An Air Force veteran serving as senior enlisted leader for the 103d Civil Engineering Squadron, he fuses military precision with strategic vision to execute complex federal construction projects and build high-performing teams.
Taking lead at AmeriTech in 2022, DiSilvestro increased total sales from under $1 million to over $125 million.
What’s been your biggest professional accomplishment so far in your career?
I took over AmeriTech as it faced closure with no backlog or revenue. Within two months, I secured $10 million in contracts.
Under my leadership, the company has grown from one employee to more than 70 in three years and has been transformed into a thriving, well-respected, fast-growing federal contracting business.
