We’re a fun-loving team, that is passionate about sustainability in our work, our operations, and our communities. We treat our team, our clients, and our stakeholders as valued and critical players in our work and our impact.
Brendle Group is proud of our more than 20 year history helping clients reach their sustainability goals! We’re excited to share a little bit about our history, our purpose and mission, and our exciting team of talented professionals.
When our President, Judy Dorsey, started Brendle Group in 1996, she chose her mother’s maiden name, Brendle, as its foundation.
Eileen Brendle-Dorsey was a leading edge-architect promoting green building techniques as early as the 1950s, with plans to start her own firm one day. Eileen’s career was tragically cut short – she passed away from breast cancer in 1970, just short of her 40th birthday.
Brendle Group’s name is a tribute to all women and leaders challenging conventions and to Eileen’s vision and enduring legacy.
Brendle Group has been practicing sustainability since the company was founded in 1996, and we are committed to embodying sustainability principles in our own operations.
Apply our engineering and consulting talents to create lasting impacts that sustain and inspire our communities and our world.
Within 5 years, we will identify, lead, and catalyze with our national clients the next significant innovations in sustainability, sharing our success with an international audience and scaling our impact by making sustainability the norm in unexpected places.
- We strive for exemplary client satisfaction by understanding each client’s unique needs and offering the best solutions for the best value.
- We commit to sustainability in our own operations and serve as a test bed for emerging policies and technologies.
- We promote a healthy and sustainable local living economy in the places we work.
- We operate collaboratively rather than competitively to address the magnitude of issues our planet faces.
Sustainability is at the core of everything we do. To see how we incorporate sustainability into our operations, team dynamics, and community, check out our interactive Sustainability Management Plan here and review our annual progress here.
