Supplier Diversity and DE+I
Ensuring diversity, equity, and inclusion (DE+I) is a top priority at HITT. We’re committed to creating a sense of belonging where everyone is welcome.
It’s important to HITT that we continually increase subcontractor and supplier diversity to ensure representation of minority- and women-owned businesses. By establishing better relationships with underrepresented firms, we hope to provide our partners business opportunities that will help them to grow and advance their firms.
If you are a small, minority- or women-owned firm and would like certification help, please contact Jennifer Parker.
Celebrating Our Trade Partners
We celebrate the hardworking subcontractors who bring their knowledge and experience to each and every project we build together. HITT is deeply grateful for the craft workers who are dedicated to a job done exactly right.
