Citizens Bank recently financed the merger of four veterinary practices into one group based out of Woburn with a $21 million credit facility.

Ethos Veterinary Health provides specialty and emergency care for pets through a network of 13 hospitals across the United States. It recently formed as the result of a merger among four specialty hospital groups: IVG Hospitals in New England, Premier Veterinary Group in Chicago, Wheat Ridge Animal Hospital in Denver and Veterinary Specialty Hospital in San Diego.

“Ethos Veterinary Health is an excellent client and we’re very happy to be able to offer our industry expertise as well as our capital markets capabilities to help them achieve their strategic and financial goals,” Jerry Sargent, head of middle market banking at Citizens Commercial Banking, said in a statement.

According to the statement, the merger has been many years in the making.
