Kathy Sokolic

Secretary

Kathy has long been a champion of new urbanism and environmental values, and became more directly involved in street safety after her nephew was incapacitated after being hit by a pickup truck in 2016. She joined other local activists to demand changes in street design and policy to prevent these injuries from happening to other families.
She is a co-founder and current chair of Central Texas Families for Safe Streets, an independent membership organization that works with Vision Zero Texas and others to end traffic deaths in the Austin and San Antonio metroplex.
Kathy holds both a BS and MS in Geology from the University of Oklahoma. For a good portion of her career, she cleaned up after the military, disposing of unexploded ordnance. In 2016, she opted for a change and now helps Austinites buy and sell residential real estate.
