Pat O’Donnell paused to consider a question: How difficult was it to let his son Scott go from the family home-building business?

“When Scott had to go, I don’t know how to express it,” Pat said.

His construction firm, J. Patrick O’Donnell Inc., had been busy for 30 years. Then one day in 2010, a son became a father’s liability.

“All of sudden when the world changed, I didn’t need Scott anymore,” Pat said.

An older son Patrick also worked for the company but had left months earlier, knowing the family business as a premier builder of multi-million-dollar custom homes was not generating enough to support his salary. But Patrick had always planned to move on in his field, technology and marketing. The home-building downturn provided the fork in the road for him to leave about a year before Scott, even if the business timing was bad.
