Rittenhouse Book Distributors has been acquired by two private investors. The King of Prussia, Pa.–based health and medical content distributor was bought by Kevin Ream and Jeff Villwock.

According to a release announcing the deal, Ream, who is now Rittenhouse chairman, is an entrepreneur with experience “in business development and in increasing revenues using innovative marketing initiatives.” Among his investment holdings, the release said, are a wine brokerage and distributor and several online businesses, as well as investments in book publishing. Villwock, the new Rittenhouse CEO, has more than 40 years of experience in investment banking; his specialties include the healthcare field.

According to the release, the men will focus on expanding Rittenhouse’s digital delivery abilities, now housed in its R2 Digital Library e-book platform. “We are transforming the existing wholesale business with more inventory and faster delivery. We are creating new mobile technologies that will provide instant access to information and resources from our partners,” Ream said in a statement.

Founded in 1946, Rittenhouse works with more than 500 publishers to distribute their intellectual property to thousands of university bookstores, libraries, and healthcare providers.
