Christina Colosimo, DO, MS, a clinical assistant professor, was featured in a Cronkite News article examining current trends in gun violence. While national and local gun violence rates have fallen to their lowest levels in decades, rates in the Southwest remain higher than the national average. Colosimo noted that communities of color in Tucson continue to be disproportionately affected and emphasized the need for early education and prevention, saying, “We need to be going into schools and talking about gun violence in elementary school, in middle school … and [establish] better firearm curriculum.”
Colosimo leads several key prevention initiatives, including the hospital-based Gun Violence Prevention Initiative with more than 30 community partners and a school-based program active in three districts. These initiatives include regular visits to middle and high schools to deliver firearm safety and violence-prevention education directly to students. In addition, she chairs the Injury Prevention Committee for the Eastern Association for the Surgery of Trauma, serves on Tucson’s Community Violence Advisory Board, and is the director of Injury Prevention and Outreach and associate pediatric trauma director at Banner University Medical Center — Tucson. Her ongoing work remains essential as regional disparities persist.
