Mark leads the Momentum team, helping employees take a people-centric approach to their project work while supporting the firm’s core values of humility, drive, and fun. In doing so, Mark works closely with the firm’s partners in developing building strategies that help their organizations thrive.

"We are engaging with our partners with their best interest in mind, in a way where really, truly, the success of one of our projects is measured in terms of how successful the outcome is for our client.”

Many of Momentum’s projects are outside of the Northwest. Mark has leveraged this to cultivate a strong network of industry relationships and a client base with diversity on all levels. He believes this broad source of learning honed through diverse perspectives has led to better building strategies for Momentum’s partners, and it’s what he finds most rewarding about his work.

Mark has been working in construction management and building strategy for 16 years and holds both a bachelor’s and master’s degree from the University of Washington.

As a Senior Project Manager on Momentum’s Preconstruction team, Patrick brings experience across both preconstruction and project management, giving him a clear understanding of how decisions made at the outset shape cost, schedule and execution.

Drawn to construction by the combination of building, problem-solving and teamwork, Patrick values the opportunity to help clients turn an initial idea into a practical path forward.

“Design-build gets everyone at the table early. When the owner, designer and construction team can evaluate decisions together as the project develops, you get better communication, fewer surprises and ultimately a stronger project for the client.”

His past as a professional freestyle mogul skier shaped the preparation, discipline and composure under pressure he applies to his role at Momentum. He likes digging into the details, anticipating challenges and finding the best solution rather than simply accepting the first one.

“What stands out about design-build is the ability to collaborate directly with the design team. Instead of jumping through hoops to get one answer, everyone works together to solve problems faster and move the project forward.”

Steven is known for his service-oriented mindset and values the face-to-face relationships that are built throughout the construction process. Guided by his faith in both his work and daily life, he prioritizes communication, trust, and maintaining strong connections with clients and teammates alike.

Outside of work, Steven is a family man, enjoying life with his wife and two young children.

A natural curiosity about how things come together inspires Mason's work as a Project Engineer.

Seven years into his career, with a degree in Construction Management from Eastern Washington University, that same curiosity still drives the way he approaches every project.  

"My favorite part of the job is collaborating with clients to figure out exactly what they want- and then making that happen. Every region has its own personality, and I really enjoy getting to know the people and the place behind a project and seeing how that regional flair comes through in the building's design."

Outside of work, Mason has a passion for the outdoors and enjoys cooking authentic dishes from around the word. He lives in West Seattle with his dog, Luna.

David brings close to a decade of commercial construction experience to his role as project manager at Momentum — work that has spanned large-scale multi-family development and office construction across the greater Seattle area. 

 David was drawn to the built environment early and has built his career around it. He thrives on the collaborative side of construction: working across internal and external teams to move a project from conception to completion, and solving the hard problems that come up along the way.

On design-build, David puts it simply:

"Design-build is more collaborative and gives you more ownership of the project and outcome — and ultimately delivers a project the client can be happy with."

Constant communication and transparency are how he makes that happen on every job.

Outside of work, David skis, plays tennis, boxes, and spends time with his cats

Ronny has spent more than 30 years in commercial work, the last 13 of them as a construction superintendent.

He came to the superintendent role after two decades in commercial audio visual, and the switch put him where he'd always wanted to be: in the field, watching a site progress from demo to final clean.  For Ronny, the advantage of design-build is clear:

"To know that the client and the designer have already been through a complete creative process — that the client's vision of their new space is being expressed by the designer onto blueprints and renderings — really makes the final product more satisfying to the customer."

That's what design-build means to Ronny, and it shapes how he runs a job. Years of different builds, different situations, and different customers inform the decisions he makes on site every day, all pointed at the same finish: a completed project and a client who loves their new facility.

Off the clock, Ronny builds and shows custom trucks, mountain bikes, and spends time with his kids, grandkids, nieces and nephews. His favorite pastime is a good old road trip — getting out and seeing America.

Larry is one of our superintendents on the ground in Knoxville, managing project sites and subcontractors and making sure the work gets done right and on schedule. With 30 years in construction, he brings the kind of experience that recognizes problems before they arise.

Larry's strength is in the details – he's good with numbers, has a sharp memory for the specifics of a job, and finds genuine satisfaction in watching a building come together from the ground up.

"Design-build means the architect and builder are coordinated from the start - and that generally means faster answers and fewer surprises on the job site.”

Outside of work, you'll find Larry out on the water fishing or boating, and spending time with his family over good food and a drink poolside or at the beach.

Tim brings 11 years of experience as a superintendent to his role at Momentum. He spent most of that time on retail tenant improvement projects.

On every job, his focus is on completing the project and keeping it moving toward the finish line.

His greatest strength is working collaboratively with other people. He values the teamwork it takes to bring a project together and sees himself as a steady partner to everyone involved, from the project team to the client.

Paul is a construction superintendent at Momentum, where he brings more than 30 years of commercial construction to his role, including ground-up builds and remodels of existing facilities, on projects across the country.

His love of planning, creating and building things drew him to the field, and three decades in he still measures a job by how well everyone on it does — the contractors succeeding at their work, and the client moving into a space they love and that they had a hand in shaping.

Design-build keeps collaboration open longer than a traditional build does, and Paul sees the value of it for the client:

"I appreciate the flexibility in helping a client work through their needs and desires in creating a fresh new work environment."

Outside of work, Paul is outdoors as often as he can be — canoeing, fishing and bike riding — and he makes a point of seeing what's worth seeing in the towns his projects take him to.
