Rosen Consulting Group adopts Andersen brand

Rosen Consulting Group (RCG), a real estate and economics consulting firm, will adopt the brand of Andersen, a San Francisco-based tax consultancy.

The rebrand arrives three years after RCG became a subsidiary of Andersen. The boutique firm, which had approximately a dozen employees at the time of acquisition, continued to operate as RCG. 

RCG was founded in 1990 by chairman Ken Rosen, professor emeritus at the Haas School of Business at the University of California, Berkeley. The firm has expertise across strategic real estate consulting, investment analytics, market assessments, and forecasting.

“For more than 30 years, our team has worked alongside Andersen professionals to deliver market intelligence and strategic clarity,” Rosen said. “Adopting the Andersen brand enables us to expand the scope of our services while continuing to provide the same quality expertise our clients have come to expect.”

Andersen’s real estate industry practice delivers solutions in real estate appraisals, property tax appeals, fund accounting, cost segregation, and tax strategy to clients including investors, funds, institutions, sovereign wealth funds, and families.

“Ken and his team are known for producing analyses that shape market perspectives,” said Mark Vorsatz, global chairman and CEO of Andersen. “Their adoption of the Andersen brand reflects our ability to provide clients with seamless, multidisciplinary services and reinforces our commitment as the benchmark for quality and independence in professional services.”

Andersen was founded in 2002 as Wealth & Tax Advisory Services (WTAS) by former Arthur Andersen tax practice partners as a subsidiary of HSBC USA. In December 2007 a management buyout made WTAS an independent firm.

In 2013 the firm launched WTAS Global as an association of independent professional services firms. In 2014 WTAS changed its name to Andersen Tax LLC and WTAS Global became Andersen Global. Andersen Tax rebranded as Andersen in 2019.

Andersen today has approximately 2,200 professionals across 26 cities in the US. The firm provides tax, accounting, valuation, and private client services to individuals and companies.

Andersen Global has more than 44,000 professionals worldwide and a presence in over 600 locations through its member and collaborating firms.
