AUSTIN, Texas -- Power for Parkinson’s has a lot to celebrate on its fifth anniversary, and on Sunday the organization threw a party.

Two Austinites launched the nonprofit, which offers free exercise classes to people suffering from Parkinson’s and for those caring for them.

For the five-year milestone the organization is celebrating the eleven free classes they offer each week.

"We're celebrating because people are getting better, people have hope, people come out of their houses and connect with each other and that's what we're celebrating,” said Susan Stahl, PFP co-founder.

"As an instructor it's just so much fun to watch because a normal fitness class everyone is either beginner, middle, or advanced and this [one] everyone is able to do what they want, whatever they're capable of doing at their best and just have some fun with it." said PFP fitness instructor Lauren Lewis.

Classes are offered at eight different locations from south and central Austin to Round Rock and Lakeway. Sunday's event was free and included dance performances by the PFP dance troupe, exercise demonstrations, dinner, and live music.
