Meet Your 2022-2023 Coaching Staff!


Sara Holcombe

Sara has coached at many different places - Northern Lights, Shakopee, and Burnsville, and at many different levels; 18's - 12's. Her favorite level is the beginners. It's so fun to see the look on their faces and feel the excitement wen they start putting all of their skills together. She appreciates how they are all so supportive of each other on and off the court. She loves the energy of the 12's. She is also very competitive. She enjoys the close matches the most - fighting and persevering as a team, and coming out on top is so fun to be a part of during the match. She hopes to instill perseverance, hard work, friendship, and the love of volleyball to all who play and watch the game. "If you are not having fun, you are not playing volleyball."
