At TreePeople, we’re passionate about environmental justice. The vision of a greener and healthier Los Angeles created and enjoyed by everyone in our city is what spurs us on. So we’re delighted to be media partners with Liberty Hill, L.A.’s social justice foundation, for their September 8 event Change L.A., a party with a purpose.

This will be a lively gathering of more than 200 progressive donor-activists who share a commitment to environmental and social justice. Change L.A. will be celebrating two inspiring Angelenos: Shawn Landres of Jumpstart, an entrepreneur at the intersection of innovation and social good; and Tammy Bang Luu of Labor Community Strategy Center, a dynamic community organizer who also has been co-host of radio show “Voices from the Frontlines.”

The event takes place on Sunday, September 8 from 3:30 to 5:30 pm at Busby’s East on L.A.’s Miracle Mile. Tickets are $100 at www.libertyhill.org/changela.
