Since it was founded 22 years ago, Naples-based commercial construction firm DeAngelis Diamond has based its expansion model on organic growth. Whether geographic or product type expansion, the company has minimized risk in moving into new markets.

The result has been steady growth: founding partners John DeAngelis and David Diamond have built the firm into a 200-employee company with 2017 revenues of $366.4 million. That’s up 36.6% over $268.3 million in 2016 revenues.
