Prosek Partners has acquired Los Angeles-based corporate communications and investor relations agency Muirfield Partners.

Financial terms of the deal were not publicly disclosed.

Prosek Partners

Muirfield, which represents clients in the asset management, investment banking, private equity, tech and real estate sectors, was founded in 2001 by president Mickey Mandelbaum. A former general manager at tech and digital PR firm Connors Communications, Mandelbaum was also previously VP of corporate communications at European banking group Banco Santander and served as an associate at New York-based corporate and crisis communications firm Kekst and Company.

The deal gives New York-based Prosek its first West Coast outpost. Muirfield’s Wilshire Blvd. offices will remain in operation under the Prosek name. Mandelbaum now takes the title of Prosek partner.

Prosek last year added Andy Merrill, former senior managing director at global strategic consultancy Teneo, to the agency’s partner roster as well.

"Muirfield gives Prosek a top-notch financial communications team on the West Coast that shares our vision and values,” Prosek Partners managing partner Jennifer Prosek told O’Dwyer’s. “This will benefit our clients with West Coast needs and will also bolster our transactions and special situations capability across the firm."

Prosek Partners, which specializes in financial, healthcare and professional services PR, in 2015 accounted for $24.4 million in net fees, according to O’Dwyer’s rankings of PR firms, revealing 20 percent year-over-year growth from 2014.
