  • 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 children we raised in Brooklyn, who are now on the cusp of adulthood! 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

    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. I’m now completing a Master’s degree in nonprofit management at The New School here in New York City. I enjoy making genuine connections with students and contributing to their personal development outside of the classroom. I live in Brooklyn with my rescue cat, Nima. In my spare time, I enjoy volunteering in my community, seeing movies, and baking treats for friends!

  • Samantha Tymchyn

    Director of Residence Life

    Originally from Upstate New York, Samantha earned her Master’s degree in Higher Education from Columbia University, Teachers College and her Bachelor’s degree from Siena College. Rooted in college student development, Samantha is passionate about engaging students at MSM outside the classroom and enriching their residential experience. Samantha enjoys spending quality time with friends & family, traveling, and cooking up something new with fresh ingredients from the local farmer’s market.

  • Crystal Wilson

    Assistant Director of Student Engagement & Coordinator of Disability Services
    cwilson@msmnyc.edu

    I joined the MSM Student Affairs team in 2016 after completing my master’s degree in Higher and Postsecondary Education at Teachers College, Columbia University. I came to New York by way of California, South Africa, and Vietnam — where I spent 5 years as an ESL instructor. I enjoy advising student organizations, helping students develop leadership skills, and contributing to a more connected MSM community. I love to hike, swim, jump rope, try new foods, learn languages, and explore other cultures.

    Housing Operations Coordinator

    Celine is brand new to MSM and is excited to take on her new role as the Housing Operations Coordinator. Celine graduated from Indiana University of Pennsylvania with a Master’s degree in Student Affairs in Higher Education. Prior to joining the MSM community, Celine served as the Student Conduct Graduate Assistant at the University of Pittsburgh Johnstown. Before starting graduate school, she worked full time as a Resident Director at Juniata College and also worked part time for Columbia’s Summer Program for High School Students. Celine is passionate about working with students and helping them make a positive contribution to their campus community. Celine is originally from Mandeville, Jamaica and misses the mountains and tropical weather, but she loves New York City (NYC) and is happy to call NYC home.
