Health systems and hospitals use their logos on their buildings, online materials, printed materials and name badges. Logos are pervasive. But what do they mean to the organizations that developed them and the people that see them? Catholic Health World is interested in learning how Catholic health systems and facilities came up with the logos they have and how people have responded to those logos. We'd like to know the symbolism behind ministry logos. Please contact associate editor Julie Minda at jminda@chausa.org with story leads and sources. Please put "Logos" in your e-mail's subject line.
