In the Workplace
Through our commitment of advancing diversity, equity, and inclusion at Thielsch, we are focusing our efforts on the attraction and retention of individuals who have historically been marginalized. In 2021, our CEO and President, Vin Graziano, along with the board of directors put out a further commitment to diversity, equity, inclusion by hiring our first Head of Diversity & Inclusion. This role focuses on ensuring that our workplace acts as a responsible partner both internally and externally by ensuring our workplace, language, and services is reflective of our vibrant community.
At Thielsch Engineering, Inc. (TEI), we are proud champions of diversity, equity, and inclusion for our employees, customers, and our community. Our supplier diversity program demonstrates our ongoing commitment to our vendors, contractors, and suppliers by ensuring that Minority-owned, Women-owned, LGBTQ-owned, and Veteran-Owned enterprises have an opportunity to work with us in meaningful ways.
We hold in high regard being good stewards of the dollars our customers and partners spend with us and are working to ensure those dollars are supporting businesses and individuals who have been historically marginalized, underrepresented, or have experienced barriers in accessing opportunities.

The challenges posed by climate change demand more aggressive actions from individuals, businesses, and organizations alike. We acknowledge that the depleted conditions of our climate, oceans, forests, and other ecological systems on Earth have negatively affected and even displaced the most vulnerable human populations among us. In 2021, our CEO and President, Vin Graziano, along with the board of directors demonstrated their commitment by hiring a full-time Sustainability Analyst to conduct non-financial accounting of our energy source and consumption, greenhouse gas emissions, water use, and waste generation. Thielsch takes the position that human activity has caused climate change and that “waste” should be viewed as a resource that can be managed within a circular economy.
