Denver-based Janus Capital Group Inc. has made two senior-level hires to beef up its client relations team.

Andrew B. Weisman has been appointed senior vice president, leading the development of JCG’s alternative and multi-asset client solutions, reporting to CEO Richard M. Weil.

Soonyong (“Suny”) Park has also joined the firm as an institutional client strategist, reporting to Susan Oh, Head of the U.S. Institutional Group. Both roles are new to the firm.

Prior to joining JCG, Weisman was a partner at WR Platform Advisors, Inc., a technology platform and service provider of managed accounts, risk analytics, and investor reporting for hedge funds. Previously, he served as chief portfolio manager for Merrill Lynch’s Hedge Fund Development unit.

Park most recently served as co-Head of Research at consulting shop Rogerscasey, where he led institutional thought leadership on topics such as strategic and tactical asset allocation, plan structure, governance policies, and manager research.

“Attracting investment industry experts and thought leaders such as Andy and Suny represents our continued focus on providing leading-edge talent, strategies, and risk management solutions for our clients,” stated Weil.

Janus managed $164 billion as of the end of March 2012.
