The CSSLOSA Story
Global Alumni Networking
We facilitate powerful connections among thousands of Commandos worldwide through our digital platform, chapter events, and professional interest groups. Our robust network serves as a vital resource, enabling members to reconnect with old friends, forge new collaborations, and share life experiences and professional milestones.
Mentorship & Career Development
We bridge the gap between generations of Commandos. Our initiatives include structured mentorship programs that offer career guidance to current students and create opportunities for professional growth among alumni. This is inspired by impactful sessions like the "Life After ComLag" event, where senior alumni provide real-world advice to SS3 students on navigating their future.
We are fundamentally committed to "giving back." The association identifies, funds, and executes legacy projects that enhance the learning environment and student welfare at CSSL. This commitment is demonstrated through numerous projects undertaken by various class sets, from renovating medical facilities and upgrading auditoriums to rehabilitating structures damaged by storms.
We stand as a pillar of support for our members in both their personal and professional lives. The association provides a network for mutual assistance and develops initiatives that foster entrepreneurial growth and financial empowerment, reflecting a core belief that all members should grow and succeed together.

Voices of Our Community
"The CSSLOSA network has been an invaluable professional asset. Through the Abuja chapter, I connected with a fellow Commando from a different set, which led to a major business partnership. The discipline we learned at CSSL still binds us."

"Living in Toronto, I felt disconnected for years. Joining the platform and participating in the North America chapter's virtual events made me feel right back at home. It's incredible to see the Commando spirit thriving across the globe."

"The Commando Mentorship Program was a game-changer for me. My mentor, a '92 graduate, guided me through my first career steps after university. That 'Life After ComLag' advice is something you can't get anywhere else."

"Our Class of '95 set decided to upgrade the school auditorium. The association's platform made it easy to organize, fundraise, and execute the project. Seeing the impact on the students today is the greatest reward."

"The announcement of the Alumni Empowerment Fund is a testament to our community's ethos of lifting each other up. It's not just about reminiscing; it's about actively investing in each other's success."
