In 2008, Ellen fell into the cell phone/brain tumor world when her husband was diagnosed with a brain tumor attributed to his cell phone use. After studying this extensively and going public with this information on Dr. Oz, The View, Larry King Live and other shows Marks has heard from hundreds suffering or now deceased because they did not know cell phone emissions are tested away from the body. Marks is determined to change that. Marks and her son founded The California Brain Tumor Association in 2009- the non-profit focuses on prevention of primary brain tumors. Marks co-produced the award winning documentary “Mobilize” and is a central figure in the award winning film “Generation Zapped”. Marks was the driving force behind the city of Berkeley’s landmark law placing cell phone safety information at the point of sale. She hopes to take this nationwide. Marks also helped get the California Department of Health to release a cell phone and health document to the public in 2017. In 2017 Marks chaired a group of professionals fighting California’s SB 649- a law which would have usurped all local input and authority in the placement of cellular facilities. They were successful in getting the Governor to veto this bill. She is now working on the 5G issue which is challenging communities across America. Marks gives speaking presentations nationwide on how to live healthy in the wireless era.
