Founded in 2007, J2 Engineers was built to be different: A different approach to engineering services, a different employer for talented engineers, a different niche in the marketplace.

A decade later, J2 has made a big deal out of being small. Our focus remains on our clients’ goals and meeting them through excellence in engineering. We’ve cultivated an environment where mentorship, cooperation and collaboration let our people shine. Our clients know the owners, have come to expect top quality and fast service, and trust J2 to be thorough, risk-averse, and yet innovative.

J2 provides top-quality professional services span planning, zoning, engineering, transportation and surveying. Our team utilizes the latest technologies and upholds the highest professional standards in the practice of engineering and surveying.


The strength of our firm starts with our Principals, each bringing years of technical and management experience, as well as a clear vision of J2’s future. Our founders are actively involved, working side-by-side with our teams on creative, cost-effective and environmentally sensitive engineering solutions.

James C. Bishoff, P.E., Founding Principal

J2 is what giving back looks like. Early in his career, Jim received support and guidance from mentors in the industry. Those contributions were pivotal, launching a career of transportation design excellence. When he founded J2, Jim vowed to create a collaborative environment where employees receive the same kind of support from more experienced engineers, developing a sense of ownership in the work and the firm. A graduate of West Virginia Institute of Technology, Jim worked for VDOT and with other industry-leading transportation firms before founding J2 Engineers. He’s a golf enthusiast and involved with his daughter’s volleyball activities.

Jeffrey L. Gilliland, P.E., Founding Principal

Jeff founded J2 Engineers with Jim after the two met and worked together at another firm. He sees his role as a navigator, guiding the ship to reach client goals. By focusing on the end game, Jeff has helped build client trust, freeing them from micromanaging and steering away from obstacles. His perspective was honed over nearly 30 years of land development experience with private developers, public corporations and public agencies. A graduate of Virginia Tech, Jeff has lived and worked in Virginia for his whole life, with kids who are continuing the legacy as Hokies. Jeff is a marathon runner whose passion has inspired others to run.

Robert W. Brown, PE, Principal

Bringing a vision to reality is Bob’s favorite part of engineering. He enjoys the design process that starts with an idea and ends with a plan. Bob brings years of design and construction experience to J2, helping the firm reduce risk and save time and money for clients. He enjoys a good challenge and the diversity of skills needed for J2’s on-call contracts. In fact, Bob’s attitude drives the firm toward sustainable growth that keeps pace with an evolving civil engineering market. Bob is a baseball guy at heart, but he also plays dodgeball on J2’s team.

Gustavo brings large scale land development and civil engineering experience to J2 Engineers. He takes great pride in mentoring junior staff and heads up our Land Development group in the Leesburg office. Gustavo was originally interested in architecture, but changed tracks to engineering after interning at an engineering firm and being exposed to the wide range of disciplines that engineering offers.  Gustavo enjoys the client and project diversity at J2, as well as getting to work directly with clients on projects.  In his free time, Gustavo enjoys spending time with his family, running, and swimming.

Eric Erickson, LS, Associate

With more than 30 years of surveying experience, Eric often feels like he’s seen it all. But it hasn’t curbed his enthusiasm for a new project. As the first in and last out, Eric knows that everything is built upon the surveying work so details count. He’s a big proponent for combining new technology with old school experience. Eric is a lifelong resident of Clark County and appreciates the relationships J2 has in Northern Virginia and the impact J2’s work has in developing projects and new land use. Eric’s downtime is spent with a fishing pole in hand.

Sebastian Sandoval, PE, Associate

Sebastian heads J2’s recently-opened Prince William County office.  He credits his uncle for setting him on the path to becoming an engineer.  His uncle was an architect and Sebastian remembers visiting him as a child and being fascinated with the plans and models that his uncle created.  Starting his studies in architecture, he found himself becoming more interested in roads and civil related studies, so he made the switch to civil engineering, and graduated from George Mason University.  What Sebastian enjoys most about civil engineering and working at J2 is seeing the final product where all the work from different places come together.  In his free time, Sebastian enjoys spending time with his family, watching movies and working out.

Jonathan Wilfong, PE, Associate

Enjoying the variety of projects he has been introduced to through his career, Jon believes those projects benefited from the team environment he embraces.  He was raised with a strong work ethic that he learned from his parents which has prepared him to produce high quality work and ensure client satisfaction.  Jon relishes mentoring junior engineers to ensure they start their career in the right direction and has become the office “go-to guy” to help the other engineers when they have a question or problem on their projects.  A graduate of West Virginia University Institute of Technology and resident of Loudoun County, Jon enjoys family activities, coaching and sports in general.
