Annette Spicer Nielsen grew up as one of the youngest of seven children in an aquatic swim/water polo family. She began swimming at the age of 4 years, where her parents Donald and Anna Spicer helped in begin the Fullerton Aquatics Swim Team (FAST).

And to this day still holds team records.

From 1989 to 2013, Annette was the Head Age Group coach of FAST. There she developed and guided many swimmers to the Jr. Olympics, Jr. National, Sr. National and Olympic Trials.

Annette believes that technique and the focus on middle distance swimming will make a swimmer well rounded, with the opportunity to perform and excel in the events they love, whether it being distance or sprint swimming. She attributes a lot of her achievements and her love of coaching to her mentor, the late Kevin Perry, FAST coach 1991-2008 (coach/mentor of Olympic 2012 Gold Medalist, Tyler Clary).

Annette's biggest supporters are her husband Kory and 2 beautiful girls Nicolette and Paige. She is so happy to be a part of the EAST family values and the philosophies in which the team stands for.
