Covering seven square miles of Lake County, IL, Aptakisic-Tripp School District 102 serves over 2,500 students in four schools – Tripp Elementary School, Pritchett Elementary School, Meridian Middle School, and Aptakisic Junior High School.

GSF ILLINOIS began working with the district in 1998, and in 2005 formalized a long- term partnership. Today, GSF ILLINOIS empowers a team of over 20 full-time staff to maintain all of the district’s facilities — cleaning carpets, floors, windows, and other surfaces to ensure each building is sanitary and orderly for the next school day.

GSF’s innovative Écologique cleaning program brings together sustainable chemicals, equipment, consumables, documented training and procedures, and GSF University leadership development to help the district reduce its environmental impact. The program, which is certified by Green Seal, ensures the highest standard of cleanliness to benefit students, staff, and visitors.

Jose Acosta, Account Manager, has been with GSF ILLINOIS since 2016. Under his leadership, Jose has forged an outstanding relationship with the district’s administrative team and with the local school facilities managers to elevate and maintain exemplary levels of service.

As a global leader in the flavor and fragrance industry, Mane opened its North American headquarters in Lebanon, Ohio in 2014 — an award-winning 85,000 square-foot building that houses its corporate headquarters and state-of-the art R&D center.
