Mark your calendars, Boston: Mayor Marty Walsh has proclaimed that this Tuesday will be Diane Guerrero Day in honor of the “Orange Is the New Black” actress, who plays the sassy Maritza Ramos on the Netflix show. Guerrero (pictured), a Boston native who in 2015 was selected by President Obama to be a Presidential Ambassador for Citizenship and Naturalization, is being honored for her advocacy for immigration reform. She will receive a special tribute from Walsh Tuesday evening at the We Are Boston Gala, a multicultural celebration — complete with food, music, and dance — put on by the Mayor’s Office for Immigrant Advancement and held at the Boston Park Plaza Hotel. The annual event, which draws hundreds of guests, will be hosted this year by Maria Stephanos of WCVB-TV (Channel 5). Along with honoring Guerrero, Walsh will present leadership awards to Richard E. Holbrook, chairman and CEO of Eastern Bank, and John B. Cruz III, president and CEO of Cruz Companies. The two are in good company; past recipients of the We Are Boston Leadership Award include Senator Edward Kennedy, David Ortiz, Yo-Yo Ma, chef Ming Tsai, and author Junot Diaz.
