Nathanael Marino Head Coach

Swimming in general has been one of the most influential parts of my life. From a very young age, I found a love and a drive to continuously better myself and enjoy the time spent with new friends along the way. I later had the opportunities to surround myself with some of the greatest mentors and coaches a young high school athlete could ask for. They pushed me and guided me into the direction that I find myself today. I rose through the ranks while in college at SUNY Maritime, while helping the Privateers gain a 9th consecutive conference championship my freshman year and proceeding to be a team captain my last two years. Once I finished college, I knew in my heart that it was my time to give back to the sport that has given me so much. Along with my first job out of school as an engineer for the Navy; I joined the team at Tide Swimming as a part time coach. There I was mentored by two of the greatest, Jack Roach, previous USA Olympics Team Assistant Coach '04, '08, '12, and '16, and Mike Salpeter, Head Agegroup Coach. Both men have spent time training and guiding me to be the best coach and mentor to any person who has a want, a drive, and most importantly, a love for the sport of swimming.
