Christine Grunch-Halberg

18 Tsunami Coach


Christine Grunch-Halberg first found her passion for volleyball when she was in 5th grade. She graduated in 1987 from Coeur d’Alene High School when her volleyball team placed 3rd at the state tournament. She then played one year for North Idaho College where she led the region in multiple defensive categories.

She continued her athletic career at New Mexico State University playing fastpitch for four years. Volleyball continued to stay in her life and after graduating, she discovered coaching through her sister’s high school volleyball team in Michigan in 1994. Since then she has put in over 20 years of coaching girls volleyball at all levels: JV, Varsity, K-8 camps and leagues, and club U12 - U18.

She has gone to many coaches conferences and taken her teams to many college camps where she has learned a variety of ways to help athletes be successful with mechanics, team relationship and unity and competition. The most important thing she has learned is that there are a lot of ways to teach the game and play the game, but the one ingredient that cannot be left out of the game is MOMENTUM!

She believes that if players want to play volleyball and be successful, they not only have to love the game, but find a way to show their passion through their energy, celebrating not just every point, but every great play on the court. Volleyball is played with 6 teammates on a small 30 x 30 court and creating a positive and energetic space will always be hard to beat.
