Floyd Padilla

My name is Floyd Padilla and I was born and raised in Twin Falls, Idaho. Growing up, I enjoyed being active in sports like football, wrestling, running, boxing, and weight training.  Later on, I joined the Navy after High school and was stationed on the USS Nimitz in Washington state.  I then attended Green River College in Seattle, where I received my degree in Criminal Justice and Photography.  Currently, I enjoy working on my photography business and working with autistic students.  I also teach students photography and videography in an after school club, where we work on our school yearbook, website, and put a news announcement together that we air every Friday.  In my free time, I enjoy helping others, love to ski, longboard, bike, kayak, hike, and most of all spend time with my lovely wife.
