Nat Fu
She/Her
Coach
Nat has been playing hockey since she was five years old, when her parents took her to a public skating session, and she immediately fell in love with the game. Growing up in Santa Cruz, California, she was fortunate to have the San Jose Junior Sharks Girls program nearby and played in the organization from U8 through U14.
When her family relocated to the Chicago area, Nat joined the Chicago Mission Girls program, where she competed at the U16 and U19 levels. During her time with the Mission, she helped lead her teams to Illinois State Championships in both 2022 and 2023 while competing against some of the top players in the country.

The Mammoths have earned NCAA Tournament appearances in each of her first three seasons, advancing to the NCAA Final Four twice and finishing as National Runner-Up in 2025. Amherst has also captured two NESCAC Championships during her career, a remarkable accomplishment in one of the most competitive conferences in Division III women's hockey.

When she's not in the rink or the lab, Nat enjoys climbing. She is excited to work with players at the Dynamic Women's Hockey Camp and share the lessons she has learned throughout her hockey journey. Whether she's helping players refine their skating or work on new skills, Nat brings energy, enthusiasm, and a genuine love of the game. She believes hockey is a sport that can challenge and inspire players at every age and skill level, and she looks forward to helping the DWH women take the next step in their development while having fun along the way.
Liz Kemp
She/Her
Videographer/Coach
Liz’s hockey journey started with figure skating lessons in elementary school, but while her sister practiced twirls, her mom watched Liz fly around the ice as fast as she could and quickly realized she was destined for a much faster sport. By the 8th grade, Liz switched to hockey, eventually becoming a three-sport high school athlete (soccer, hockey, and lacrosse) at Concord Academy and playing club hockey for Assabet Valley.
She continued her hockey career playing club ice hockey at Colorado College, and later transitioned her love for sports into coaching. Liz spent 14 years coaching lacrosse, first at Oregon Episcopal School and then at Mount Holyoke College.
Liz has been involved with Dynamic Women's Hockey since its inception. Currently, she serves as the camp’s on-ice videographer. In this role, she captures dynamic action clips of each player, powering one of DWH's most unique features: giving coaches the film they need to provide personalized, visual feedback to help every camper grow. She also designed the DWH logo back in 2019!
When she isn't on the ice or working as a graphic designer and marketing professional, Liz can be found chasing her 3-year-old and the family dog through the woods of Western MA.
