About the firm

Creating an optimal building experience

O'Hara & Gercke was established in 2002 by Kevin O'Hara and James Gercke to focus on residential construction. In 2022, Zach Mitchell joined as a principal, expanding the firm's management and construction capabilities.

We emphasize effective communication, rigorous planning, transparency in budgeting and scheduling, attentive project management and outstanding execution. We typically participate in the earliest stages of a project to offer technical input and budget guidance.

Sustainable construction is central to our work. We have built to Passive House and Net Zero standards, earned Efficiency VT's “Best of the Best” award for Energy Efficient New Construction, and completed LEED Silver certified homes.
