In April 1995, Karsh, Howard Marks, and three other employees at TCW left their firm to found Oaktree Capital Management. Karsh became a portfolio manager for Oaktree's Distressed Opportunities and Value Opportunities strategies and Chief Investment Officer for the firm.

He’s just a solid guy who does his homework and thinks through timing.”
