Natalie Janelle Ramos

Age Group Coach


Hello my name is Natalie Ramos. As the youngest daughter of four, I’m twenty years young. Next fall I will be transferring to UCD as a Human Development major with an emphasis in community nutrition. I competitively swam on various teams for seventeen years as well as one year with our Darts.  I have coached summer darts and currently coach our Gold swimmers. I enjoy working out, volunteering on weekends, organizing my room, preparing nutritious meals and spending time with my sister and friends. I believe the most important concept to instill in my swimmers is the reality that no one can judge a good effort. 

Russell Haussermann

Age Group Coach


Russell has been involved in competitive swimming since he was four years old. He was a highly successful club swimmer for the Monterey Bay Swim Club and a record holding high-schooler, but opted out of collegiate swimming to pursue other athletic interests.

He currently is the head coach of the Masters program at the Davis Athletic Club. From his experience comes a passion and dedication to the sport.
