People-Centered Firm
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.
