Best Squat 942 Best Bench 534 Best Deadlift 683 Contact Info 712.301.2364 I am passionate about my family just like I am passionate about the gym. I'm married to my wife, Andrea, and together we have 4 children. I have been powerlifting since I was in high school. I've competed in many powerlifting meets since 2015 including the Arnold Classic in Columbus, OH and the Kern Open in San Diego, CA. I have an extreme passion for lifting and really love helping others succeed in their fitness goals, whether it be for competition (bodybuilding or powerlifting), sports endurance, to build muscle, lose weight or just to stay active. I've worked with people ranging in age from 12 to 66. And don't forget to ask me about the joke of the day.
