A Parkville Irish dance school is hitting the local pub and restaurant scene this St. Patrick's Day weekend, performing at dozens of locations across Baltimore and Harford counties as part of an annual fundraiser. The Doherty Petri School of Irish Dance, founded in 1991 by sisters Karen and Lisa Petri, has grown into a nationally recognized program with locations throughout the United States and Ireland. The school's most recent location opened in Parkville, Maryland, just over 3 years ago. #irishdance #parkville #stpatricksday
