Jim Parker, Jr., PE, PLS

Principal and Chairman of the Board

Jim is a true entrepreneur. When he sees an opportunity, he goes after it and never looks back.

Jim is proud of the close-knit team environment he has cultivated by encouraging his employees to grow and seeing his clients succeed. Behind Jim’s leadership and experience, Summit has grown exponentially, expanding into new markets and becoming a well-known firm in the southeast.

"The Visionary"

Troy Dover, PE

CEO & President

It’s said that Troy has never met a stranger, and this sentiment rings true. That’s because Troy is not your typical engineer. Sure, he enjoys all of the things that engineers are known for—crunching numbers, pivot tables, solving problems—but he’s also a real man of the people. He's got a reputation for checking in with employees around the office daily, ensuring they’re all happy and thriving. Even after doing his rounds to make sure everyone has what they need to succeed, Troy still manages to find time to keep Summit moving forward by identifying new and exciting opportunities for the firm. Although we all roll our eyes when he says “we’re building dreams here,” we know he has everyone’s best interests in mind with every decision he makes.

"The Catalyst"

Scott Ashton, CPA

Chief Financial Officer & Treasurer

Scott has always been a self-proclaimed bean counter. He’s been working as our CPA since Summit began, but now, he flies our colors and leads our crew of financial experts. Scott manages to find the calm in any storm—after all, being both trustworthy and capable has let him sail through over 40 years in finance. A perfect weekend for Scott would be spent kicking back on a boat while fishing for marlin or mahi-mahi, enjoying a cheeseburger in paradise, or participating in some competitive barbeque. During the week, you can find Scott settled in at our corporate headquarters, keeping an eye on the skies and helping guide our success.

"The Captain"

Rick Leone

Senior Vice President

Rick started with Summit in 2018 and played in a golf tournament on his second day. That’s not to say that he isn’t a hard worker, though—Rick is doing about 200 different things at any given time, mainly focusing on growing our company’s reach. He is no stranger to the industry, either, with over 25 years of experience in the environmental and engineering consulting world. Rick was one of several employees recruited by Jim Parker after they had several run-ins in downtown Hillsborough. What Rick enjoys most about working for Summit is doing what he loves every day (and getting a little work in, too).

"The Golfer"

Ginny Kirk Andrews

Vice President, Communications & Marketing

When Ginny Kirk joined our team, she brought her talents in communication, community relations, and speaking loudly with her. She manages the workflow of the marketing department, which is integral to winning work for our firm. She also leads community relations efforts and organizes our entire organization's internal and external communication. Her favorite part about working here is that she is encouraged to command a room with her outgoing personality.

"The Voice"

Shane Parker, PE

Vice President, Design Services

Shane has worn many hats in his career. From Asset Manager to Chief Estimator and everything in between, he’s had his fair share of roles. Budgeting, bidding, working on proposals: if it’s related to operations management, he’s had a hand in it in the past. At Summit alone, he’s worked in Construction Materials Testing, Surveying, and Maintenance Management before stepping into his role as Director of Operations. Outside of work, he’s a steadfast and stable guy with down-to-earth interests and no fear of speaking his mind. A perfect day for Shane involves spending time with his kids at the beach, mowing the lawn, and fixing up projects around the house—the picture of a reliable family man.

"Mr. Reliable"

Ben Wallus, PE

Vice President, Construction Services

Ben has been working in transportation construction since 2009 and has the expertise to show for it. He’s conducted work all over the region, with a portfolio featuring projects across Tennessee, Virginia, West Virginia, and North Carolina. In fact, he’s earned his Professional Engineering license in ten different states! This makes him the perfect person for his role as Director of Operations, where he’s gotten to know many of the managers, clients, and business contacts we rely on for our work to thrive. We call Ben “The Chameleon” because he has the unique ability to blend into any role, any time, to ensure Summit’s continued success.

"The Chameleon"

Matt Bales

Vice President, Strategic Initiatives

Matt Bales has over ten years of experience in the government relations field. His career has centered around developing a plan and story, communicating it to the right audience, and shaping the outcome – basically, being the amicable chess player we all like to have on our team. He loves the sense of purpose that comes with his job and enjoys being surrounded by people equally as passionate about positive change as he is. When he’s not discussing strategy or collaborating with our leaders on crafting the future, you can find Matt relaxing on the Cascades Trail off the Blue Ridge Parkway with his family or practicing his fly-fishing skills.

"The Chess Player"

Nute Thompson, JD

Vice President, General Counsel & Secretary

A graduate of the University of North Carolina's School of Law, Nute brings Summit a fresh and modern perspective on legal consultation. He's got his eye on the intersection between business and legislation, which makes him instrumental to Summit's ongoing business development strategy. His history of advocacy makes him a force for positive change at Summit, which is how he earned his nickname. When he's not busy tackling the legal nuances of Summit's day-to-day operation, you can find Nute on the golf course or exploring the great outdoors. As a native North Carolinian, Nute has visited every county in the state, hiking and exploring alongside his four-legged companions. With Nute on our side, we know we're in good hands!

"The Advocate"

Zack Weddle, PE, CCM

Chief Engineer

It’s hardly a mystery why Zack is our current Chief Engineer. With a background in construction engineering, transportation engineering, traffic engineering, and land development, Zack has over 39 years of civil engineering experience within the industry. Before his current role, he managed our operations in Virginia. His hard work, determination, and “charge ahead” attitude has helped us pave our way into new and emerging markets within the state. Zack is happy to be at the head of Summit’s charge because it offers him the opportunity to grow a company that he cares about, one that has great people working for it and places high value on employees and clients.

"The Pioneer"

Sue Holaday, SPHR

Chief Human Resources Officer

Sue was the firm's first full-time HR professional, and ever since that first day, she has been all about securing more talent for Summit. This is no small task—With over 400 current employees, Summit is known for both its award-winning projects and its meteoric growth! Sue stays very busy between employee orientation and career fairs, ensuring our people have the best benefits we can offer. Being a part of our continued growth and the numerous opportunities that come with it makes her excited to be part of the Summit team.

"The People Person"

Charlene Toellen

Controller

Charlene has been with Summit since its early days as Callamyn-Parker, rising from temp worker to Controller over an impressive 24 years of service. She is an incredibly versatile member of our community who has met every challenge that came her way, expanding her skills in the process. Her experience in administration, billing, property management, and maintenance has given her an in-depth understanding of the company's assets and expenses, and she manages payroll, accounts payable, company logs, balance sheets, employee expenses, and cost allocation with unmatched skill. Charlene's versatility extends beyond work, as she enjoys traveling to different parts of the world outside of North Carolina and embarking on new adventures alongside her son, husband, and four-legged friend Dusty.
