President Brian Langlais said he originally anticipated that the company, which specializes in consultant work for utilities and power generators, would have 12 to 15 local employees and a handful of remote workers. “We hired 10 employees last year, so right now we’re at 24 employees total as a company, so we maxed out our local space,” he said. “We actually just hired a couple more people this week. We’re going to be closer to 16 locally and we’re anticipating in the next year to be up around 20 to 25 locally.”
