Bullrock

Four Managing Partners — Gregg Beldock, Amory Beldock, Sacha M. Bacro, and Mike Mills — lead the firm. The operational leadership team includes Partner and COO John Sullivan, Partner and General Counsel Sasha Conroy, and Partner and Head of EPC Andrew Thomas. The firm's website lists these individuals as its senior decision-makers, with no external board or investment committee disclosed.

Bullrock's model is development-driven rather than intermediated. The firm maintains an in-house EPC division headed by a partner, suggesting it originates projects directly and manages the full lifecycle from entitlement through construction. There is no indication of reliance on external developer partners or fund-level sourcing channels.

Bullrock is a single-family office but functions with characteristics of a developer-operator. Its in-house engineering, procurement, and construction capability and dedicated aviation function indicate an operating posture uncommon among allocator-style family offices. The firm's public materials treat development and building as its primary identity.

There is no public evidence that Bullrock commits capital to external energy or infrastructure funds. The firm's website exclusively describes direct development and building of American-made energy solutions. The organizational design — with a Head of EPC and construction management team — points to a balance-sheet direct-investment model.

Bullrock's tagline is "Energy for America. Made in Vermont." The firm's development and building activity is centered on the United States, with a primary office in Burlington, Vermont. A Toronto office indicates some Canadian operational presence, but the public mandate is anchored in American energy infrastructure.
