Personal Life
I'm originally from New York, moved to Texas in 2005, and I have lived in Plano since then. My wife Elaine is a deaf educator for Plano ISD, and we have been married for 12 years. She works with hearing-impaired children and their parents, providing services from birth until they enter preschool. My stepson Colin attends UNT, and my daughter Vivian is entering 5th grade at Christie Elementary. We have 2 dogs - a miniature Schnauzer named Storm and a poodle mix named Simba. I love to run triathlons, cook, read, and root for the Yankees!
