I have been a part of swimming almost all my life. As a swimmer I competed from 6 years old through high school starting as the little brother following in his big brother’s footsteps. Eventually stepping away for a few years until my youngest son found his passion for the sport of swimming. Soon after he joined the Marlins, I found myself not only a swim dad but, a swim coach for the Marlins as well. Being a part of this team has been a blessing. Not only do I get to spend time with my youngest son, I have been able to help numerous kids achieve their goals in this sport. My coaching philosophy is simple, work hard, remember your fundamentals and most importantly HAVE FUN!
