SMS Assist has named Dave Sweitzer as chief sales officer and executive vice president for the Chicago-based technology-driven facilities maintenance and management company.

Sweitzer, 50, previously served as strategic business director for Waste Management and vice president of client services at Oakleaf Waste Management. He joins an expanded SMS Assist executive team that includes Vice President of Client Services Michael McMath, formerly of Wal-Mart, and Chief Operating Officer Matthew Pitts, who previously controlled maintenance for more than 2,200 Home Depot locations.

In his role with Oakleaf, now a part of Waste Management’s Sustainability Services Group, Sweitzer increased annualized revenue from $60 million to $750 million. He held key client-facing roles both before and after Oakleaf’s merger with Waste Management, building strong relationships within the food and retail industries.

“Dave has the experience and vision to help guide SMS Assist as we support the movement to national core services aggregation,” says Michael Rothman, SMS Assist chief executive officer. “He will be influential in the development of our business platform and the expansion of our departments, making sure our customers always come first as we continue to grow and evolve.”
