Management


Since our founding we have paired business experience with investment experience.


  • We believe that producing superior investment results requires dedication, focus and creative thinking. Therefore our business management efforts are led by a group of business professionals that are distinct from our investment management leadership in order to provide our investment professionals with the freedom to focus exclusively on their craft.

  • Our team of executives has significant experience in the investment management industry and understanding the needs of institutionally-oriented investors.
