Personal Quote:

The middle child of five siblings born to Darren James Gallagher and Elena Lopez (of Irish and Cuban backgrounds, respectively) and a stepson of Vincent Casey, David Gallagher has two younger brothers, Killian (who is autistic, which is why David is a devoted member and spokesperson of the organization CAN/Cure Autism Now) and Kyle Casey and two younger sisters, Michelle Casey and Kelly Casey.
