Trinity Consultants, Inc., an international environmental consulting firm that specializes in industrial air quality issues, and Sierra Research, an air quality and pollution control research and engineering firm, announce the completion of their merger.  The merger will enhance client service for a wide variety of engineering, testing, modeling, and analytical expertise related to air quality planning, permitting, and compliance.  Both companies assist industrial sector clients with air quality regulations and compliance management; additionally, Sierra serves public and private sector clients with a wide range of vehicle, fuel and air quality planning  support.

Paul Greywall, Trinity’s Director of Business Development, commented on why the merger makes sense.  “Although both companies have a strong air quality focus, we each bring somewhat different skills to the market.  The Sierra team’s deep knowledge of mobile air emissions sources, the California market, and state air quality planning programs are synergistic to Trinity’s long-term growth plans.  We believe clients of both Sierra and Trinity will benefit from our combined resources and expertise.”

According to Gary Rubenstein, a founding Partner at Sierra, “Trinity’s strong senior management team and its broad geographic footprint are especially appealing.  This transaction will facilitate expanding Sierra’s unique skill set across a broader geographic area while retaining our air quality focus.  We are excited about the additional resources available to both our clients and our staff.”
