Company founder Henry Hill began building houses in and around Will County, Illinois in 1995. He assumed much leadership and business control from his Father, Robert, and Grandfather, Marion Hill, from their experiences of operating a multitude of successful construction and development businesses together beginning in 1958. Both of them urged Henry to complete his engineering education in the late 1990’s, and to build a business from the beginning, so in 1997 Henry started reaching into residential work and began expanding his focus into non-residential construction.  He incorporated Marion Hill Company in 2003 after the successful completion of the company’s first several commercial projects.  Henry eventually started to diversify and the resulting organization went on to start building an impressive portfolio of senior nursing, senior living, retail, institutional, industrial, manufacturing, civil, and municipal project experience.

Henry then decided to bring partners into the business in order to increase its financial stability and wealth.  Marion Hill Company, along with several other small businesses, were sold to the new partnership and in 2012 Mack Construction Corporation was incorporated as a sum of all of Henry Hill’s parts and the small group of investors.  By 2015 the corporation’s revenue had grown by more than 1000%.  Henry took that success and bought all the company shares from the investors taking sole ownership in 2015.  Henry changed the name of the company to Lenox Hill Construction and the organization has not looked back.  The core management philosophy is to maintain honor and integrity throughout all the various phases and inevitable challenges any project presents.  These principles are demonstrated daily by the company management team that Henry started putting together in the late 1990’s.  Every major management role within the organization is held by someone with a minimum of 12 years of experience working with Henry Hill.
