    Marco Capital Group is a privately owned investment partnership operating in Texas, Oklahoma and the Southwestern United States. Marco and its predecessor entities were established in 1989 to focus on the purchase of real property from the Resolution Trust Corporation. Since that time, Marco has expanded its focus to include private equity and to a limited extent, venture capital. Marco also maintains a core holding of publicly traded securities. Marco seeks to invest its capital in situations that offer the opportunity for returns significantly in excess of those available in the public markets.
