Known for its commitment to quality, Decron Properties Corp. owns and manages real estate. While most of the firm’s holdings are located in Southern California, the company also maintains out-of-state properties that correspond with its sensible land use policies. Founded by construction professional Jack Nagel, Decron Properties diversified its portfolio in the 1970s and 1980s to include multifamily and commercial projects. Today, Mr. Nagel serves as the company’s chairman, while his son, David, oversees daily operations and long-term planning as the president and CEO.
