Northwell Health held panel discussions Tuesday with people impacted by gun violence who are demanding change.

Sandy and Lonnie Phillips lost their daughter Jessi to gun violence in the 2012 Aurora, Colorado, movie theater mass shooting.

"My daughter went to a movie in 2012 and went to see the Batman premiere in Aurora, Colorado, and she never came home," Sandy Philips says.

They were just a few of the families who shared their story at Northwell Health's Center for Gun Violence Protection with hopes of finding an end to the gun violence crisis.

Dr. Chethan Sathya says the discussions are about firearm safety and what Northwell Health can do as a health care organization to provide resources and have conversations with patients.

"We know if we can talk to patients about gun safety, gun violence, it can save a life," Sathya says.

Northwell Health brought the Philips together with others who lost loved ones to gun violence.

One of the initiatives is to build a coalition of support and awareness with medical professionals, advocates and communities to help prevent injuries and deaths related to guns.

Shenne Johnson's son Kedrick was murdered in Queens in 2010.

"I'm speaking from my heart as a Black woman in America," says Johnson, of Moms Demand Action for Gun Sense in America. "I buried three people, that is too much."

Lonnie Phillips says it's "mind-boggling" that nothing about gun violence has been done on the federal level and that a background check bill that failed 10 years ago would have saved thousands of lives.

Northwell Health is asking other health care systems and hospitals across the country to join them in their effort.
