Meet the Team Coordinator and Coaches!


MacKenzie Bammer - Piranhas Coordinator 

My name is MacKenzie Bammer and I have grown up around the water. I began my swimming journey here at the Dolores Bengston Aquatic Center at the learn-to-swim programs we offer. I then transitioned from swim lessons to a recreational swim team. I swam for the PVC Dolphins swim team from the age of seven to eighteen. I am now swimming at the collegiate level for Las Positas Women’s swim team. I have been working at the DBAC pool for more than five years and have overseen numerous Piranha swim meets. This year I hope to create a supportive, team atmosphere that will allow all swimmers the opportunity to improve and be the best that they can be. I hope to provide a safe, organized, and fun atmosphere for the swimmers, their families, and all who join us this summer.


Marc Gauthier - Head Coach 

I grew up in this league, starting with the Club Sport Tidal Waves when I was four and bouncing around to a few other teams until I graduated. I also played varsity water polo and swam for Amador Valley HS. This will be my third summer with DBAC, beginning as a swimmer and then assistant coach, and now as head coach! I just finished my freshman year at the Brigham Young University of Hawaii, where I'll be majoring in marketing and minoring in hospitality and tourism management, and I hope to one day open a chain of restaurants. My number one goal for this season are to build our team as a community. By creating a fun, but still hard working, atmosphere, I hope to help our swimmers improve their speed and form as well as make lasting friendships. I believe that swimming is an essential life skill, and I hope to pass along my love of the water to you and your children!


Ruby Quinn - Assistant Coach

My name is Ruby Quinn and I have been swimming competitively for about five to six years. I am currently swimming for the Pleasanton Seahawks; I enjoy swimming distance events. I attend Amador Valley High School and enjoy my math and art class. I hope to attend BYU and study design. I am very excited to start my first year as an assistant coach on the DBAC team. Swimming is such a great way to get exercise and a useful skill that you can carry throughout your life! I have a few goals for this season. One of which is to make sure that swimming is fun. I want our swimmers to remember that this is a chance for them to work at something that they are good at and truly enjoy it. It is easy to get caught up in who came in first or what your time is. Swimming is about accomplishing your goals and working to better yourself. As a coach, I hope to encourage our swimmers to work hard and improve their stroke while having fun. I want to help kids improve their technique-- better technique is the best way for a swimmer to get faster. I plan to integrate drill work along with speed work to make sure that our swimmers perform their absolute best! I am looking forward to get started this season! Go Piranhas!


Gemma Schiaffino - Assistant Coach


Hello my name is Gemma Schiaffino, and will be one of the assistant coaches of the DBAC Pirahnas swim team this summer. I have been swimming since I was ten. I started on a summer swim team and then in high school I started swimming more competitively. I have gained a passion for swimming and am glad to be able to share it with the team. I will be a sophomore in the coming up fall semester at a small school in Irvine called Concordia University. My major is elementary education and hope to be a teacher once I graduate. I have been working at the aquatic center for several summers, but this will be my first being involved with the Piranhas. I am looking forward to get to know and work with this team, helping to improve your child's swimming, making sure they are having fun, and come to have a passion for it just as I did.


Teesa Heidari - Assistant Coach

What's up guys! My name is Teesa Heidari and I am a sophomore communications major at San Diego State University. I started swimming with DBAC when I was six years old, so I am a born and raised Piranha. From there I continued swimming at Amador Valley High School, where I began playing water polo. It turned out that water polo was my true calling, and I ended up getting in to SDSU as an athletic recruit for their water polo team! A goal of mine for this season is to help improve each individual on the team by getting to know everyone's personal strengths and weaknesses. I am fortunate to have had many coaches who have given me the individual attention I needed to reach my full potential, and I want to be able to make the same impact on someone else’s career. Success is a combination of talent and hard work, and I can’t wait to coach this group for this season and to get DBAC to the top! :)
