Mission Statement

Model United Nations San Antonio (MUNSA) is a non-profit, student-run organization that seeks to create a dynamic and hands-on learning opportunity for students from the San Antonio area, the state of Texas, the United States of America, and Mexico. As a simulation of the United Nations, MUNSA strives to offer a forum in which academic, leadership, and interpersonal skills are combined to foster student discussion of our world's most pertinent issues.


A special thanks to Ms. Andrea Puentes and Mr. Luke Freeman for their endless support and dedication as sponsors of the MUNSA program. On behalf of the MUNSA staff, we wish to express our sincerest gratitude to them for taking on this role and carrying the legacy of MUNSA onward.

We also wish to recognize Dr. Angela Breidenstein, an associate professor at Trinity University, who works tirelessly to ensure we have the resources required to make our conference a success.
