Charlie Willner Architectural Designer

I have always been passionate about building, designing, and problem solving. Before coming to architecture I studied mechanical engineering and worked for years as a carpenter. Those experiences continue to inform my work and thinking on a daily basis. I love working to solve a client’s needs in ways that also respond to the social and environmental challenges that face our community, and feel lucky to have joined a team that approaches design in a creative and collaborative manner.

Jeff Stetter, AIA Architect

From the earliest age, building and design have been a part of my life. My father was a carpenter contractor and my three brothers together continue the business he started in 1958. I loved the Baker Hunt Foundation art classes that I took growing up in Kentucky. Architecture seemed like the perfect synthesis between art and construction. The days I spent working with my father and brothers over 20 years ago still influence me today.

Design has always been the governing focus of this firm. I feel extremely lucky to work with a group of such talented and committed people. We tend to feed off each other's enthusiasm and a cross pollination of ideas creates designs that we are all proud of. Working on a project from conception through warranty walk through especially excites me. Design happens not just at the big idea stage, but at every decision along the way. It’s the sum of those decisions that makes great Architecture. I’ve been working at GBA since 1994 and have enjoyed every moment.

Jessica Thyme, AIA, LEED BD+C AP Architect

Montpelier has been my home for over 5 years and working with the gbA team has been a great introduction to the community, each one is involved in ever-changing roles and services. We often live close enough to regularly see our projects and I enjoy working with the GBA team on enriching our surroundings with the enduring art of architecture. I am always seeking to improve the impacts of our buildings on the environment, our cultural, and the people who inhabit and build them.

Jessica Gardner Architectural Designer

My interest in architecture and construction began when I was a kid working on renovating my family’s house in Western Massachusetts. My father also worked at Lego, so there was a never-ending supply of bricks to build and design with. That interest grew into a career in architecture. I enjoy solving design problems and continuing to learn about architecture and construction.

He believes architecture is a vehicle to connect people and place, and has enjoyed designing affordable housing projects, schools, libraries and community resources across New England for over thirty years.
