    Get To Know the Team

    Heather Donahue, AIA

    Principal Architect, Partner

    Heather’s love for design began building at an early age stacking Legos and perusing house plan magazines. Her interest in architecture led to a Bachelor of Architecture degree from Texas Tech University. Having lived and practiced in Oregon, Colorado, and Uganda with her architect husband, she is a licensed architect in Colorado as well as Texas.

    With both residential and commercial design experience, Heather is committed to sustainable design with a special interest in historic sensitivity. After many years as a stay-at-home mom and contract designer/drafter, she returned to full-time employment joining MOD: in 2018 where she quickly became an integral part of the team. Heather currently lives in a three-generation household with her husband, son and mother in Round Rock, Texas where Legos can still be found in abundance.
