Meet The Team
Sarah Mosden
Owner, Founder, Music Therapist
My name is Sarah Mosden, and I am the owner, founder, and head music therapist of Mosden Music Therapy, LLC! I became a board-certified music therapist in February 2021. I hold a masters degree in music therapy from Temple University, as well as a bachelor's degree in music education from the University of Miami. I completed my music therapy internship at an arts-focused childcare center in New Jersey (now under new management). I originally became interested in the field of music therapy after working as a music specialist at Sunrise Day Camp; a full-summer day camp for children with cancer and their siblings.
I started my private practice venture in early 2021, shortly after I received my board certification. Not being interested in many of the jobs available at the time, I began reaching out to a handful of schools and facilities to set up (what I thought at the time would be) short-term contract work. I quickly came to realize that many of these centers, especially those for children with diverse needs, were severely lacking in high-quality and interactive music programs provided by a music therapist. I decided to continue my outreach to multiple centers in the area in an effort to provide the best possible music programs to as many children as possible. My ultimate goal is to provide affordable and accessible music therapy services to children in greater Philadelphia area.

Macey Roberts
Music Therapist (South Jersey, Bucks County)
Macey Roberts is a Board-Certified Music Therapist from South Jersey, who earned her Bachelor's of Music Therapy degree from Temple University with a piano concentration in 2025. During her undergraduate studies, Macey actually completed her second practicum placement and 1,000-hour internship at Mosden Music Therapy, working alongside Sarah. Now, returning in 2026 as a Music Therapist feels like a full circle moment, and she can’t wait to support her own clients in working on their goals and discover what they’re capable of through music and a safe client-therapy relationship.
​
Macey’s clinical background includes group work in mental health, alternative and public schools, and a pediatric nursing facility. Additionally, she has experience in settings serving children with emotional and behavioral disorders, at-risk youth, a day camp for cancer patients and their siblings, and neuro-rehabilitation.
​
As a music therapist, Macey’s approach is grounded in iso-principle and humanistic philosophy. She believes musical interactions in session should be individualized and tailored to the client at that moment. Doing so allows her to address immediate needs, supporting engagement and creating a safe therapeutic environment.
