Centre Partners Announces Acquisition of Den-Mat Holdings

New York, NY (Nov. 16, 2011) – Centre Partners today announced that it has completed the acquisition of Den-Mat Holdings in partnership with Mill Street Partners LLC.

Den-Mat is the world leader in thin, porcelain veneer systems for smile enhancement. The company also offers a wide range of other aesthetic and restorative smile solutions, as well as a broad array of professional dental materials and supplies.

Den-Mat will be led by a new management team consisting of Chief Executive Officer Steve Semmelmayer, Chief Operating Officer Robert Cartagena, and Chief Administrative Officer Todd Tiberi. All three served as part of the executive team at Discus Dental, LLC, prior to its sale to Royal Philips Electronics in December 2010. Under this new team Den-Mat will continue to focus on development of its laboratory products and services, and building out its direct distribution network for both current and future professional dental products.

“We and Mill Street are excited about our acquisition of Den-Mat,” said Robert Bergmann, Senior Partner at Centre Partners. “We look forward to working together to build on the company’s strong reputation and rich heritage of market leadership and innovation. We are committed to making additional acquisitions of dental companies, with a focus on adding new products and technologies as we build Den-Mat into a global dental business.”

“We are excited to have Centre Partners as our business and financial partner,” said Den-Mat CEO Steve Semmelmayer. “Our goal is to expand Den-Mat’s product offerings and provide dental professionals with a wider range of dental supplies and equipment. Continued access to capital and expertise from Centre Partners, coupled with our new strategic direction, will promote additional growth and provide additional value to our customers.”
