As I write this, the worst earthquake in a century has destroyed parts of Mexico. Hurricane Irma has wreaked havoc in the Caribbean and made landfall in the Florida Keys.

And Hurricane Harvey’s devastation to my beloved city of Houston is unimaginable. Unlike previous floods, for the first time our family and many friends and neighbors were personally affected. Our home was badly damaged, my car totaled and much of our personal property destroyed. Our children’s schools sustained significant structural harm and thousands of library books, classroom supplies, educational toys and musical instruments were lost. But, most importantly, we are all safe.

In the aftermath of what may total upwards of $180 billion in damages to a vital engine in the country’s economy, the stories of personal risk and sacrifice to save family, friends and strangers are countless. A neighbor college professor braved the raging flood waters in a kayak to bring 38 people and eight dogs to safety on the second floor of her home. A local homebuilder rescued old and young alike on his wave runner. I have seen firsthand people with diametrically opposed world views put aside their differences to assist those in need. I know this period of unity is not permanent, but I will take comfort in it while it lasts.

Even though I may not feel it right now, we are the lucky ones. We are safe, properly insured and have the support of a large network of family and friends. Our kids have returned to schools in temporary locations and we will rebuild and move on.

Not everyone is so fortunate. Many are underinsured or uninsured and face a tough road ahead. Please consider supporting in whatever way you see fit those within and outside the Dartmouth community affected by Hurricanes Harvey and Irma and the earthquake in Mexico.
