Mrs. Wagner founded Opportunity Acres in 2013 in response to a clear need for better services for adolescents and adults diagnosed with Autism.  After spending so many years in the field and watching some of her very first clients enter adulthood only to find there were no specialized supports, she decided to stretch and grow as a professional and begin and Adult Day Program (ADP) and Non-Public School for middle school and high school students. The vision for this project was to give these individuals a very special environment and Opportunity Acres is just that.  This 56 acre ranch is buzzing with visitors, horses, sheep, goats and a donkey and a motivated clinical team working to change lives every day.

Most importantly, Mrs. Wagner is the mother of three children, Jake, Gavin and Morgan who have taught her what parenting is really about.
