Troy-based Doeren Mayhew Monday announced a merger with the Houston, Texas CPA and consulting firm TR Moore & Co., P.C.

Doeren Mayhew said it would remain headquartered in Troy. TR Moore’s 40 employees will bring Doeren Mayhew’s total employee count to 245.

The merger combines two of the firms on Inside Public Accounting’s annual “Best of the Best” top 50 public accounting firms list. TR Moore was one of just two firms with fewer than 40 professionals to be included on the list in 2009.

TR Moore was founded in 1984 and has been serving privately held, mid-sized businesses in multiple industries since its inception. All of its employees will become Doeren Mayhew employees. TR Moore will continue to operate out of its Houston office to service clients.

The merger will allow for Doeren Mayhew to add energy to its list of serviced industries while TR Moore’s clients will benefit by having access to more resources including international tax, corporate finance, strategic planning, wealth management and payroll processing. D

“This merger allows Doeren Mayhew to increase our national reach and continue on a pattern of sustained growth,” said Mark Crawford, managing director of Doeren Mayhew. “We are combining a group of extremely talented and experienced professionals from TR Moore & Company with our own staff of tax, accounting and consulting experts.”

Added Tim Moore, founder, CEO and managing partner of TR Moore: “Given our mutual vision of service and growth, along with shared recognition as best-managed firms, I look forward to what we can collectively accomplish for our clients and staff.”

In recent months Doeren Mayhew also announced the acquisition of the  Troy-based CPA and consulting firm R.W. Frickel, and the establishment of its Financial Advisors wealth management practice.

Doeren Mayhew also recently announced that they have come to terms to acquire the 77,000-square-foot Columbia III building at 305 W. Big Beaver Road in Troy. The majority of that space will become the future site of Doeren Mayhew’s corporate headquarters at a yet unannounced date.

Doeren Mayhew is the third-largest Michigan-based CPA and consulting firm, with 2009 revenues of $39 million. TR Moore reported 2009 revenues of $7 million.

Doeren Mayhew is an independent member firm of Moore Stephens North America, one of the world’s major accounting and consulting associations. It is the only Michigan-based CPA and consulting firm to have ever attained Inside Public Accounting’s “Best of the Best” rating. The firm was founded in 1932. It represents individuals, as well as manufacturers, contractors and builders, retailers, wholesalers, distributors, auto dealers, financial institutions, municipalities, school districts, and non-profit organizations, with a full range of accounting, audit, tax, merger and acquisition, financial, and consulting services.
