Narrowing down the number of candidates for inclusion in ENR MidAtlantic’s class of 2023 Top Young Professionals to just 20 winners was a difficult assignment for our industry judges given that this year there were more than 60 nominees. To determine the winners, the judges considered each candidate’s contribution to the industry and their contributions to their colleagues and community.
We strongly encourage anyone who applied but did not win to resubmit next year if the candidate is still eligible. Be sure to save a copy of your entry and add in the applicant’s most recent accomplishments.
ENR thanks the industry judges who undertook the selection challenge, diligently reviewing entries to choose the 20 winners for this year. The judges were: Elizabeth Brownell, senior associate at Thornton Tomasetti, and a member of ENR’s 2021 national Top 20 Under 40 group, and Chris Fletcher, project director at McCarthy Building Cos., and a member of ENR’s 2022 national class.
Congratulations to the three regional winners who were chosen this year to be part of the national Top 20 Under 40 cohort: Tauhira Ali, executive director of industry innovation at the National Electrical Contractors Association; Margaret Hopkins, vice president at AKRF Inc.; and Stephen Parker, behavioral health planner at Stantec.
ENR will recognize the national-level awardees at the Top Young Professionals Conference set for March 8-10 in New Orleans. The event is a great opportunity for all industry professionals to learn more about construction sector challenges and gain insights on career development. It will include expert presenters, panel discussions and focused workshops on critical industry topics, plus many opportunities for networking with peers, management, clients and specialists.

Using positive energy to build high-performing teams
Clark Construction Group
Bethesda, Md.
Whether in a combat zone or on a construction site, leadership is critical for completing a mission as efficiently and safely as possible. Small wonder then that Conner Gentil’s nearly decade-long stint as a U.S. Marine Corps infantry officer has been instrumental in his ability to guide complex projects. Beginning with the transformation of a circa-1922 building near the National Mall into the Museum of the Bible, Gentil has since tackled challenges such as the 11.5-mile extension of the D.C.-area Metrorail Silver Line to Dulles Airport and Project Speedway, Amazon’s 2.7-million-sq-ft fulfillment center in Richmond.
Gentil’s military experiences provide him with a perspective that helps his team treat an occasional project setback as a problem that can be solved rather than a desperate crisis. Gentil also strives to balance his fast-paced career with the demands of a growing family and a strong desire to give back to his local community. An Eagle Scout during his youth, Gentil is passionate about conservation efforts and regularly seeks out service projects that support wildlife and the ecosystem.

Heather Riebeling
Heather Riebeling
37, Project Manager
Making a difference in a key engineering specialty
Heather Riebeling was only two years out of college when she was asked to join AECOM’s three-member overhead contact systems (OCS) team, formed to fill Amtrak’s need for minor regrading of catenary in the vicinity of bridges and other tasks in the field of OCS design.
Always looking to expand her knowledge base, Riebeling jumped at the chance to become involved in a specialty field that consisted of fewer than 100 engineers in the U.S. Quickly excelling in the niche practice of transit rail systems and focused on client support, she helped transform the OCS group into a 17-person multidisciplinary team that works on projects across North America.
Riebeling has put her communication and leadership skills to work to benefit professional organizations and the communities they serve. In addition to serving on the IEEE Vehicular Technology Society’s OCS committee, she blends her advocacy and musicianship as a trumpet player and board member with the Philadelphia Freedom Band, a 501(c)3 organization that is part of the Pride Bands Alliance.
