NEW YORK—CJP Communications, one of the leading independent financial public relations firms in the US, has changed its name to Prosek Partners.

The US firm, previously known as Cubitt Jacobs & Prosek, has also terminated its relationship with onetime UK partner Cubitt Consulting. The firm has opened its own wholly-owned office in London to provide clients with international reach.

Chief executive Jen Prosek says that more than 40 percent of the firm’s domestic clients “tap us for work outside of the United States,” and 20 percent are non-US companies. “To support our global client base, we wanted a single name we could use worldwide.”
