About Us

Therapy, Recreational, Educational and Exploration opportunities for individuals with disabilities and their families.

All in one location.

Nested on more than 88 acres in western St. Charles County, TREE House of Greater St. Louis is a unique and welcoming place where individuals with disabilities and their families can find acceptance, tackle mental and physical challenges, and express their spirit in a peaceful and natural setting.

Founded in 1975 and formerly known as Therapeutic Horsemanship, TREE House is one of the oldest and most respected therapeutic riding centers in the United States. Programs serve clients from age 2 through adulthood who have physical, mental, emotional, social, and/or learning disabilities.

Disabilities served include, but are not limited to, autism, cerebral palsy, Down syndrome, muscular dystrophy, multiple sclerosis, epilepsy, mental and physical disabilities, traumatic brain injury, and more. TREE House operates year-round and relies heavily on the support of volunteers. MORE ON PROGRAMS>

Our History

Formerly known as Therapeutic Horsemanship, TREE House of Greater St. Louis is the legacy of a visionary commitment from three extraordinary St. Louis women – Susie Duesinger, Sandy Rafferty and Laura Carpenter Balding – who began the program in 1975 because they believed in the benefit of equine-assisted therapy for children with disabilities. The organization has accomplished much over its 40+ year history growing from five riders the first year to now serving more than 300 individuals annually. During the early years, TREE House leased several different sites, including Three Creek Farm in St. Charles County and Wessel Stables in Weldon Spring. In 2005, the organization moved into its current facility, which is situated on 88 acres in Wentzville, Missouri.

What started out with borrowed horses in a friend’s barn, has evolved into a state-of-the-art, 88 acre facility and a herd of 27 specially trained therapy horses. The TH team of 250+ volunteers, therapists and horses have served more than 3,000 people with disabilities in St. Louis and five surrounding counties.

In 2014, Therapeutic Horsemanship officially changed its name to the TREE House of Greater St. Louis. TREE stands for therapy, recreation, education and exploration – the four main branches of the TREE House. Our goal is to expand programs and services in these four areas to fill the current gap of services and recreational activities in the greater St. Louis area for children, adults, and veterans with disabilities. Our therapeutic riding program remains the cornerstone for all future expansion.

In 2018, we are celebrating our 44th year of serving the Greater St. Louis Community!  The video at right explains the history and development of our organization and describes how what we do changes the lives of so many children and adults with disabilities each year.
