Sentinel exits air quality consultant to Gryphon

Gryphon Investors has partnered with management in its acquisition of Trinity Consultants from Sentinel Capital Partners.

Sentinel Capital Partners has exited air quality consultant Trinity Consultants in a sale to fellow lower mid-market firm Gryphon Investors, the firms announced in separate statements. Gryphon partnered with Trinity’s management and employees on the deal, the terms of which were not disclosed.

Sentinel also partnered with management in its 2007 acquisition of Trinity, in which the company’s management maintained a “significant” ownership stake, according to Sentinel partner Eric Bommer. The firm made the investment through its third fund, which raised $319 million in 2005. This is Sentinel’s only exit in 2011.

The firm has been active as a buyer this year, closing four new investments. Sentinel made a pair of acquisitions in the healthcare sector, picking up WellSpring Pharmaceutical and National Spine and Pain Centers, as well as heating products manufacturer Chromalox and military vehicles producer Critical Solutions International.

Sentinel, which manages $1.25 billion in capital, typically focuses on lower mid-market companies in the aerospace, defense, business service, consumer product, distribution, food, restaurant, franchising, healthcare service and product and industrial manufacturing industries.

“I think that our market hasn’t been impacted nearly as much [by the economy], if at all, compared to the larger-size buyout market,” Bommer told Private Equity International.

San Francisco-based Gryphon also operates in the lower mid-market with a focus on the business service, healthcare, education and consumer product and service sectors. The firm typically invests between $25 million and $75 million in traditional buyouts, leveraged build-ups, and growth equity investments.

Gryphon could not be reached for comment.
