Meet the Fortress Family

 

We’re Valeria and Felipe, the family behind Fortress Strength Gym. Fortress was created through our faith, hard work, and love for our family and community.


While raising our children, working full days, and building this gym, we’ve experienced plenty of early mornings and late nights. Fortress reflects our real life and our belief in discipline, perseverance, and growth.


We created more than a place to exercise. We wanted a space where people feel welcomed, supported, and seen—a place where you can come as you are, put in the work, and become stronger in every way.


Thank you for being part of something so personal to our family.
