MRT’s Team

DJ Jesser, LICSW
Farm Director and Founder

Inspired by her horses and working as a clinical therapist at a public alternative school for students with  emotional behavioral challenges, DJ established MoonRise Farm in 2002. She noticed how horses motivated and encouraged her students to view themselves in a new way. Students saw and were able to practice positive change in their lives through connection with the horses. In collaboration with Vermont Adaptive,  the program grew to serve hundreds of participants with physical, cognitive and emotional challenges. In 2018, she founded MoonRise Therapeutics (MRT), a non-profit community organization focused on mental health and wellness.

In addition to directing and growing non-profit,  DJ is a licensed Independent Clinical Social Worker (LICSW) and offers direct  prevention and intervention services.  Her primary work focuses on anxiety, depression and issues from the impact of trauma and adverse childhood experiences. Her certifications include Gestalt Equine Institute of the Rockies, EMDRIA for level 1 and 2 as well as Equine-Assisted EMDR and PATH Intl (Professional Association of Therapeutic Horsemanship International) Registered Instructor and also Equine Specialist in Education and Mental Health. With forty years of experience in the counseling field, and a lifetime of experience with horses, she continues to share her passion and leadership in this work. On-going goals for DJ are to continue to learn from her horses and support positive and joyful connections of people to themselves, each other and the natural world.

Sienna grew up in San Diego where she began her love of this field while volunteering for the BETH Program in the 80’s and early 90’s. The wonderful people and horses in this program helped shape and support her as she went from a teenager to a young adult. She loved being an assistant coach on the interactive vaulting team and a volunteer in lessons as well as helping out with horse care.  Sienna had the opportunity to work at the neighboring hunter/jumper training barn where she also learned the art of riding over jumps and showing. 

In the late 90’s, Sienna moved to Vermont where she worked for a great eventing barn and loved learning about dressage, riding cross-country courses and stadium jumping. After spending a dozen years in the school systems working with special education, she decided it was time to return to her roots in the therapeutic riding field. She worked for 8 years at High Horses TRP. In 2019, after several years of being a part of MoonRise Farm in supporting their programming, Sienna became an employee there as they transitioned to MoonRise Therapeutics as a non-profit organization. Sienna loves being with the herd and sharing time with others around them. In addition to teaching Horse Connections lessons, supporting the therapists with the horses and giving horse care, Sienna also coordinates the volunteer program at MoonRise.Along with her PATH Intl. certifications of Advanced Therapeutic Riding Instructor, CTRI and ESMHL; Sienna holds practitioner certifications in Equine Experiential Education Association (E3A), Masterson Method Equine Specialist (MMES) and Horse Speak.
