The philanthropic community can help ensure our elected representatives make the right decisions. Private citizens can help make a difference in whatever way they are able -- writing a check, donating in-kind contributions, calling or writing their elected representatives, volunteering time to a nonprofit.

Most important, we have to hold our legislators accountable on Election Day. If your representatives don't support gun reform, then don't vote for them. A coalition of people working toward the greater good is the essence of our democracy. Follow us on Twitter @CNNOpinion.
