Michele J Hartwick

YWSF Program Coordinator



Michele stumbled into the swimming world and the YMCA Westside Silver Fins through her son, after he joined the team following a knee injury.  Her time here started out with her volunteering at a swim meet as a timer, followed by the next meet as Clerk of Course and then Meet Director. Her love for all things administrative ultimately brought her on as a part time staff member in 2015, primarily as a liaison between the PAC and the swim team office.  Since then she has taken on more responsibility within the swim team administration and the YMCA and in early 2017 was given a full time position as the YMCA Aquatic /YWSF Coordinator.  

While her son has left for college, Michele will continue her work with YWSF and plans on helping the team continue its success and make it even stronger moving forward. 

Randy D Gertenbach

Senior Group Coach


Hi! I am Randy Gertenbach and I coach the Senior Group. I started swimming competitively at the age of 8 in El Centro, CA, with Imperial Valley Desert Aquatics. I swam club and high school, which paved the way for me to swim in college at the University of Pittsburgh.  At University of Pittsburgh, I was an 11-time Big East Champion, which ranged from the 100 and 200 breastroke, and 200 IM.  I qualified for NCAA’s in 2002, 2003, 2004 and was a 3 –time All American in the 200 breastroke.  After graduating from the University of Pittsburgh with a Bachelor’s degree in Applied Mathematics, I then pursued my Master’s Degree in Educational Leadership and Cross-Cultural Teaching Techniques at the University of California, San Diego.  I am currently a High School Math Teacher, as well as being an assistant swim coach on this amazing team!!

My coaching philosophy is commitment, teamwork and pride in what you do will can take you anywhere. I believe that we are all “teachers” when it comes to swimming, and we learn and grow every day. 

I am a person that loves to give back to his friends and community, and coaching swimming is something where I can do give back to both.  I love that I am able to share my love of swimming with our athletes. Swimming has shaped me and my individualism, and I feel it can do the same for our present and future swimmers.

He was also selected as the 2013 Arizona Age Group Coach of the Year by Arizona Swimming. Ryan is extremely dedicated to the success of his swimmers and feels they respond to his dedication with enthusiasm and lots of hard work. Ryan believes that 'perfect practice makes perfect' and success in swimming is attributed to consistently applying good technique training. Ryan also feels that if his swimmers can see regular progress in workout sessions and if they are frequently placed in race-type scenarios that they will be much more confident when they step up on the blocks in a meet situation.

Coach Ryan has a contagious passion for the sport of swimming which can be observed on a daily basis by his swimmers and colleagues. Ryan swam for the Goodyear Sharks as a youngster and later for the West Valley Aquatics Club (WSF), Glendale Gauchos and Agua Fria High School.

Kate Brinson

Bronze Group Coach


Hi! I am Kate Brinson and I coach the Bronze group. I started swimming competitively at the age of 5 in Tucson, first with the Desert Dolphins and then with the Tucson Swim Club (now Tucson Ford). I swam club, high school and college intermural while in college in Texas.  Previously, I was the head coach for a club team in Washington State and a head high school head coach in both Texas and Arizona. I have a Bachelor’s degree in Exercise Physiology from Texas State University and Master’s in Education from Northern Arizona University. I have also spent time in Australia at the University Sydney as a researcher in their Exercise Physiology Department, studying movement with athletes and patients who were quadriplegic and paraplegic.

My coaching philosophy is hard work and determination can take you anywhere. I believe that it is my job as a coach to not only coach our swimmers, but to help shape our kids to become better versions of themselves. We can teach our swimmers how to win, but as coaches it is also our jobs to teach them how to lose, how to be humble enough to learn and respectful enough to be true to themselves. 

The sport of swimming has given me so much throughout of my life and no matter where I have traveled or lived the water has always felt like home. I love that I am able to share my love of swimming with our athletes. I think Coach Meg said it best; "I want to give back to swimming what swimming has given to me."
