Los Angeles, London and Toronto-based film financing company Grosvenor Park has named Joseph C Kaczorowski partner and David Alper principal and COO.

Kaczorowski most recently served as president of House Of Blues Entertainment, while Alper most recently managed Relativity Media's single-picture equity financing and production business.

Backed by a New York-based alternative asset management firm, Grosvenor Park has funded more than 40 single-picture deals valued at approximately $300m since it moved into its Los Angeles headquarters two years ago.

Kaczorowski previously served as senior vice president and CFO at The Cannell Studios, a supplier of dramas to the networks.

Prior to Relativity, Alper served for five years as CEO and co-managing partner at Escape Artists, which produced The Pursuit Of Happyness. Prior to Escape Artists, he served as co-head of business affairs at New Line and held senior executive posts at Lorimar Motion Pictures and Universal Pictures.
