McKeever joins the agency's London office next week as senior associate. His clients at Luther have included National Grid Property and Baxter Healthcare. He also led lobbying efforts for white-goods trade body the Association of Manufacturers of Domestic Appliances.
Before Luther, McKeever was comms consultant for property development firm Bee Bee Developments, which is a specialist in urban regeneration.
His arrival follows APCO's appointment last month of Paul Feldman, former US Federal Aviation Administration director for EMEA, as a director in its Brussels office. Feldman will support the agency's international transportation clients.
