Our CEO
Gary I. Leff has over 45 years’ experience in the real estate business, including leasing, financing, management, construction, development, acquisitions and dispositions. Over the years, Mr. Leff has developed, acquired and/or sold nearly 4 million square feet of commercial, industrial and residential real estate properties, primarily in Southern California, but also in other regions of the Western U.S. Mr. Leff began his career as a general contractor and developer of single family homes, and eventually expanded his enterprise into the development and management of industrial-office complexes, mid-rise office, retail, automotive centers, and self-storage facilities. As his portfolio grew, Mr. Leff founded Mid Valley Properties, Inc., which has become a full-service property and asset management firm for his real estate projects and other select private investors’ portfolios. In the mid-1990’s, Mr. Leff together with other investors, acquired ARCS Commercial Mortgage, LLP (then a subsidiary of the Bank of New York), and successfully built ARCs into a nationwide provider of multifamily commercial property loans, achieving recognition as the top loan originator nationwide within Fannie Mae’s underwriting program and earning the reputation of being the largest apartment lender in the country. In 2009 Mr. Leff founded Partners Capital Solutions, a direct lender that provides customized debt financing solutions to real estate professionals, identifying and capitalizing on a market opportunity due to the lack of traditional financing sources at that time. The Fund has deployed more than $2.2 billion of commercial real estate loans since inception. Mr. Leff has also invested in numerous other business ventures that reflect his personal interests ranging from telecommunications, to transportation, athletic facilities and private aircraft. Mr. Leff received his bachelor’s degree from California State University at Northridge.
