Coaching Staff

Sean Horan

Head Coach

Email

Coach Sean has spent almost 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 (2), when they make appearances at social events.

Hi Stingrays! My name is Coach Megan and I am so excited to be a part of your team and the VSA League once again.

I grew up here in Danville and spent my summers swimming for the Blackhawk Hox with my three siblings. While a part of that program, I developed a passion for competition, technique, and team spirit. I hope to inspire this in all of you as well!

For the past few years I coached the Moraga Ranch Swim Team in the OMPA League. I also coach competitive water polo with 680 and the Olympic Development Program. I can't wait to learn more about swimming from Coach Sean, continue to work on my coaching skills, and get to know all the swimmers and their families! See you at the pool!

Hi Stingrays! I am very happy to be back for my third year of coaching for the Stingrays. Many of you know that I started my swim career as a six-year- old on the Stingrays and received my retirement cane and golden goggles when I was 18. I swam throughout high school at the Athenian School and continued at Chapman University in NCAA swimming. I have experience in very competitive environments like our County meet, NCS Championships and NCAA league and championship meets. I am very comfortable teaching all strokes, dives, turns and other technical swim skills for all ages. Feedback for swimmers is something I find very important in order for them to succeed inside and outside of the pool. I look forward to a competitive and fun summer! Go Stingrays!

I will be a senior at Chapman University in the fall. I started swimming when I was 6 for Diablo Country Club and switched to year-round in 8th grade. I swam for Orinda Aquatics, Vikings, DVC, and now Chapman University. Last year I was an assistant coach at LMYA and I can’t wait to be part of Sycamore Stingrays this year!

T.J. McCarty

Little Stingers Assistant Coach

Email

T.J. has been a Sycamore Stingray since he was 5 years old! He swam throughout his high school years for Monte Vista and graduated in 2016. He is currently going to school at Sonoma State University, finishing up his freshman year.
T.J. has two volumes when he's on the pool deck: loud and louder! You can't miss him when he's behind the blocks, either helping a swimmer prepare for their next race or cheering on stingrays that are already in the water. He loves to have a good time with his teammates but knows when it's time to get down to business. His ultimate goal this season is to help swimmers improve their strokes and have a great time while doing so.
