    Grad Stories

    Like so many grads before you, your commitment to higher education and hard work will lead to new career opportunities. Read stories from recent grads below.

    triOS opened so many new opportunities for me. Eight short months later, I completed my NACC exam and was able to begin working with a community care agency.

    It wasn’t easy, but it was worth it. There were tough days, tension in the classroom, moments I wanted to quit, but I stayed the course. I learned to speak up, lead, and grow through the struggle

    Balancing my career and education was challenging, but it opened new possibilities for my future and gave me the skills and confidence to move forward in both real estate and paralegal services.
