We recently reached our 15th anniversary in San Antonio and now we want you to join us in celebrating this milestone! 

We've partnered with Green Spaces Alliance of South Texas to host an Open House at our office!

You'll have an opportunity to meet and talk with staff from SWCA and Green Spaces Alliance. While you're here, learn more about our respective roles in San Antonio; enjoy local brews, wines, and delicious food; participate in a silent auction to benefit Green Spaces Alliance; and explore our office, conveniently located on the Leon Creek Hike & Bike Trail.

Open House attendees will receive a raffle ticket for a chance to win a Yeti Cooler from SWCA and the first 150 people through the door will also receive a special gift!

Thursday, May 11 | 4-7 p.m.
