United Site Services, a leader in portable sanitation and temporary fence rental services, this week named Asterios Satrazemis CEO and Scott Jamroz chief financial officer. Satrazemis, former CEO of BlueLine Rental, succeeds Ron Carapezzi, who has served as president and CEO since 2009. Carapezzi will transition into the role of chairman and is expected to remain a meaningful equity partner in the business.

United Site Services was acquired by Platinum Equity in August 2017.

“Under Ron’s leadership as CEO, USS achieved remarkable growth and is well-positioned to take the next step,” said Platinum Equity partner Louis Samson. “We thank Ron for his contributions and are pleased the business will benefit from his continued support and partnership.”

Most recently, Satrazemis and Jamroz were CEO and CFO, respectively, at BlueLine Rental. BlueLine was the fourth largest general equipment rental provider in North America. The two executives led a turnaround of BlueLine under Platinum Equity’s ownership that resulted in the sale of the company last year to United Rentals for $2.1 billion.

“Since we acquired USS, the business has proven to be a strong platform for growth, both organically and through M&A, with significant untapped potential ahead,” said Samson. “Asterios is the perfect fit to drive the next phase of the company’s evolution. As we saw first-hand with the success of BlueLine, he’s an outstanding leader and a terrific partner. We are excited to work with him again.”

Satrazemis brings a depth of experience in the rental industry to USS, not just in the general equipment space, but in the specialty sector as well. Before serving as CEO of BlueLine, Satrazemis was president of the Americas for Aggreko, an international leader in temporary power and temperature control solutions.

“No other site services provider has the legacy and reach of USS,” said Satrazemis. “I’m excited for the opportunity to lead the team in expanding our position as the leading player in the market while continuing to deliver a best-in-class experience for our customers.”

“I have the utmost confidence that we are well-positioned for the next phase of growth led by Asterios and the leadership team,” added Carapezzi.

United Site Services, with more than 100 locations across the United States, is based in Westborough, Mass., and specializes in portable toilet and temporary fence rental services.
