Director of Facilities Maintenance and Operations, East Side Union High School District, San Jose, CA Roger Silveira has been in the construction and building maintenance industry for more than 30 years. Starting his trade career as an automotive technician, Silveira moved to the more lucrative construction industry. He ran his own construction company from 2003 until 2010. From 2010 to 2014, Silveira worked for a couple of tech companies, but because the focus was solely on shareholder profit, he found the job unsatisfying. It was then that he decided to put his skills and expertise to use in academia, serving students, teachers and school districts. In 2017, he read an article about high CO2 levels in classrooms. From that moment, Silveira became obsessed with learning everything he could about ventilation and excessive CO2 levels in classrooms, ultimately leading him to found We Need Fresh Air. Silveira has certifications from Stanford University, the International Facility Management Association and several trade schools.
