Brennen is a real estate and project development lawyer who serves as co-leader of the firm’s Renewable Energy Practice Group and as office managing partner of the firm’s Austin office. He advises developers, infrastructure funds, energy companies and utilities, and real estate holding companies on the real estate transactions, land use, and permitting matters at the heart of complex development and infrastructure projects, including renewable and conventional energy, energy storage, data centers, logistics and industrial facilities, and commercial and mixed-use development.

Brennen is a developer’s lawyer. He takes an integrated, strategic approach to development, drawing on broad experience across real estate transactions, land use and project permitting, property tax, state regulatory matters, and project finance to advise clients with a holistic view of each transaction. That breadth lets him see how a decision in one area – siting, entitlement, power, or financing – shapes the others.

Brennen partners with clients at every stage of development, from early site control and acquisition through permitting, construction, financing and investment, and disposition. He has particularly deep experience guiding projects through local land use and siting approvals and increasingly advises on real estate and energy projects across the Mid-Atlantic, Texas and other high-growth markets.
