Belle Vee B. Gentry, founder and president of a Washington highway construction company, has become the first elected woman president of the District of Columbia Chamber of Commerce. She succeeds Joseph McLaughlin of McLaughlin Oldsmobile.

In its annual elections, the 700-member volunteer business organization also chose five other officers, including four women. They are:

*Inez P. Austin, president of Design Innerphase, as first vice president.

*Belva Newsome, director of the D.C. Commission on Housing, as corporate secretary.

*Patricia Shannon, vice president for business development at D.C. National Bank, as financial secretary.

*Michele Hagans, president of the Fort Lincoln New Town Corp., as treasurer.

Stanley Straughter, senior vice president of DAC International, was selected second vice president.

Members of the Chamber applauded Gentry's appointment, calling her an energetic and experienced business owner. Andre Gandy, a three-year member of the board and chairwoman of the chamber's business and economic development committee, said Gentry's "leadership style is very dynamic. She gives a lot of herself."

Gentry, whose family has long been involved in the construction industry, six years ago founded Ebone Inc., a construction company specializing in highway and sewer construction. Gentry now runs the business with her husband.

Gentry said she would continue to promote the chamber as a forum for pooling the interests of the business community and increasing the clout of its members, particularly small and minority-owned firms. BANKING, FINANCIAL SERVICES
