Diana Carrillo - President

Pauline Martinez- Vice President

Susana Nguyen - Secretary

Hello! I’m originally from Houston, Texas, and graduated from the University of Houston with a degree in Management Information Systems and a minor in Marketing. Professionally, I’ve built experience in project management and coordination, and am currently working in Austin, TX as a Project Administrator at Mission Critical Group!

I crossed Fall 2022, Beta Gamma Class at Epsilon Chapter, and Sigmas has truly been my home away from home. During my time as an active, I served as Service Chair (Spring 23), Fundraising Chair (Fall 23) New Member Educator (Spring 2024), and President (2024-25), each role helping me grow as a leader and strengthening the bonds I share with my sisters. Being NME and President has taught me all about the meaning of sisterhood and I’m excited to expand upon that as this year’s National Board Secretary.

I’m so excited to continue giving back and can’t wait to support our chapters while helping our sisterhood thrive!

Kamila Agnas - Treasurer

Hellooo! My name is Kamila Agnas, and I crossed Fall 18 from San Diego State University, Delta Chapter. I graduated May 2022 with a B.S. in Business Administration, Management. I am currently working as an Operations Executive and Executive Assistant at a business financing company.

I was born and raised in San Diego and I decided to stay local when I chose my college. As a commuter, I wanted to get involved on campus as much as I could. My first year at SDSU I played video games competitively for the school, but decided to get involved in other organizations as well. My second year is where I found Sigmas and where Sigmas found me too.

During my time as an active, I held a few positions. I was Academics Chair (Fall 19), New Member Director (Spring 21), and Vice President (Spring 22).

I’m so happy to have had Sigmas during college, and I am still happy to have my connections there to this day. I will always hold this organization close to my heart and am happy to keep building connections forward! I’m happy to serve my second year as National Board Treasurer, and I will always strive to provide any help to keep this organization running and growing!

Kaitlynn Nguyen- Philanthropy Chair

My name is Kaitlynn Nguyen, and I crossed in Fall 2019 at the University of Houston, Epsilon Chapter. I graduated in December 2022 with a Bachelor’s degree in Human Resource Development, and I am honored and excited to serve as the National Board Philanthropy Chair for Sigma Phi Omega.

In my active ship, I held multiple positions, including Service Chair, Rush Chair, Fundraising Chair, President, and New Member Director.

Giving back to the community has always been a passion of mine, and I believe philanthropy is at the heart of what it means to be a sister of Sigma Phi Omega. In this role, I look forward to creating meaningful opportunities for our chapters to connect with causes that inspire them, strengthen our collective impact, and continue building on the legacy of service that defines our sisterhood. I am excited to work alongside the National Board and all of our chapters to grow our philanthropic efforts and empower sisters to make a difference together.

Kayla Madelar - California Governor

ello! My name is Kayla Madelar, and I crossed Spring 21 Alpha Lambda Class at San Diego State University, Delta Chapter! I graduated SDSU in May 2023 and earned my B.S. in Biology. I currently work full-time in a dermatopathology lab here in San Diego.

I was born and raised in sunny San Diego, and honestly, it’s hard to leave America’s Finest City, so I didn’t! I decided to stay here to continue my education. I started out at community college and then transferred to San Diego State University. As a transfer student, I joined Sigmas in my Junior year. At first, I was a little unsure, because I thought maybe I wouldn’t get the full experience since I didn’t join freshman year. But that definitely wasn’t the case. Joining Sigmas was one of the best choices I’ve made. I’ve built amazing friendships and had experiences I’ll never forget! Throughout my time with Sigmas, I was Rush Chair, Academics Chair, Service/Philanthropy Chair, New Member Educator, and Alumni Advisor.

This sisterhood has given me so many great memories and friendships, and I’m looking forward to giving back and making even more along the way. Can’t wait to see what my first year on National Board has in store!

Trish Nguyen - Texas Governor

Haiii! My name is Trish, and I crossed in Spring 2022, Beta Omicron class at Gamma Chapter. I’m originally from Houston, TX, and recently graduated from the University of Texas at Austin with a BSA in Human Development and Family Sciences, along with minors in Health Communication and Professional Sales & Business Development. Currently, I work in Tech Sales at Dell Technologies in Nashville, TN!

Coming into college during COVID, I remember how difficult it was to socialize and build genuine relationships in the age of Zoom calls and virtual classes. My sister, a Houston Sigma, encouraged me to rush during my first semester. While I was interested, I decided to take that first semester to focus on adjusting to college and exploring other organizations.

By the spring semester of my freshman year, I found myself feeling very homesick and longing for meaningful friendships. I decided to attend Sigma’s info session and accidently came early, but immediately felt at home. The bright personalities, sense of humor, and strong bonds of sisterhood among the members left a lasting impression on me. I knew then that I had found something special and I’ve never looked back.

During my time as an active, I served as Junior TAPC Delegate, Recruitment Chair, Scrapbook Historian, and received Best Active during my final semester.

As I grew within the organization, I truly came to understand what older actives meant when they said, “You gain so much more than you expect when joining.” Watching younger members grow into confident, capable women while developing professional skills and lifelong friendships was incredibly rewarding. There truly is no other sisterhood like Sigma Phi Omega.

I’m honored to give back to the organization that has given me so much as Texas Governor and I couldn’t be more excited to serve as a bridge connecting our sister chapters and helping our Sigma sisterhood continue to grow!
