Gretna Theatre has been presenting outdoor summer plays and musicals for 94 years in the open-air Mount Gretna Playhouse, which dates back nearly 130 years. When the theater company had to scrap most of its 2020 season because of the COVID-19 pandemic, its executive producer, Lancaster native Brian Kurtas, was determined to make sure the theater would be back this year to continue the nearly centurylong tradition. âIn February and March of 2020, we made a commitment that we werenât going anywhere,â Kurtas says. âWe have offered an adaptation of what we would normally be able to serve the community, in terms of both artistic programming and also educational programming.â
