since 2017, I've worked with hundreds of clients and referring doctors in Portland, Seattle, and beyond.
Is this service right for me?
