Chicago, IL – BDO USA, LLP, one of the nation’s leading professional service organizations, today announced an expansion into Pittsburgh through the addition of 250 partners and staff formerly with Alpern Rosenthal. A top 100 accounting firm, founded in 1961, Alpern Rosenthal is one of the largest firms in Pittsburgh and brings additional staff in Philadelphia and South Florida to BDO. The firm provides a full range of accounting and consulting services to a diversified client base of privately-held and public companies in the construction, manufacturing, medical, high-technology, nonprofit, professional services, real estate, retail and wholesale industries. The combination of BDO and Alpern Rosenthal is effective December 16.

“I want to welcome all of the partners and staff of Alpern Rosenthal to BDO. Alpern Rosenthal's prominent position and deep community ties provides us with an ideal entry point into the Pittsburgh market,” said Wayne Berson, CEO of BDO USA. "Alpern's entrepreneurial culture, commitment to superior client service and work life balance made them a natural cultural fit with BDO. Combined with other recent additions our firm has made in Anchorage, McLean, Minneapolis, Philadelphia and San Antonio, this is powerful evidence that our growth strategy is continuing to gain momentum around the country."

Alexander Paul, who joined Alpern Rosenthal in 1983 and was named president of the firm in 1998, will serve as the Managing Partner of the Pittsburgh office of BDO USA. Margaret J. Tanney, who has more than 25 years of experience in public accounting, will be responsible for managing the Pittsburgh assurance practice, and Celeste M. Suchko, who joined the firm in 1994, will manage the tax practice. Brandon Otis will lead the business valuation and litigation support practices for BDO Consulting in the Pittsburgh market.

“We are extremely excited to be joining BDO USA, a national firm with a very compatible practice philosophy and culture to our own,” said Alexander Paul. "With our entire staff moving to BDO, our clients will still receive the local, hands-on service they have always valued from our firm, but will now have access to a wider array of services, broad industry experience and the resources of BDO’s extensive global network. These expanded resources will help our clients grow and become even more successful.”

Alpern Rosenthal has been recognized by numerous business and industry publications for its rapid growth and workplace accomplishments. It has been named one of the “Best of the Best” managed firms by Inside Public Accounting, a "Top 100 Firm" by Accounting Today and one of "Pittsburgh's Top Workplaces" by the Pittsburgh Post Gazette.
