Steve Carroll is the CEO & co-founder of Kelso Industries, a national MEP services platform uniting HVAC, mechanical, plumbing, and electrical companies.
In just a few years, Kelso went from a gritty, nearly-broke first acquisition to 29 acquisitions and $1B+ in revenue.
Steve breaks down the bruises and the blueprint: why their first year almost killed the business (including a single job that wiped out a year of profit), the switch from “buy and replace” to a partner-and-keep-the-owner model, how they finance growth without overpaying, and the operating system (recruiting, cash, WIP discipline) that lets local brands scale without losing their soul.
