About Us

Greystone Manor TRC, a 501(c)(3) organization, has been providing quality equine-assisted activities to children and adults with special needs in Lancaster, PA, since 1981. Every year our program and number of participants grow. We started with only seven riders and now more than 50 riders participate in lessons each week.

In addition to riding lessons, we offer a monthly unmounted clinic series for individuals who want to learn more about horses from the ground level.

Our riding lessons and clinics are goal-oriented to meet the individual’s personal needs. Each participant is assessed prior to lessons and goals are developed.

Throughout the world, hundreds of thousands of individuals experience the rewarding benefits of equine-assisted activities. Cognitive, physical or emotional special needs should not limit a person from interacting with horses. Such interactions can be highly rewarding.

With volunteer help, individuals with special needs can become increasingly mobile, learn a degree of control over a responsive animal, and grow in self-esteem. They can also learn to care for the horse and create a special bond with them.
