Ironstone Farm and Challenge Unlimited

Our Mission Statement

To provide therapeutic, educational and recreational opportunities using horses and the working farm environment to help people achieve optimum quality of life.

Ironstone Farm and Challenge Unlimited


We use the dynamic power of horseback riding and the environment of a farm to combine several therapies into one highly effective experience. Top doctors and medical institutions refer clients to Ironstone because of its success.

Children with special needs learn to walk. People who did not speak before – including those on the autism spectrum – begin speaking. Additional therapeutic programs improve the lives of others, including veterans returning with post-traumatic stress, survivors of cancer, teens at risk and elders with memory issues.

Coming to the 18-acre horse farm, rather than an impersonal clinic, makes therapy a “want to” event rather than a “have to” session.

About 200 volunteers each week come and support our therapeutic riding programs because they know their donated work changes lives.
