Principal: Mr. Douglas Hosking
Mr. Hosking is moving into his second year as Principal of Most Holy Trinity School in 2021-2022. Before becoming MHT School's VP in August 2019, he founded Cristo Rey San José Jesuit High School, working as the English and Arts Department Chairs. He has worked extensively in Catholic middle and high schools that serve underserved youth, and is committed to building equitable educational systems in the Bay Area.

"Our school stands in our families' corners until our arms fall off.  This 'no matter what'-ness is what separates us from other communities, and it's something I see around MHT every day.  I believe in the power of Catholic schools to be liberatory, moving San Jose toward justice.  Most Holy Trinity's mission to serve Eastside San José is one grounded in the Gospel's call to teach as Jesus did.  I know we can answer it."

Vice Principal: Ms. Darlene Sanchez
My name is Darlene Sanchez, and I am honored to serve in the role as Vice Principal at MHT for the next academic school year. For the past eight years I’ve had the incredible experience of teaching in the Diocese of San Jose at St. Patrick School. During that time, I served students in the classroom and in various youth groups, collaborated with faculty regarding best teaching practices, and partnered with parents and families on various school enhancement projects. Prior to beginning my journey with Catholic schools, I worked for the Alum Rock School District, where I gained perspective and experience with educational policy on various levels. I received my Master of Arts in Teaching and Multiple Subject Teaching Credential from Santa Clara University, and my Bachelor of Arts from San Jose State University. As a parishioner of MHT, and community member of East San Jose, I am fully committed to and highly value educational attainment and college readiness. I have personally witnessed how transformative equitable education can be for our students, families, and region. I am eager to serve the students of MHT and look forward to collaborating with you in the next academic year as we adjust to new norms and walk together with hope and faith, guided by love from our Lord.

On my journey to MHT, I have come to believe the ELA skills are practiced daily, and the single most important thing I can do for my students is build reading as a personal habit.   After spending a year at MHT, I look forward to may more. Our students and community have created a school in which kids are excited to show up every day.  I feel the same way.
