TBG Taps Master Naturalist to Lead a New Era of Ecological Design

DALLAS, TX – July 14, 2026 – In a move that speaks volumes about the future of urban and environmental design, landscape architecture firm TBG Partners has appointed Brian Halsell as a principal in its Dallas studio. While a principal-level hire at a firm with over 130 professionals is noteworthy, the real story lies in Halsell’s unique credentials. He is not just a landscape architect with over two decades of experience; he is also a certified Texas Master Naturalist, embodying a fusion of design acumen and deep ecological stewardship that is rapidly becoming a critical asset in development.

This isn't merely a personnel announcement; it's a strategic maneuver that signals a maturation of the industry. The hiring of an expert whose portfolio is anchored in Texas’s most ecologically complex environments suggests that resilience, conservation, and authentic placemaking are no longer fringe benefits but core components of the modern development calculus. TBG's decision to bring Halsell into its leadership team is a clear investment in a future where the line between the built and natural worlds is not just blurred, but intelligently and purposefully integrated.

The Designer-Ecologist

To understand the significance of this hire, one must first understand what it means to be a Texas Master Naturalist. Established in 1997 by the Texas Parks and Wildlife Department and Texas A&M AgriLife Extension Service, the program is not a casual hobby. It cultivates a corps of highly-trained volunteers who provide invaluable expertise in managing the state’s natural resources. To date, the program's over 17,000 volunteers have contributed more than 7.5 million hours of service, with an estimated economic impact exceeding $170 million. They are the on-the-ground experts in Texas's diverse ecosystems.

Halsell brings this rigorous scientific and conservationist mindset directly into the design studio. His past projects serve as powerful case studies. At Galveston Island State Park, he helped lead the master planning for its redevelopment after the devastation of Hurricane Ike. The plan was a masterclass in climate-resilient design, incorporating 50-year sea-level rise projections, reducing impermeable surfaces by 25%, and strategically mitigating habitat fragmentation on the fragile barrier island.

Similarly, his work on Palo Pinto Mountains State Park, the first new state park in North Texas in a quarter-century, showcases a philosophy of strategic preservation. By concentrating amenities in a “heavy front-country development,” the design leaves the vast majority of the park’s 4,871 acres in a more natural, lightly-touched state for hiking, camping, and stargazing. His contributions to the Devils River State Natural Area—an International Dark Sky Sanctuary known for its pristine water—further underscore a commitment to education and preservation, with plans for a visitor center that mandates educational sessions for public access.

“Brian brings a rare combination of design vision and technical mastery to the TBG team,” said Seth Atwell, Dallas Managing Principal, in the company’s announcement. This mastery is not just in aesthetics, but in the science of creating landscapes that thrive.

A Strategic Play for a Greener Texas

The decision to bring Halsell on board is a calculated business move by TBG Partners. As an employee-owned firm with a nearly 40-year history, TBG has a vested interest in long-term, sustainable growth. In a state like Texas, which faces immense pressures from rapid urbanization, water scarcity, and extreme weather, ecological expertise is no longer a niche specialty but a critical market differentiator.

TBG Partners President Bill Odle framed the hire as a direct extension of the firm's mission. “Welcoming Brian to our team strengthens TBG's ability to take on the most complex, ecologically significant projects throughout Texas and beyond,” he stated. This move positions the firm to meet the growing demand from public, private, and P3 clients who now recognize that resilient, ecologically-sound design is essential for project viability and long-term value.

By integrating a Master Naturalist at the principal level, TBG is better equipped to navigate complex regulatory environments, source native materials, and design landscapes that provide tangible ecosystem services, such as stormwater management and biodiversity support. Halsell himself cited TBG's “reputation for design leadership and investment in people, supported by high-level technical expertise,” as key reasons for joining, indicating a synergy between his approach and the firm's strategic direction.

Beyond the Blueprints: Community and Connection

Halsell’s influence extends beyond large-scale state parks and into the fabric of local communities. His philosophy is one of active engagement, reflected in his pro bono design contributions to the Dogwood Canyon Audubon Center and a butterfly garden at the Trinity River Audubon Center. This work, coupled with his local advocacy through Friends of Oak Cliff Parks, demonstrates a belief that well-designed spaces should also be well-loved and community-supported.

This approach aligns with a broader cultural shift in urbanism. The most successful modern places are not just green, but also socially vibrant. They are platforms for education, recreation, and community building. By leading native plant walks and coordinating invasive species removal, Halsell practices a form of placemaking that empowers residents to become stewards of their own environment.

As he integrates into TBG’s work on civic spaces and mixed-use developments, this community-first mindset will be invaluable. It represents a shift from designing for a community to designing with one, creating public realms that are ecologically rich, aesthetically compelling, and deeply connected to the people they serve. This hire is a clear indicator that for leading firms, honoring the land and enriching lives are becoming one and the same mission.
