Cotton Creek Capital, a Dallas-based private equity firm focused on lower middle-market companies, said it promoted Lee Rash to vice president.

Rash joined Cotton Creek Capital in early 2012 and is responsible for evaluation and execution of investment opportunities, as well as post-closing and operational initiatives with several of Cotton Creek’s portfolio companies. Prior to joining Cotton Creek, Rash was an associate in the Mergers and Acquisition Advisory Group at New York-based, Blackstone, a large-cap private equity firm.

“Cotton Creek is excited to promote Lee to vice president in recognition of his contributions to the firm, as well as the continued growth of Cotton Creek,” said Antonio DiGesualdo, managing director of Cotton Creek.
