Equi-librium began in 1982 as Monroe County Riding for the Handicapped. It was started by a small group of dedicated volunteers from Monroe County 4H and the Monroe County Easter Seal Society; it served five children with cerebral palsy and had one instructor. After the merger of Easter Seals of Lehigh and Northampton Counties, the program known as Easter Seal RISE (Riding Instruction for Special Equestrians), serving children in Lehigh, Northampton and Monroe counties. In the 1980''s and 1990's, programs were conducted throughout the Lehigh Valley and the Poconos at various commercial equestrian centers, utilizing these centers' horses and facilities. The program as Easter Seals RISE grew and diversified, added programs, participants and instructors.

In 2001, Easter Seal RISE became Equi-librium, a 501c-3 non-profit organization serving children and adults in Lehigh, Monroe, Northampton, Carbon, Pike and surrounding Pennsylvania counties, as well as western New Jersey. Equi-librium now serves more than 100 participants per week through nine different equine-assisted programs.
