“If there is one word that describes Altieri and what we are known for, it is creative. Our success designing building systems for iconic cultural, educational, and historic buildings is the result of a deeply rooted culture of creativity. Being creative – investigating alternatives, determining the best solution, being inventive and innovative – is what I want to be doing every day and is what I like most about working here.”

Our employee-led Initiative Teams Program harnesses the power of an all-hands-on-deck approach to the continuous evaluation of firm practices, direction, and culture. In collaborative teams, employees consider important issues ranging from education and training to design standards. Team USA (United Strengths of Altieri), for example, supports our firm culture with a variety of initiatives focused on diversity, equity, inclusion, and employee engagement. Our respect for diverse perspectives, expertise, and experience keeps us at the top of our game – nimble, imaginative, and innovative.

“The John L. Altieri Memorial Scholarship, established in 2022, honors the founder of Altieri, a man whose immense talent and vision inspired all with whom he worked to reach their highest professional achievements. John’s philosophy and approach, embodied in our Core Values, continue to be the drivers of our firm’s success. Each year we look forward to presenting the scholarship award to a high school senior in the Norwalk Public Schools who intends to study engineering in college and exhibits our core values. It is important to us that we continue to honor John’s legacy by supporting deserving students in our community as they begin their path in the engineering sciences.”
