It is the first time the holiday business has appointed an agency.
Golley Slater’s Leeds team will work on campaigns to raise the profile of Park Leisure and its 11 locations across the UK.
The agency’s first job is to handle comms around Park Leisure’s recent £15m acquisition of Plas Coch Holiday Homes in Anglesey.
Golley Slater will report to head of marketing Grant Gidman, who said: "This is a very exciting time for our growing business and so we needed to bring in a strong PR team with local and national media clout that could really bring to life our offering: making a luxury leisure lifestyle an affordable reality."
Eileen Stretton, managing director, Golley Slater North, said: "In addition to the national capability of our locally based team in the north, the client has the unique opportunity to use the Golley Slater regional network. For multisite businesses this means PR and marketing experts can be close to their locations across the UK."
Last month Golley Slater's northern office won a pitch to manage the consumer and corporate comms for discount retailer Poundstretcher.
