Sami Leonis

Sami Leonis

Program Manager

My name is Sami Leonis and I grew up in San Jose, CA. Growing up, I was a water baby. I learned how to swim at a very young age and started swimming competitively when I was 4. I continued competing until I was 17, when I then moved to San Francisco to pursue a degree in Kinesiology. I graduated from San Francisco State University in May of 2016 with a Bachelors of Science in Kinesiology. Shortly after, I decided to move down to sunny Southern California to try something new! I am a die hard fan of all bay area sports teams- 49ers, Giants, and Warriors- and have a passion for food, music, and the water. I plan on bringing a lot of positivity, fun, and high energy to Premier Aquatics, and am looking forward to what's ahead!

Will Mocnik

Will Mocnik

Lifeguard Supervisor

My 5 year goal is to get through community college at saddleback and transfer to a four year college, most likely out of state. In my free time, I enjoy spending time with my friends and girlfriend and going to the gym. One of my favorite hobbies is basketball; I love playing pick up games with friends, as well as watching games on tv. My favorite things about working for Premier Aquatics are our socials where we all get together, hang out, and get to know each other more! If I was stranded on an island I honestly don’t think I could live without In-N-Out.
