Lozano immigrated from La Paz, Bolivia to Washington, D.C. in 1972 when he was a university student. He came to study English, but he soon finished his engineering degree in electronics. In addition to working professionally in the security-related industry for his entire career, he and his wife opened an arts and crafts store located in the Old Post Office Building (now Trump Hotel) in Washington, D.C. The store, which lasted for 18 years, sold all kinds of handicrafts and was known for handmade imported Bolivian alpaca wool sweaters. He was always active in local Festivals, and in 1988 founded the Panamerican Festival in Alexandria, Virginia. He provided security at the DC Latino Festival when it was held on the Mall and also had a booth at the Festival. Lozano has been an active leader in the Bolivian community: advocating for regional trade agreements, lobbying for immigration reform for Andean immigrants, and organizing local business councils. Lozano is married to Kathy Lozano and has 10 grandchildren.
