Principal and Co-Founder

Adam A. Arnow has managed direct real estate investments made by the Arnow Family and several other high-net-worth families in properties in the northeast region of the United States and Ireland throughout his career. Beginning in 2005, Adam spent seven years managing acquisitions at Olmstead Properties, Inc. – a family-owned real estate owner / operator (not the Arnow family) based in NYC. In 2012, Adam began actively investing in direct real estate deals primarily on behalf of his family, in partnership with other families and institutional investors such as JP Morgan and Oaktree Capital Management. Since 2005 Adam has managed transactions valued in excess of $1.5 billion.

By way of background, Adam’s family has been in the real estate business since the 1930s. The Arnow family has developed over 10 million square feet of office and residential properties throughout the United States, but primarily in New York City - including the Grace Building, 1411 Broadway, 711 Third Avenue, 437 Madison Avenue, 7 Hanover Square, and 250 Mercer Street. While the family continues to own a portfolio of legacy assets, most of the Arnow family portfolio was sold in 1997 to a Real Estate Investment Trust called Trizec Inc.

While Adam’s initial investments were in NYC they have expanded to include over a dozen projects in Ireland, and several multi-family development projects in and around Boston, MA and Pittsburgh, PA.
