CARMEL — Four new directors have been added on to the Regional Performing Arts Center Foundation board, bringing the current total to eight.

The new additions are Frank Basile, Ersal Ozdemir, Eric Stovall and John Thompson, according to a news release from an Indianapolis public relations firm.

They join Rosemary Waters, a business manager for Carmel-based Paxton Waters Architecture, and Rollin M. Dick, a consultant with Northwestside Indianapolis-based MH Equity Investors, a private equity-investing group. The two were added to the board in late August.

Also on the board since its formation are Carmel City Attorney Douglas Haney and Nancy Heck, Carmel director of community relations. Both have been described as temporary placeholders for future members.

The board of directors will oversee the Regional Performing Arts Center, under construction at the southeast corner of City Center Drive and Third Avenue Southwest, Carmel.

The center includes a $118 million concert hall as well as two theaters, all of which are expected to open in the fall of 2010.

“I am pleased to welcome our four new directors,” said Dick, chairman of the board, in the news release. “Their experience and proven leadership skills will be invaluable as we work together to chart the course for one of the premier performing arts centers in the United States.”

Board member positions are voluntary and unpaid.

Basile is a retired executive of the Gene B. Glick Co., a writer and a philanthropist.

Ersal Ozdemir is the president and CEO of Indianapolis-based Keystone Construction, which has worked on several projects in Carmel. It is working on a development made up of residences, restaurants and retail areas in the Carmel Arts&Design District.

Eric Stovall is a principle of the Midwest forensic services practice for Switzerland-based KPMG, a global network of firms that offers audit, tax and advisory services with offices in more than 140 countries, according to its Web site. It has an office in Downtown Indianapolis and was hired earlier this year by the Carmel City Council to review the Keystone Parkway construction project and the city’s engineering department.

John Thompson is the president of Thompson Distribution Co., a building supplies wholesaler based on the Indianapolis Near Northside.

“The addition of these highly qualified individuals is a giant step forward in the center’s goal of recruiting a variety of respected professionals from throughout the region,” said Executive Director Steven Libman in the news release. “Their diverse skill sets and talents will prove to be invaluable assets for the Center during this vital growth period.”

Libman has said he hopes to keep expanding the board to 10 or 15 members by next year and maybe up to 30 over time.

He was out of town today and unable to be reached for comment.

A public relations firm handling today’s announcement, Downtown Indianapolis-based three-sixty group, said it had little additional information on the new members of the board.
