During its annual gala celebration Saturday, the Ibero American Chamber of Commerce named Lila Dominguez its 1983 Hispanic Businessperson of the Year and Aragon Trucking Corp. of Arlington its Hispanic Small Business of the Year.

Dominguez is managing partner of Alta Enterprises Inc., a real estate management and investment firm in Washington. A native of Puerto Rico, she has lived in Washington for 35 years and is a member of the National Conference of Puerto Rican Women and the Puerto Rican-American Women's League. Dominguez is a founding member of the Ibero-American Chamber of Commerce and a former chamber vice chairperson.

She currently heads the chamber's public affairs committee. She also is a former board member of the Mayor's Minority Business Opportunity Commission and the Barney Neighborhood House, which provides social services in the city's Adams Morgan neighborhood.

Aragon Trucking Corp., a refuse trucking company, was established in March 1982 by President Carlos Aragon, Vice President Carlos Rodriguez, Secretary Rolando Ortiz and Treasurer Eduardo Rodriguez. With the company's single truck, Aragon and Carlos Rodriguez serve about 100 continuing accounts in Washington and Northern Virginia. The company grossed $100,000 in its first year of business, from March 1982 until March 1983.

The Ibero American chamber, founded in 1976, assists Hispanic businesses setting up in the area, and provides a link between the Hispanic community and local Hispanic businesses and the same sectors in non-Hispanic communities. The chamber is also involved in international trade with Hispanic companies elsewhere.

Washington's Hispanic community is estimated at 17,000 by the 1980 Census, but a survey conducted last year for the local Hispanic radio station, Radio Mundo, found an estimated Hispanic population of 50,000 in the city. ASSOCIATIONS
