For over 45 years, the organization has provided a forum for business leaders to problem solve, collaborate, and obtain advice on critical issues facing their businesses.

The organization is headquartered in, and advocates for, the Long Island Innovation Park at Hauppauge (LI-IPH), one of the largest industrial parks in the Northeast, with over 55,000 employees and 1,300 companies giving back over 13 billion in economic output. Through a sustainability study performed by the Suffolk Industrial Development Agency and the Regional Plan Association, the LI-IPH represents 58 percent of tradeable sectors on Long Island, infusing dollars into the local economy, deeming it a major economic hub. Under Alessi-Miceli’s leadership, HIA-LI is playing a vital role in combatting Long Island issues such as transportation, workforce development, and affordable living in the Innovation Park.

HIA-LI also hosts the Annual Business Trade Show and Conference, which sets records for business participation and is a major economic engine on Long Island.
