Abington Health and Holy Redeemer Health System announced that they intend to join forces in a new regional health system, a move the two systems hope will prepare them for the healthcare industry's uncertain future. Abington, which also owns Lansdale Hospital, and Holy Redeemer have "complementary services and skill sets," said William Aaronson, a healthcare expert at Temple's Fox School of Business. "But any time you merge two organizations, you've got a marriage of cultures. Sometimes, they work out. Sometimes, they don't."
