In 2016, sex trafficking got too close to home. In her words, "It woke me the hell up to one of the most complex epidemics my city has ever seen!" She started collaborating with 30+ anti-sex trafficking nonprofit leaders in the Houston area to understand the services, gaps and areas that needed strengthening, thus was formed, the Houston Area Against Trafficking Initiative (HAAT) which meets at her house every month.   


She is now trying to wake a sleeping giant, her community, and is a community leader and advocate for victims and survivors determined to create massive awareness regarding prevention, intervention, and recovery via community uprising and corporate involvement. To do so, a group of the top 20% of influential Houston leaders is coming together to get behind this movement, they are The Houston 20!  


In order to engage the corporate community, Jennifer and other business colleagues co-founded the Oil and Gas Trafficking Awareness (OGTAG) group, which includes 20 operators and 25 service companies, to collaborate on ideas and initiatives to mobilize the energy industry to join the fight against sex trafficking. Recently, OGTAG conducted an industry-wide awareness event in 5 areas of the City of Houston.
