Meet Our Engineers
Our team of licensed professional engineers brings decades of combined experience in civil engineering and land development across the Southeast. Every client works directly with a PE.
Barret started his career in the construction industry working in the family plumbing business in Florida — a formative experience that instilled a strong work ethic and an understanding that success is generated by hard work. After college, he worked in Atlanta for Haines Gipson and Associates during the booming retail development era of the early 2000s, then spent 2003 to 2010 with two Triad-area firms — an engineering design firm and a design/construction management firm. Observing firsthand how designs translate into actual construction gave him a practical perspective that other engineers rarely acquire, and ultimately led to the founding of Hagen Engineering in 2010.
Barret has relocated to Knoxville, Tennessee, where he leads Hagen Engineering's Tennessee operations — working directly with developers and municipalities throughout East Tennessee while staying involved in every project to ensure clients receive the best work product the firm can provide across all eight licensed states.
Tim grew up in Charlottesville, Virginia and studied civil engineering at Virginia Tech, focusing on Land Development Design and Water Resources with a minor in Green Engineering. He gained extensive field experience through a project management internship with Trident Construction, helping oversee construction of a 7-story Residence Inn Hotel. Since joining Hagen Engineering, Tim has obtained his PE license in five states and worked with municipalities of all sizes across the Southeast. As VP of Operations, he brings an innovative yet practical approach that ensures cost-effective final results for each client.
Nolan grew up in Winchester, Virginia and earned his civil engineering degree from Virginia Tech, graduating in 2016 with a focus in Land Development and a broader emphasis on Hydrology and GIS. Joining Hagen Engineering straight out of school, he has gained deep experience in all aspects of design — visiting sites to observe how designs translate into actual construction and managing multiple projects simultaneously. Nolan works closely with clients to produce work that is practical, cost-efficient, and aesthetically pleasing — a personal approach that keeps clients coming back.
Bryce grew up in Franklin County, Virginia and earned his civil engineering degree from Virginia Tech with a minor in Green Engineering — a combination that showed him how projects can reduce environmental impacts and lower costs at the same time. After interning with a civil engineering firm's Land Development group during college, he joined Hagen Engineering, where he has earned his PE license and continues to expand his land development expertise — delivering quality work that meets every client's needs with prompt, friendly service.
Jared grew up in Greenville, North Carolina as a lifelong NC State fan, which led him to NC State's engineering program and a focus in land development. Since joining Hagen Engineering after graduating in 2020, he has gained experience across all aspects of design — visiting sites to observe how designs become finished construction and managing multiple projects simultaneously. Jared is confident that working closely with clients always produces practical, cost-effective results.
Charlie grew up in a military household — living in North Carolina, Florida, and Germany for over a decade — before earning his civil engineering degree from the University of Central Florida with a specialization in Stormwater Management. His senior design project took a development from inception to close-out with a ten-student team. Charlie understands that every project brings its own challenges, and his background across multiple cultures has made him flexible and quick to adapt to each project's circumstances.
Matt grew up in Kernersville, North Carolina and pursued civil engineering at UNC Charlotte, where an internship with Hagen Engineering sparked his interest in land development. As an intern he led preliminary layouts and design concepts for single-family and multi-family projects, then accepted a full-time position with the firm. Matt's commitment to excellence drives him to produce high-quality, aesthetically pleasing work while maintaining respectful, collaborative relationships with clients and colleagues.
Esteban grew up in Seneca, South Carolina and earned his civil engineering degree from Liberty University. While in school he worked as a Field Engineer, gaining hands-on experience in construction layout and field stakeouts using Trimble technology while coordinating with subcontractors to ensure accurate execution of plan sets. With strong communication skills, bilingual fluency in English and Spanish, and a detail-oriented mindset, Esteban is committed to high-quality work and continual growth as a civil engineering professional.
