Karen Will, a Dental Hygienist at the Frank Dental Clinic

Karen Will, a dental hygienist at the Frank Dental Clinic, has been approached by the neighborhood community center to run a "mouth guard clinic" as a fundraiser for children from low-income families to be able to participate in community sports. To draw attention to the event, Karen asks George Prince, a well-known community member who played for the National Football League 20 years ago, to be a spokesperson for the event. Mailbox announcements are distributed to the community announcing the fund-raising event and requesting donations, and coaches are invited to attend the clinic. Karen organizes the free weekend mouth guard clinic with products bought from the fund-raising event; the weekend event is staffed by dental hygiene volunteers from the other dental clinics. Before the event, the community television and radio stations run regular public announcements portraying National Football League players putting mouth guards on during practice and games.
