Peirce College (PA), which largely serves adult learners in Philadelphia, has tapped a New Jersey college administrator as its new president. Mary Ellen Caro, 64, currently serves as vice president of enrollment management and learner services at Thomas Edison State University in Trenton, N.J., which also largely serves adults. Caro, who has been at Edison since 2004 after a 25-year career in business, will replace James J. Mergiotti, who is retiring after nine years at the helm. She is the first female president in Peirce’s 153-year history. She starts April 16.
