Committed to our Community

The WT Group believes that helping to build the community is a mission that extends beyond simply providing market-leading design and engineering services. It also means connecting with community leaders, nonprofits and charities that make a difference in the lives of people every day.

The WT Foundation

Cultivating talent to help build the future

At the heart of our company’s commitment to the community is the WT Foundation, which promotes the development of new talent in the field of engineering through educational assistance and scholarships to prospective engineering students.

Scholarships are given each year to a graduating senior pursuing a college degree in engineering from the District 211 High Schools of James B. Conant, Schaumburg, or Hoffman Estates. The WT Foundation also grants scholarships to a child of a WT Group employee.
