Justin Mendinsky Named Assistant Vice President of Water/Wastewater Services
We’re please to announce that Justin Mendinsky has been promoted to assistant vice president, overseeing the firm’s water & wastewater service group. The position was created as part of an ongoing organizational realignment to scale the firm for growth while preserving its commitment to technical excellence and personalized service. The realignment creates unique channels for client outreach, technical expertise, and operational delivery, ensuring each gets proper focus and attention.
Justin’s position is part of the channel focused on technical expertise. As such, he will be responsible for driving quality and consistency in project delivery across the organization by ensuring best practices are implemented across all water and wastewater teams and ensuring staff members get the training they need to meet evolving industry standards. He will also foster a collaborative, results-driven culture in the water and wastewater division.
Justin previously managed the water & wastewater team in HRG’s Harrisburg office and has more than 20 years of experience with the firm. He is active in the water and wastewater industry, serving in various leadership roles with the Central Pennsylvania Water Quality Association and Pennsylvania Water Environment Association over the years. In addition, he serves the community as a member of Carlisle High School’s Occupational Advisory Committee, ensuring engineering coursework reflects the skills students need to join the workforce and sharing work experience with the students in the classroom.
Mentorship is a key aspect of the assistant vice president position, according to Erin Threet, HRG’s vice president of services, and Justin excels in that role. She says, “Justin has been a mentor and friend to me since my first day at HRG, providing an impressive knowledge of how to bring projects to fruition. This includes some of HRG’s most complex and innovative projects over the past 20 years. He is quick to help any member of the team and works harder than almost anyone I know. I can’t imagine anyone better to lead and inspire the water and wastewater team.”

Adrienne Vicari is being promoted to vice president of growth, a new position that drives new client development across the organization.
“To achieve our growth goals, we need to anticipate and offer the services our clients will need most in the coming years. Yet, even as we expand our service offerings, we must continue to deliver our services with the same quality, creativity, and attention to detail that our clients have always relied on,” Chief Operations Officer Ed Ellinger says. “Our technical service experts will determine what services we offer and the quality standards for delivery. Jim will work with the operations leaders in each office to build capacity for those service offerings at the local level so that we can deliver projects to our high-quality standards while maximizing efficiency and operational excellence.”
Feath has managed operations for HRG’s Pittsburgh office since 2018 and has more than 25 years of experience with the firm. He began his tenure with HRG as an intern shortly after the Pittsburgh office opened and has played a key role in its growth over the past two decades. During that time, he amassed experience as a designer and project manager before taking a leadership role in regional operations. He is a registered landscape architect with vast expertise in site planning and development, particularly in the areas of parks and recreational facilities, trails, and public spaces. He is active in the industry as a member of the American Society of Landscape Architects and Pennsylvania Recreation & Park Society, but he is also actively engaged in the local community in Pittsburgh as a board member with the Butler County Chamber of Commerce and a member of the Cranberry Township Environmental Advisory Committee. His vast experience with HRG and knowledge of regional operations make him ideally suited for this role as vice president of operations.
HRG has promoted Cory Salmon to assistant vice president. Cory previously served as a group manager overseeing the water and wastewater division in southeastern Pennsylvania. He will now oversee all operations in Southeastern Pennsylvania, managing the firm’s King of Prussia office, its financial resources, and the supervision of local staff. He will also support key client management activities in the region.
HRG has promoted George White to assistant vice president. White will oversee all technical and project delivery operations in the firm’s Lehigh Valley office on Glenlivet Drive in Allentown. He will also support business development and key client management activities in this region.
Matt Bonanno has been named an assistant vice president of HRG, an infrastructure consulting firm operating in Pennsylvania, West Virginia, and Ohio. He will oversee all activities related to project delivery, business development, and general operations in the Harrisburg market beginning January 1, 2024.
Ellinger most recently served as assistant vice president, directing daily operations, project delivery, and business development throughout Central Pennsylvania. His new position as Chief Operations Officer expands his influence across the entire organizational footprint, driving productivity, quality, and project delivery through accountability metrics and implementation of operational policies, practices, and standards for all offices and service groups. He is well-known and trusted by HRG’s clients and his colleagues for his technical skill and business leadership. He first joined the firm in 2001 as a project manager in the water and wastewater service group, steadily increasing his responsibility and ultimately managing the group as practice area leader for six years before he moved into his operational role as assistant vice president. He was succeeded as practice area leader by Fox, who will now establish a new role at HRG as the firm’s first Chief Services Officer.
Fox has been serving HRG’s water and wastewater utility clients since 2006. Like Ellinger, he earned increasing responsibility as a project manager, then group manager and practice area leader managing project delivery and business development for water and wastewater projects throughout the Mid-Atlantic region. He is known for his deep commitment to his clients, his team members, and the community. He is an active member of organizations like the American Public Works Association, the Pennsylvania Water Environment Association, and the Pennsylvania American Water Works Association (PA AWWA) and has recently retired from the Pennsylvania Army National Guard. As Chief Services Officer, Fox will drive new business opportunities, expansion into new markets, and diversification of the firm’s service portfolio.
