As chairman of The Molasky Group of Companies, Irwin Molasky built Las Vegas' first master-planned community (Paradise Palms) and high-rise office building (the 17-story Bank of American Plaza), as well as the Nathan Adelson Hospice. Additionally, Irwin helped find the right location for the McCarran International Airport and assisted with the land purchase for the Las Vegas Convention Center. Through The Molasky Group of Companies, he built the Internal Revenue Service Headquarters and Social Security Administration building in Las Vegas, along with many other great achievements in real estate and development. Like Sam Lionel, Irwin is also known for his philanthropic efforts throughout the state of Nevada. Although Irwin passed away in July 2020, his legacy lives on in many ways – including through the work of Project REAL.
