Coach Sean has spent over two decades teaching kids to be collaborators, learners, and swimmers. He empowers his athletes with peer leadership at every age level in order to develop physical, mental, and social skills that will apply to all aspects of their lives.

Sean has coached with all four of his siblings, even discussing skill techniques over family dinners and Thanksgiving reunions. Through hard work and experimental innovation, they developed a style of team leadership that is dynamic and unique, which empowers all athletes and enables program development. Sean has gained valuable insights during his pilgrimage to the peninsula, where he coached the SOLO Aquatics and Eichler Swim Teams simultaneously, and is happy to be bringing that knowledge back to the East Bay. You may meet his lovely wife, Lily, and his daughter, Violet, or little Finnick who all participate in the Sycamore swim programs.

Hi Stingrays! I'm Miranda Duarte and I'm very excited to be back this summer. I've been competitively swimming for over 13 years and coaching for 7 years. I love working in and out of the water, but I'm looking forward to making this season as fun as possible. I graduated from Cal High but now, I'm going into my third year at the University of the Pacific in Stockton. I sing in a jazz/r&b band called Laminated List, I love music, and I am always snacking. Let's make this a great season. Go Stingrays!

Hi Stingrays! I am excited to be back and coaching you guys this summer! I've swam for the Stingrays for 10 years and have jr. coached for 6 of those years. I swam all four years at Monte Vista High School and am currently at Cuesta College. At Cuesta, I am on the water polo team and the captain of the 2024 conference-champion swim team. I love coaching and have spent this spring as the Head Coach of the league-winning varsity and junior varsity boys swim team at Morro Bay High School. I enjoy working with all age groups and I specialize in butterfly, freestyle, backstroke, dives, and underwaters. Go Stingrays!

Hey Stingrays! I’m Mateo Fernandez, and I’m excited to be back for my second year coaching with Sycamore! I graduated from Monte Vista High School last summer and will be studying business at Miami University this fall. I swam for Sycamore for 9 years, and I’m ready for another awesome summer around the pool. You’ll see me on deck and in the water coaching throughout the season. I love coaching breaststroke, freestyle, and turns, and my favorite event is the 200 Free Relay. I can’t wait to bring good vibes, high fives, and a few ridiculous Speedos to the pool this summer!

Hi Stingrays! We'll get my bio and lesson info up soon!  I am a lifeling Sycamore Swimmer who helped run the Little Stingers program for the past few seasons.
