The ENR New England Top Young Professionals selected for 2024 represent the cream of the crop in the region’s construction sector. Their energy, vision and sharp analysis are elevating the industry and bettering their communities. Each of the 10 individuals chosen this year from a pool of dozens of candidates has a unique skill set based on the career paths they have followed.

Working across the region—which includes Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont—the winners were all under age 40 as of Jan. 1.

A panel of industry leaders made the selections based on the experience, education, leadership and community service of the candidates. Choosing the winners was no easy task for this year’s judges: Manny Hoyo, senior superintendent at Boston-based Skanska USA Building Inc., and Ariel Greenlaw, HNTB traffic, toll and ITS department manager.

One New England winner—Andre Barbour—also has been chosen for the ENR national Top 20 Under 40 list. He will be recognized for his achievements in March at the ENR Emerging Leader’s Forum in Chicago and will be featured along with the other winners in a cover story online in May and in the May 13 print issue of ENR.

Other regional winners include Garrett Bolella, working for the city of Norwalk, Conn., who has the spark to reinvigorate critical projects and help them reach completion; Suzanne Broadbent, a senior communications director at Kennedy Jenks Consultants, who is engaging with the latest technology tools to help grow her firm’s brand; and Liam Murphy, who leads critical conversations at BR+A on sustainable design and implementation strategies for institutional clients.

Whether these winners launched their career paths in college or as far back as grade school, they all now share the determination to develop better practices and outcomes for their employers while improving the industry and the communities they serve.

Andre Barbour

Andre Barbour
36, DEI director is driving force for broad industry workforce inclusion
Diversity and Inclusion Director
NEI General Contracting
Randolph, Mass.

Barbour learned about construction from his father, who was an architect. Working on his first assignment at a 48-unit affordable rental property being developed by Boston nonprofit Nuestra CDC, he helped develop and manage walk-in applicant review procedures for project hires.

After leaving university studies in his junior year, Barbour jump-started a career in workforce development, community outreach and engagement. As a driving force now of NEI’s workforce diversity and inclusion initiatives, Barbour has spearheaded the Workforce Opportunity Resource Center in Boston’s Roxbury neighborhood to engage minority-owned subcontractors and the local workforce to promote career development and business growth within the local construction community.

The center offers workshops on résumé building, how to read construction plans and safety issues that reflect Barbour’s goal of removing systemic obstacles to work advancement in communities of color.

Barbour is involved with a host of industry groups and community-based organizations in the Boston area, including the Mayor’s Office of Returning Citizens, the Gavin Foundation, Project Turn Around and the Massachusetts Minority Contractors Association.

He is also a liaison with Madison Park Technical Vocational High School in Boston. Barbour also was selected to be one of this year’s ENR national Top 20 Under 40 winners.


Garrett Bolella

Garrett Bolella
36, Traffic engineer creates momentum
Assistant Director – Transportation, Mobility and Parking
City of Norwalk
Norwalk, Conn.

Bolella has both the vision to innovate new city transportation projects and the ability to rejuvenate work that needs help reaching the finish line.

In 2017, Stamford, Conn., officials hired Bolella as a lead traffic engineer for a newly created transportation bureau. Within days, he began redesigning the city road network, planning for a new road design and pavement layouts and creating Stamford’s first buffered bike lane to improve safety for cyclists.

Bolella’s most notable transportation projects in Stamford included design of the city’s first roundabout. The project was initiated in 2003 but had stalled, so Bolella used his consulting experience and leadership prowess to organize community meetings that led to finalizing the design in 2019 and securing funding through the Connecticut Dept. of Transportation.

In 2020, Bolella was elevated to assistant director for transportation mobility and parking for the city of Norwalk. As in Stamford, he rejuvenated the city center that had never fully recovered from a 1955 flood. Following 35 years of planning without results, the engineer led the design for a $27-million revitalization project and secured grant money to enable its completion.

Among his volunteer activities, Bolella works with a University of Connecticut student group every year on real-life projects throughout their entire senior year related to their class on engineering and design.

At 26, she pitched, then posted the first social media posts for the Arcadis U.S. operating company, heralding the era of content marketing for the firm.

She later joined Golder Associates as director of internal communications, the youngest person on the firm’s U.S. leadership team. After the firm was acquired by WSP in 2021, she assisted with its integration into the larger firm.

Broadbent joined Kennedy Jenks in 2022 and established in-house communications and improved digital assets, always looking for ways to leverage technology for smarter communications delivery. Since being named principal in 2023, she has been leading the launch of a national webinar program and is guiding the firm’s updates of its digital assets to foster growth and refresh its digital brand.

Committed to diversity, equity and inclusion in the workplace, Broadbent recently completed the eCornell diversity and inclusion program held by the Cornell University School of Industrial and Labor Relations.

Parkinson has amassed a wealth of experience on a range of large and complex projects in his 18 years in the construction industry, Suffolk says.

Working on the renovation to transform Boston’s Charles St. jail into the Liberty Hotel—while involved in the contractor’s co-op program—solidified his passion for construction.

Since then, Parkinson has expanded his knowledge through work on some of Suffolk’s most challenging projects. He was superintendent for Encore Boston Harbor, a 3.2-million-sq-ft resort that was completed in 34 months, and on Boston’s 1.1-million-sq-ft., 60-story Millennium Tower, the city’s third-tallest building at the time of its completion in 2016.

As senior superintendent on Suffolk’s 62-story, 1.8-million-sq-ft Winthrop Center, Parkinson directly managed a team of 10. The center's tower, completed in August, is Boston’s second-largest vertical development and the largest Passive House building in the world.

Parkinson is also actively involved as a mentor at Suffolk. He serves on the contractor’s national safety committee and joins with firm leaders to develop curriculum for an 18-month accelerated superintendent training program.

Dedicated to community outreach, Parkinson’s team partners with Building Pathways, a Boston nonprofit aimed at providing a pathway into the construction field for low-income area residents. He also volunteers for Build It, a local carpentry pre-apprenticeship program for women. He also spends some Saturdays giving project site tours to students at Madison Park Technical Vocational High School, Boston’s only vocational high school.
