Principal: Mr. Douglas Hosking
After serving as Vice Principal for one year, I will be transitioning into my first year as Principal of Most Holy Trinity School in 2020-2021. Before becoming MHT School's VP in August 2019, I founded the English and Fine Arts Departments at Cristo Rey San José Jesuit High School. I have worked extensively in Catholic middle and high schools that serve underserved youth, and I am committed to building equitable educational systems in the Bay Area.
Thank you for welcoming me with such open arms to Most Holy Trinity School. At MHT next year, we will respond to “racial and ethnic tensions, war and exploitation of poor nations by developing in our students a commitment to community” (To Teach as Jesus Did #109). I believe in the power of Catholic schools to be liberatory, moving our city 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: Mr. Francisco Castillo-Fierro
Hi everyone! My name is Francisco, and I’ve had the blessing to be in Catholic education for ten years and counting. I’ve taught elementary, middle, and high school both domestically and abroad, and I received my Masters in Education, along with my Masters in Educational Leadership, from the University of Notre Dame. I am extremely passionate about standing with the underserved; I benefited from helping hands at my schools growing up, and I am very much looking in a mirror when I am with the students at our schools. I know how powerful it was for me to have agents of change in my life who were people of color, and to be a leader of color for a student community is extremely important to me. The Jesuit tenets of cura personalis and being a person for and with others is something that I feel very strongly about, and I do my best to live these out on a daily basis. I’m so excited to be joining the MHT family, and I am confident that we will do incredible things for our students and for our community amidst an unprecedented time in our history.
Kindergarten/Transitional Kindergarten: Ms. Ashley Ronsse
My name is Ashley Ronsse and I am excited to teach kindergarten at Most Holy Trinity school! I love being part of the immense growth that kindergarteners experience from their first day of school to the end of the year. It is amazing how much they learn and develop in this short time. I received my bachelor of arts in Communications and Media Studies from Sonoma State University and a Master of Arts in Teacher Education from the University of San Francisco. I also received a Multiple Subject Teaching Credential from the University of San Francisco. This is my second year teaching kindergarten at MHT and I also have experience in second grade in other schools in the diocese as well as in public school. I enjoy teaching in the diocese because it allows me to share my faith with my students. I am called to teach at MHT because of the mission to educate the whole individual.
1st Grade: Ms. Sarah Peñalosa
Hello! My name is Sarah Peñalosa, and I will be teaching 1st grade at Most Holy Trinity School in the fall. MHT feels like home for me. I grew up near this area and I attended this parish as a kid, attending the fall festivals with my big Filipino family and receiving most of my sacraments from baptism to confirmation here. When I think of MHT, I think of a strong community of diverse strengths and gifts. I am excited to be part of MHT School's mission of empowering lifelong learners and instilling important skills for students to become responsible advocates for themselves and others. I received my B.A. in Humanities for Teaching at Seattle University and my Master's degree in Teaching Urban Education and Social Justice at the University of San Francisco last year. Since then, I have taught 2nd grade in the Evergreen School District and have been a classroom teacher for 1 year now. I am excited for all the academic, social, and emotional growth in first grade, and I am looking forward to meeting you all!
2nd Grade: Ms. Taylor Rogers
I'm so excited to be returning to MHT for my third year of teaching Second Grade. I love 2nd because it is such a fun age where the kids start to become more independent, but still have a fun-loving goofy side to them. I received my BA in Psychology from the University of Redlands and just recently graduated with my MA in Teaching from Santa Clara University. I love that MHT celebrates all cultures and backgrounds. Some of my favorite memories have been from our celebrations of Tết and Flores de Mayo.
3rd Grade: Carla Oliveira
My name is Carla Oliveira and I teach third grade. I love third grade because the students are independent and they eager to learn. I have taught in the Diocese of San Jose for twenty-two years. I have taught second grade for eight years and third grade for fourteen years. I have a BA in Child Development from San Jose State University. I took my credential classes at National University and I have Blended Learning Certificate from Santa Clara University. I have been teaching at Most Holy Trinity School for fourteen years because I love the students and their families. I love the feeling of community and our Catholic identity. Both of my daughters attended MHT. My oldest graduated in 2018 and my youngest will graduate in 2021.
4th Grade: Ms. Jody Salzer
Hi! I'm Jody Salzer and I am excited to teach 4th grade again this year! I love 4th for lots of reasons, one being that the California Social Studies curriculum is something I just love.
5th Grade: Ms. Morgan Holscher
My name is Ms. Holscher and I am so excited to be your teacher. I grew up in this neighborhood, and I am fortunate enough to start my fourth year here at Most Holy Trinity. I have previously taught 5th-8th grade. I believe that it is my job to make sure students excel in their academics, and teach students life skills they can use beyond the classroom. I have a Bachelor's in Liberal Arts with a Concentration in Teaching from San Jose State University, and a Masters of Teaching and Teaching Credential from the University of San Francisco. I have a strong passion for reading, sports, and traveling. I look forward to our year together.
Middle School Religious Studies & Social Studies / 6th Grade Homeroom: Ms. Madison Martin
I'm very excited to be starting my first year at Most Holy Trinity as the 6th, 7th, and 8th grade Social Studies and Religion teacher! I love middle schoolers because they are starting to become more responsible and curious about the world around them, while still soaking in the final years before entering high school. I recently received my BA in History and Secondary Education from Loyola Marymount University, and am currently attending Santa Clara University to receive my MA in Teaching. I am inspired by the commitment to celebrating diversity at MHT, and I am grateful to be coming into such a strong school community.
Middle School Math & Science / 7th Grade Homeroom: Mr. Steve Carroll
This is my second-year teaching at MHT. I received a bachelor’s degree from San Jose State University, and currently working on my MA and teaching credential at University of San Francisco. I grew up in San Jose, and I know MHT has a long history of serving the community. I am grateful to be here.

Physical Education: Karina Ramos
Hi all! My name is Karina Ramos and I am a Jesuit Volunteer at Most Holy Trinity School. I am from Milford, MA and just completed my B.A. in Chemistry and Visual Art History & Theory at the College of the Holy Cross. My role this year at MHT will be a dual collaboration between Physical Education and Assistant Teaching.
While at Holy Cross, I assumed the role of Executive Director for the non-profit Working for Worcester. This role has allowed me to work directly alongside the City of Worcester to build recreational infrastructure within the Worcester Public School well as city public parks and recreation centers. I am so excited to join the MHT team and transition into a more personalized role working alongside students! In addition to academics and service, I am passionate about traveling, playing sports, and literature. I am most looking forward to meeting the impressive MHT team and being a part of such an intentional community driven by the enthusiasm and success of their students. I am honored to be spending this year with you all.
