Meet our Faculty & Staff

Justin-Siena is home to an extraordinary group of committed faculty and staff who care deeply about our students. Our teachers encourage and set high expectations not only for Justin-Siena students but also for each other. We recognize that mastery of our craft is a career-long process, one that Justin-Siena generously supports through professional development opportunities, a mentoring program for new faculty, tuition assistance for higher degrees, and other programs that support ongoing learning for our faculty. Learn why our faculty love their craft and their students below.
