This year’s Top Young Professionals from the New England region include mechanical, structural and pavement material engineers, a financial innovator and a health care renovation expert. Working for industry employers from Connecticut to Maine, some winners remember setting a career path in childhood, while others recall a professional opportunity that opened a door, and at least one reveals a unique passion that led him to become an entrepreneur.

This year’s winners, each under age 40 as of Jan. 1, were judged by industry experts based on their education, experience, leadership and commitment to community service. The judges were Ariel Greenlaw, traffic, toll and ITS department manager at HNTB, and Ben Markham, president of Acentech.

One New England winner was also placed on the national ENR Top 20 Under 40 list. Steven Vendetti garnered valuable experience working for an international fire protection engineer, and his passion for improving processes prompted him to found a totally remote firm to offer a personalized approach in the field. Vendetti was recognized with all national Top 20 Under 40 honorees during ENR’s Top Young Professionals Conference March 8-10 in New Orleans and will be featured along with the other winners in a cover story in the May 15-22 national print issue of ENR.

Matthew Ciborowski

Matthew Ciborowski
37, Transportation leader seeks to help underserved communities
Associate, Americas East Planning Leader

Matthew Ciborowski believes all members of a design team should share in the responsibility of taking care of a community—especially underrepresented minorities—that is impacted by large projects such as a citywide net-zero plan or small ones like a station renovation.

Before joining Arup, he led major infrastructure and policy projects at the Massachusetts Dept. of Transportation for nearly seven years, including work as deputy project manager on the $1-billion Green Line Extension. In work on that project for Arup, Ciborowski and his team provided technical advisory services, cost estimating and scheduling support.

Much of his project work involved providing advanced strategy. For the South Station Expansion project, he led a team that was able to balance development and rail investment, Arup says. His team also outlined a new route under Boston for the North-South Rail Link as part of the Allston Interchange project.

Community involvement has been part of Ciborowski’s life since his university days. He led a student-run crisis hotline at MIT and still volunteers to help students manage stressors of college life. Today, he is co-chair of the infrastructure committee at the Urban League Institute of Boston.


Amanda Delfosse

30, Young leader embraces construction as a powerful tool for change in health care
Assistant Superintendent

As a leader of best-in-class health care renovations, Amanda Delfosse views construction as a tool to improve the quality of life for communities.

After graduating college, she joined AmeriCorps with a focus on natural disaster recovery. In this role, she trained 27 site supervisors and more than 4,000 volunteers to help rebuild communities. Later, as a project manager for Habitat for Humanity in New Orleans, she assisted flood survivors with affordable housing by overseeing a total of $300,000 in grants and finishing some 50 owner-occupied residential projects. In a 2018 affordable housing initiative, she biked with a team nearly 2,500 miles to raise almost $100,000.

Delfosse now manages the Shapiro Pharmacy renovation at Boston's Beth Israel Deaconess Medical Center.

She has delivered more than a dozen projects for the facility and for Brigham and Women’s Hospital. Delfosse completed her Suffolk project management rotation at the $700-million Winthrop Center Tower.

Throughout her career, she has focused on the definition of community belonging. Delfosse’s belief is that a person’s environment provides the foundation for health and success. Hence, every individual deserves a safe and comfortable living space, she believes.

Delfosse still volunteers with her local Habitat for Humanity chapter, joining others who seek to make a positive community impact through commercial construction and health care facility improvements.
