Three years after the passing of founder Mark Humphreys—and as it settles into new headquarters—Humphreys & Partners Architects is entering a new era while doubling down on its roots.

The Dallas-based firm, known internationally for rethinking how multifamily housing gets built and visionary concepts like the “Uber Elevate Mega Skyport,” has announced a new leadership team and operational shift meant to carry it into the next three decades.

Humphreys’ signature design playbook has long focused on packing more density into livable spaces—often borrowing cues from single-family neighborhoods. Its patented Big House model mimics the look of a large, single-family home while containing multiple apartment units. Other concepts, like the compact e-Staks series and the parking-concealing MotorCove, prize density with pedestrian-friendly, street-level design.

The firm’s “generational transition” includes five leadership moves across architecture, interiors, operations, and culture.

The firm also moved into a new headquarters in July, relocating to 6111 W. Plano Parkway, Suite 1800. The space was designed to fuel collaboration and ideas, marking a physical and symbolic step forward, the company said in a recent LinkedIn post.

A design-led transition

Robin Bellerby, AIA, has been named chief architecture officer. She steps into the role after more than 30 years in multifamily design and leadership, much of it with Humphreys.

“This is a firm built on design,” Bellerby said. “We’re doubling down on a foundation over three decades strong. Clients come to us for thoughtful, buildable, market-savvy solutions—and now, we’re even more focused on strengthening that mission.”

Previously senior vice president of strategy & risk, Bellerby has helped guide the firm’s alignment of design with business performance and the evolving demands of development.

A lifestyle-first interiors approach

On the interiors side, Chelsea Dora-Shibley has been named chief interior design officer, while continuing as president of HPA Design Group. Under her leadership, HPA’s interiors arm has grown into a multifamily design leader known for its elevated, resident-focused approach.

“Our interiors work is about more than just finishes—it’s about creating spaces people want to spend their lives within,” Dora-Shibley said. “Whether we’re collaborating with our own architecture team or with external partners, we bring the same attention to lifestyle, function, and design integrity.”

Carrying the vision forward

The leadership shift also marks a transition for longtime president Greg Faulkner, AIA, who now serves as president emeritus. Faulkner helped lead the firm through decades of expansion and will continue to advise on growth and client strategy.

“My goal with Mark was to build a firm that clients could count on and that our teams could be proud of,” Faulkner said. “We built a hell of a firm, and I trust this new leadership to keep that fire lit and take it even further.”

A focus on people and performance

Brad Tillett, who joined HPA as CFO last year, has been elevated to chief operating officer, now overseeing firmwide operations and financial strategy. He’s joined by Erica Brodie, newly appointed vice president of HR and Workplace, who is tasked with strengthening internal culture and the employee experience.

“Culture isn’t just about perks—it’s about trust, communication, and clarity of purpose,” Brodie said. “We’re building an environment where people feel supported, connected, and proud of the work they’re doing. When that happens, everything else—the creativity, the collaboration, the results—gets stronger.”

For Tillett, the path forward is about giving teams what they need to deliver at the highest level.

“In a short time, I’ve seen just how much this team cares about doing great work—and doing it the right way,” he said. “There’s momentum here, and I’m excited about where we’re headed.”
