Clausewitz Reyes - Business Attorneys

10/17/2026

What a fun night this past week at San Antonio Youth Literacy's Sip N Spell! 🐝📚 Our Clausewitz Reyes team rallied, sipped, and spelled our hearts out for a cause that is close to home. Our own Shellie Reyes serves on SAYL's Board of Directors, and we were proud to support her and this amazing organization.

Since 1984, SAYL has helped San Antonio kids build reading skills and confidence. Its Reading Buddy volunteers work one-on-one with second graders across more than 65 local elementary schools, with one goal: every child entering third grade reading on level.

Thank you to SAYL and everyone who came out to support literacy in our city! Want to get involved? Visit sayl.org to learn about becoming a Reading Buddy.

We think our attorneys were naturals in front of the camera; don't let anyone tell you attorneys can't have a good time! Thanks to 📸 for the real pics and for making the process so much fun for everyone.
