Our Founders

Doug Collatz

Jeff Ottani

Doug and Jeff met in the late 1980s while working for one of Nantucket’s top contractors. They wanted to bring a more personal touch to their work, so they started their own company and completed their first residential project near Children’s Beach—quickly earning a reputation for exceptional quality and reliability.

Their reputation grew throughout the island community, and their commitment to craftsmanship and attentive service built lasting relationships with local homeowners.

Today, Brant Point Building remains a close-knit, family-oriented business dedicated to serving homeowners with care and integrity.

For instance, when our air conditioning failed on a sweltering July day, they had an HVAC expert at our house within hours, showcasing their strong relationships with local service providers.

In addition to caretaking, BPB has managed three major renovation projects for us, overseeing everything from architectural services to construction. Each experience was seamless, and their professionalism and deep knowledge of Nantucket make them invaluable. We trust no one else with our home. — Carol H.
