Founder, Chairman & Chief Executive Officer

Gregory H. Sachs

Gregory H. Sachs is the Founder, Chairman and Chief Executive Officer of Sachs Capital Group LP. He is also the founder and former Chairman and Chief Executive Officer of Deerfield Capital Management LLC (“Deerfield”). For over 30 years, Mr. Sachs has been a pioneer in the Asset Management industry with extensive experience partnering both in the US and abroad with “Blue Chip” financial institutions, public and private institutional investors and ultra-high-net-worth individuals (multi-billion-dollar families).

Mr. Sachs received both an M.S. in Quantitative Analysis and Finance and a B.B.A. in Actuarial Science and Quantitative Analysis from the University of Wisconsin at Madison. Upon graduation in 1988, Mr. Sachs joined Chicago-based Lotsoff Capital Management as a fixed income portfolio manager. Shortly thereafter, Mr. Sachs was recruited to serve as Vice President and Trading Manager for Harris Trust and Savings Bank’s Global Fixed Income Trading Division. In this capacity, he was responsible for planning and overseeing all aspects of the Division’s activities including the development of the quantitative strategies used by the group to trade international government bonds, futures, options, and other derivatives.

In 1993, Mr. Sachs founded Deerfield Capital Management with the backing of a Hong Kong based partner. In its early years, Deerfield focused solely on fixed income arbitrage and relative value trading strategies based on the identification of anomalies in global fixed income, futures, options, and derivative markets. From its initial funding of $15 million, the firm surpassed $1 Billion under management within four years. In December 2007, when Mr. Sachs sold his interest in Deerfield and retired as Chairman and CEO, Deerfield’s assets under management were approximately $17 Billion diversified across structured and hedge fund products and managed accounts. The persistent growth and success of the firm during this period is owed to Mr. Sachs’ belief in the importance of three factors: solid returns, risk management and client relations. Mr. Sachs’ success in steering Deerfield from a small fixed income hedge fund manager into one of the industry’s most respected alternative fixed income capital managers is a reflection of his energy, persistence and foresight during a period of great change.

Mr. Sachs created a Fund Administration Company in the Bahamas. The Fund Administration Company managed about $2BB and Mr. Sachs sold it to the Bank of Butterfield (Bermuda) in 2004. In addition, Mr. Sachs was instrumental in creating a Bank in Gibraltar.

While Mr. Sachs was at Deerfield, Deerfield was responsible for managing Deerfield Capital Corp, a publicly traded (DFR:NYSE) specialty finance company that invests in different credit related asset classes, including corporate debt instruments (e.g. bank loans, mezzanine debt, etc.) and mortgage backed securities (e.g. RMBS, whole loans, etc.). Deerfield Capital Corp had gross assets in excess of $8 billion at the time Mr. Sachs sold his interest in Deerfield.

Mr. Sachs founded SCG Financial Acquisition Corp. (SCGQ:NASDAQ), a Special Purpose Acquisition Company in 2011. He raised $80 million through an initial public offering and assembled a team to assist in identifying acquisition targets. SCGQ acquired RMG Networks, Inc. and Symon Communications, Inc. in April 2013 (now named RMG Networks). RMG Networks was publicly traded (RMGN:NASDAQ) until it was taken private in September 2018. As the former Executive Chairman, Mr. Sachs played a critical role in the management of RMG Networks, positioning the company to be a global leader in technology-driven visual communication. Mr. Sachs continues to serve as a board member of RMG Networks.

In addition to institutional investment experience, Mr. Sachs also has significant experience investing in a wide range of asset classes for his personal portfolio, as well as others. These asset classes have included Life Sciences, Quick Service Restaurants, Commercial and Residential Real Estate, Retail and Restaurant, Equity Trading Strategies, Managed Futures and Options, as well as a variety of other Alternative Asset Classes.

Mr. Sachs was an Adjunct Professor at USC Marshall School of Business in Los Angeles, where he taught a course to second year Graduate Students in the Lloyd Greif Center for Entrepreneurial Studies. The course focused on building an Alternative Asset Management business.

Mr. Sachs is happily married, is the father of three children and enjoys travel and cycling. His commitment to philanthropic causes is recognized in the S.A.C.H.S. Foundation, which has sent hundreds of underprivileged children to summer camp. In November 2001, Mr. Sachs was named in Crain’s Chicago Business’s annual “Forty Under Forty” article, which showcases Chicago’s rising business and civic stars. Mr. Sachs has been an invited speaker at numerous international conferences.

Mr. Sachs continues to serve as a board member of the now private RMG Networks, Inc. He served on the Board of Trustees of Chicago’s Shedd Aquarium and was a member of the Business Executives for National Security (BENS).
