MILWAUKEE — Tom Phillips rejoined Rev Group as chief operating officer (COO) on April 1, the company announced recently.

Rev Group is the parent company of Type A school bus builder Collins Bus Corp. Rev’s brands also include vehicles for the commercial, fire and emergency, and recreation markets.

As COO, Phillips will work closely with Rev’s business units to ensure that they are executing on the company’s key supply chain, quality, cost, and new product initiatives.

Since his return from retirement, Phillips has already been working with the company’s finance and business leaders to identify opportunities for further growth, profitability, and customer service, according to Rev.

“I am excited to have Tom back on the REV team full time,” CEO Tim Sullivan said. “We all look forward to working with Tom to continue on our strong trajectory of growth.”

Phillips will assume many of the duties of Marcus Berto, executive vice president, who was terminated on March 26. According to Rev, Berto’s dismissal was “due to personal conduct inconsistent with the company’s policies.”

“Mr. Berto’s termination was not related to the company’s business, operations, financial performance, outlook, or financial reporting,” the company said in a statement.
