Geicil - Welding Graduate
After moving to the U.S. from the Philippines and starting a family, Geicil knew it was time to pursue a career that could provide the future they all deserved. When her husband told her about Tulsa Welding School, she took the leap. She graduated in just seven months and landed a welding job shortly after graduation. Today, she’s a high-frequency TIG welder doing work for the U.S. Navy, a mission close to her heart with her stepson serving. She’s proud of how far she’s come and hopes her story inspires others to work hard and aim high. Hear her story on how TWS changed her life.
Michael - HVAC/R Graduate
Growing up in 1980s–90s Los Angeles, Michael faced the daily pressures of gangs and drugs. After asking himself, “Would my father be proud of the man I am today?” he realized it was time for change. While working in a warehouse, a chance moment with an HVAC technician sparked a new path, and he enrolled at Tulsa Welding School. After graduating and working as an HVAC/R tech, Michael earned his contractor’s license and eventually launched his own business. Today, Michael enjoys traveling with his son to BMX competitions and living life on his own terms. He calls TWS the launchpad for the incredible journey he’s on now.
