Following her graduation in 2013, Rachel remained active in the aquatics world by coaching the DIII Gators of Notre Dame of Maryland University as well as managing the well-known Meadowbrook Aquatic Club, home to NBAC swim teams and Michael Phelps.

Ali Sensintaffar

AAPC & Co-Head Coach


Ali started swimming competitively when she was eight years old for the Highlands Ranch Seahawks. She continued swimming throughout high school for Highlands Ranch High School Girls’ Swim & Dive team and swam for the Colorado State University club team for one year. Ali’s best event was the 100 butterfly and went to State for both her summer league and high school league in that event. Besides for butterfly, she specializes in short distance freestyle.

Ali has been coaching and teaching swim lessons at the age of fourteen and has worked with all levels of swimmers from infants and toddlers that have never been in the water before to adults who still compete. Many of her swimmers have gone on to compete on year-round club teams, high school teams and college teams.

As a coach, Ali focuses on technique work and strives to instill a love of the sport in her swimmers. She fully believes that a swimmer's development is a joint effort between the coach and the swimmer. She can give her swimmers the tools to succeed, but without the drive or the hard work put in by the swimmer, progress would not be possible.

Ali graduated from the University of Colorado – Denver in 2018 with a degree in Creative Writing. She is currently attending Western Governor’s University to obtain her Master’s in Secondary English Education. She plans to teach English at the high school level and then go on to be an English Professor at the collegiate level.
