“My main objective with all projects is to add value and exceed the client’s expectation. I achieve this by combining my technical expertise with proactive management techniques, delivering comprehensive design solutions for private and public projects. My aggressive hands-on approach to management has resulted in hundreds of successful projects ranging from small in-fill sites to large-scale developments such as Santana Row.”




Greg Hurd, PE, PLS, LEED AP Vice President


“I recognize that our clients are diverse and have different consulting needs. We keep each client's ultimate project goals in mind while managing the project budget, scope, regulatory compliance issues, safety, and overall efficiency. I make every effort to meet and exceed client expectations by providing cost-effective solutions that incorporate creative planning and superior technical execution through bringing the strongest possible team to the project from both in-house and outside resources that lead to successful outcomes--the client's vision, delivered.”



Jaysen Long, PE, LEED AP

Vice President


“Relationships are key to the success of a design professional. Establishing or maintaining a long-term relationship with a client is my primary intention on each project we undertake.

Vice President


“Anticipating and identifying critical design and project constraints early in the design is instrumental to the success of a project. I feel that proactive communication, both within the design team as well as with project stakeholders, is also key to success.”




“Surveying is my passion. I began my surveying career in high school, working as a chainman on a field crew. It’s an amazing process to be a part of living history for future generations to build great things. I share this perspective everyday with my teams - keeping them engaged to complete projects with a high degree of professionalism and to the client’s satisfaction.”


Brian Scott, PE

“Since starting my career here at BKF many years ago, I have grown both professionally and personally. As a father of 3, my approach to design is influenced by how I would like the future to look for my children. This future includes incorporating sustainable design into healthcare and educational campuses, residential and commercial developments, and park and public utilities.  When designing, I try to envision how my family would feel using these facilities. My goal is to help your project become a place that many generations can enjoy.”





Jacob Nguyen, PE

I manage large design teams and work closely with public agencies, community organizations, utility companies, institutions, and private owners to incorporate specific concerns and regulations into the design."


Eric Swanson, PE, QSP/QSD



“I specialize in infill and reuse sites.  I leverage my understanding of the local site conditions, governing jurisdiction requirements, and my construction background to deliver successful projects. I especially enjoy the design-build delivery system, as I believe the collaborative process provides the best value for the project owner. Through extensive communication I am able to identify and resolve challenges efficiently for my clients."




Jason White, PE, LEED AP



"I have always enjoyed the design process and sense of achievement that results from arriving at thoughtful, sustainable solutions through collaboration with clients, stakeholders, and design team partners. With 20+ years in civil engineering managing projects throughout Northern California, I am able to provide valuable insight  from a project’s conception, entitlements, design and construction.  I lead a team of engineers proficient in supporting civic, transportation, education, and private development projects with emphasis on frequent communication and teamwork."

”Integrating sustainable design strategies with a thoughtful consideration of infrastructure requirements and site constraints is fundamental to a project’s success. My approach to project management and collaborative client and consultant relationships has a proven track record on a wide variety of land development projects, including mixed-use, commercial, residential, roadway, R&D, and campus developments. Building on my experience with sustainable infrastructure, site planning, grading, utility design, cost estimating and construction administration, I am able to effectively consult with clients to deliver results at multiple phases of the development process.”



Chuck Humpal, PE, QSD/QSP



"Civil engineering is problem solving, but the technical design is often the least demanding problem to be solved.  Understanding and addressing clients' needs and expectations, satisfying agency requirements, clearly presenting options and recommendations to facilitate team decisions, and developing a design that is constructible and cost-effective as well as technically correct - these are the aspects of the job that keep project management challenging and rewarding for me after 25+ years in the industry.  Working with a great team of professionals, including owners, management consultants, designers, contractors, and reviewers, to successfully complete a difficult project - that is what makes the job enjoyable."
