The Miss Berks County Scholarship Organization sponsored the program, which was held at Wilson West Middle School.
Riley, a senior at Berks Catholic High School, will compete for the title Miss Pennsylvania in June at The Hyatt Regency, Pittsburgh International Airport.
"My platform is 'Project Volunteer: Giving Back to Our Community,' " she said. "I want to show the many different ways that people can volunteer."
Riley said that some people may feel overwhelmed by the thought of volunteering, but giving back to the community can be something as simple as spending an afternoon helping at their child's school.
To advance her aim, Riley plans to visit local emergency shelters to learn their needs.
"I want to help them out by getting volunteers, donations or whatever else they need," she said.
