It's never too soon to start thinking about summer musical theater opportunities. Below are some options in the Philadelphia region that I recommend to my students. Please note: There are many other programs around, but these are few that I recommend based on many factors, including: my knowledge of the programs, their instructors, or reputation; my students' experiences; or my own experience as an acting student.
Barley Sheaf Players (Lionville, PA)
Barley Sheaf is a community theater that produces a full season of shows during the year and runs two shows - one for teens, one for kids - during the summer. This year's teen show is Addams Family. Teens are strongly encouraged to attend the Teen Show Audition Workshop to help them prepare. The kids' show will be announced at a later date. Please note that Barley Sheaf's summer programs are practically free (participants pay a small fee of about $25), but acceptance is quite competitive.
West Chester Studio for the Performing Arts (West Chester, PA)
Director Therese Walden-Murphy has acted on Broadway and in L.A., and she is an excellent teacher of acting and musical theater. Sign up early, as sessions fill up quickly!
West Chester Summer Stage (West Chester, PA)
WCSS gives students the experience of performing in a high-quality musical theater production. (I have attend several excellent performances there.) However, my impression is that the program is quite large and doesn't offer a lot of individual attention to each student. Also, opportunities tend to go to kids who have been longtime participants.
Walnut Street Theatre (Philadelphia, PA)
As Philadelphia's center for professional musical theater productions, the Walnut offers excellent programs for kids, teens, and adults. Offerings range from beginning acting to advanced musical theater, with additional classes in storytelling, auditioning, and on-camera technique. Some classes may require auditions.
Upper Darby Summer Stage (Upper Darby, PA)
UDSS has an wonderful reputation as a NY-style theater camp. (Tina Fey is a graduate.) Previous seasons have included six children’s theater shows and a mainstage production of a Broadway musical.
