The idea of working for a single company for an entire career may seem like a relic from a distant age, but it has worked well for Raymond R. Oneglia in helping guide his family-owned contracting business into the 21st century—and into its own next 100 years—while preserving bedrock values of dedication, loyalty, respect and consensus-building.

Under Oneglia as vice chairman, Torrington, Conn.-based O&G Industries Inc. has thrived and expanded beyond its home state to take part in major projects around the country. But the company has not lost focus on its core New England market, with Oneglia striking a balance between growth and keeping the company, one of the largest privately owned contractors in the Northeast, at a manageable size.
