David Koschak Architectural Designer
I came to architecture with a desire to help create healthy communities and places to live. I feel we are lucky to live within a community which recognizes the importance sustainability and beauty have in our lives, both in our towns and our rural landscapes. Working at GBA, it is rewarding to be involved in projects which are not only environmentally responsible, but which also benefit their community by creating nurturing places to live, added amenities, or beautiful places to enjoy.
I received my undergraduate degree at Wilkes University in Pennsylvania and a Masters of Architecture from the University of Oregon.
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. Its the sum of those decisions that makes great Architecture. Ive 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 Tom, Gregg, and Jeff 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.
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.
