Arthur Brown and Kashif Hussain are now principals based in Beverly Hills, while Daniel O'Connor is a principal at the Denver branch. Brown is an accounting and audit professional at Rothstein Kass Financial Services; Hussain is from the Rothstein Kass Commercial Services Group, while O'Connor is from the Financial Services Group.

In other promotions, Henry Jia, from the Financial Services Group, and Robert Levin, from the Rothstein Kass Family Office Group, have been made senior directors at the firm. 

The appointments follow a recent study by Rothstein Kass, which reveals that family offices are becoming more involved in alternative asset classes such as hedge funds and private equity. According to the research titled, Raising Capital from Single-Family Offices - Considerations for Financial Firms, investible assets of single-family offices have gone up from $236 million in 2010 to about $416 million in 2011. Around 85 per cent of these are currently invested in hedge funds, while around 50 per cent are active in private equity. 

The company is involved in both classes through its various businesses: the Rothstein Kass Financial Services Group, the Rothstein Kass Commercial Services Group, the Rothstein Kass Private Equity Practice, and the Rothstein Kass Family Office Group.
