CoreSource Announces New Facility for Lancaster, Penn., Office


LAKE FOREST, Ill. – CoreSource, a leading third-party administrator (TPA) of self-funded employee benefit plans, announced today that its Northeast Region headquarters in Lancaster, Penn., will move to a new facility just a few miles from its existing home. In the summer of 2010, the company’s approximately 300 local employees will move from their longtime home in downtown Lancaster to a modern 50,000-square-foot development in the historic “Stockyards” area of Lancaster.

“CoreSource has been a proud member of the Lancaster community for more than 30 years, and we look forward to building a new history in the Stockyards,” said Chip Sernyak, Regional President, Northeast, CoreSource. “This new building will allow us to more effectively meet the needs of our growing client base and stay connected to the rich history we have in Lancaster.”

The Lancaster office is one of the largest in the CoreSource family, which encompasses nine client service offices around the country. They administer medical, dental and vision benefits for more than 200,000 employees, dependents and retirees in Pennsylvania and other Northeast states. Lancaster is also home to CoreSource’s nationally renowned healthcare management division, which provides care management services to more than one million employees and their dependents nationwide.

CoreSource’s roots in Lancaster date back to the 1970s. Today, it is a source of employment for residents of Lancaster County.  “We have enjoyed our current space in downtown Lancaster, and truly appreciate the great opportunities and experiences the city has to offer. While the physical space we’ve been in simply can no longer meet our needs, the workforce in this area is among the best in the country,” Sernyak said. “Our employees are proud to deliver our clients the best customer service in the employee benefits industry, and we plan to continue doing business in Lancaster for a long, long time.”

While the building initially will be approximately 50,000 square feet, it will be able to handle an expansion of nearly another 10,000 square feet – an expansion CoreSource believes is bound to happen given the company’s current position. “Despite the uncertainty in Washington around the future of the U.S. healthcare system, CoreSource is well positioned to continue our track record of sales growth,” said Paul Lotharius, CoreSource President & CEO. “We’re growing, and we’re very proud of the fact that our Lancaster office will be a big part of that growth in the years to come.”
