Recent Changes

Dear Sponsors,

On behalf of the Secretariat and the entire MUNSA staff, I would like to welcome you to participate in MUNSA XXV: Horizons, which will take place in January 2021. This year, the COVID-19 pandemic has challenged us to find new ways of engaging our wonderful MUNSA community while creating a conference experience that is safe and enjoyable for everyone involved. More information about conference fees, schedules, and registration will be released as the situation develops.

Horizons is about looking to the future as a global community and using collaboration, respectful diplomacy, and innovative ideas to overcome the challenges that face our world. It is about harnessing the full power of ingenuity and adaptation to create a sustainable and safe future. It is with this spirit of innovation and responsibility that we are announcing for the first time ever, MUNSA will be an online conference. Our Secretariat and staff are hard at work to ensure that we continue to offer delegates the best experience possible while ensuring the safety of everyone involved, and we are excited to see the new possibilities that this change can open for our conference.

I am also pleased to announce that MUNSA XXV: Horizons has partnered with the International Youth Foundation (IYF) this year, and a portion of the proceeds from fundraisers and conference fees will benefit their work around the world to empower young people. IYF is committed to the idea that “educated, employed, and engaged young people possess the power to solve the world’s toughest problems.” This is a truly remarkable organization, and I encourage you and your delegation to engage with them on their website, which I have linked here. We are particularly excited about their Global Youth Resiliency Fund, which will help young people mobilize in response to the COVID-19 pandemic by supporting youth-led ventures. Engaging with the IYF is a wonderful way to remain involved with our organization for the time being.

We hope that you will continue to engage with our conference through social media. You can follow our Instagram at @munsanantonio , Facebook at MUN San Antonio, and our Twitter, @munsanantonio for more information on our organization!

If you are a sponsor of a school that has not attended MUNSA before or if you have attended MUNSA before but want to be contacted at a different email than you have previously registered with, please fill out this form to be added to our mailing list. 

I look forward to working with each and every one of you. Should you have any questions or concerns, you can contact me at mmackey4212@stu.neisd.net or munsaisa@gmail.com

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.
