  • Monica Christensen

    Dean of Students
    mchristensen@msmnyc.edu

    I worked at MSM for most of the 1990s, and returned in January 2015 — There is something very special about this place! I graduated in Asian Studies from Dartmouth College, and earned a doctoral degree in Higher and Postsecondary Education from Teachers College, Columbia University, where I’ve been a faculty member since 2000, and teach part-time. My husband and I are very proud of our three young adult children who were raised in Brooklyn but are now scattered across the country. When I am not busy “deaning” or teaching or being with family, I enjoy cycling, reading, and gardening.



  • Melanie Dorsey

    Director of Student Engagement & Deputy Title IX Coordinator
    mdorsey@msmnyc.edu

    I joined Manhattan School of Music in the spring of 2004 as Assistant Director of Student Life, arriving here with a strong love and respect for the arts, having studied interior design and art history at Appalachian State University, in North Carolina. In 2020 I completed my Master’s degree in nonprofit management at The New School right here in New York City. I enjoy making genuine connections with students and supporting their personal development outside of the classroom. I live in Brooklyn with my partner Jamie and rescue cat Nima. In my spare time, I enjoy volunteering in my community, seeing movies, and baking treats for friends!

  • Kai Santiago

    Student Engagement Coordinator
    rsantiago@msmnyc.edu

    I am a Bay Area native from Daly City, California who moved to New York City to pursue a MA degree at Teachers College, Columbia University in Higher and Postsecondary Education. While in the program, I was the Graduate Assistant for Student Engagement for the 2020-2021 school year at MSM. Prior to my time in New York City, I received my Bachelor’s degree in Psychology from San Francisco State University in 2017. With my background in Psychology and Higher Education, I am passionate about student leadership development and ensuring that students feel a sense of belonging on campus. In my free time, I am a freelance makeup artist who enjoys cooking traditional Filipino dishes and singing karaoke (I’m a tenor!)
