Alexis D Keto

CEO/Head Coach


3rd year at New Trier Aquatics
23rd year coaching

Head Coach/CEO
Lead Coach: Senior High Performance

B.A. Northwestern University


Coach Alexis Keto is the current head coach & CEO of New Trier Aquatics in Winnetka, IL. She believes in the well-rounded, socially-aware athlete and infuses this philosophy into each workout, competition & team endeavor. Each swimmer has the potential to be successful, and she feels that coaches should help swimmers discover their pathways to success and to their goals on a personal and individualized level.


Over her 20-plus years of coaching, Alexis has had the good fortune of coaching at every level of the sport - summer league, high school, club and college. In her twelve years at Colorado, the team grew from 4 state qualifiers to 75 state qualifiers, 40+ Sectional qualifiers, Multiple State Record Holders, Junior National (USA/NCSA/ISCA) Qualifiers and  National/Olympic Trial athletes. This tradition of excellence continues at NTA with World Championship Trials and Senior National finalists.  Perhaps her greatest pride, however, is her ability to use her college coaching/recruiting experience at NC State & Northwestern to help athletes find the perfect college - whether at Division 1 schools or NAIA schools. Over 50 athletes have continued their swimming career at the collegiate level with an impressive number becoming team captains during their college tenure. 


Every swimmer has something to give to the team and has something to gain from the sport and Coach Alexis is eager to develop all facets of the athlete. She is also actively involved in the development of the sport of swimming at state and national level, currently serving on national committees, formerly very active in the development of the Western Senior Zone Championships and she has held several positions in the Colorado LSC. Her involvement is not just in governance, as she has coached and managed several local, zone and national camps & teams - most recently as part of the task force for the inaugural 2018 Leadership Summit and as head coach of the 2018 Eastern Zone Select Camp.

Blake J Mock

Director of Operations


I am excited to have joined the New Trier Aquatics Team as Director of Operations in March of 2018.  Swimming has been in my life in some form or another since childhood, swimming for the North Suburban YMCA in the winter and the Northbrook Park District in the summer. I continued my swimming career into high school at Glenbrook North High School. I also lifeguarded and taught swimming lessons during the summer. 

About 10 years ago, I continued my involvement with swimming by joining the official’s side of the pool. I have earned an N3 national status at all levels of officiating. Some of my experiences include:
- Club level, high school, and college meets
- Open Water- State, Zone, Junior Nationals, and Nationals
- NCSA Junior Nationals and Age Group Championships in Orlando
- Junior Nationals
- Nationals
- TYR Pro Series
- Speedo Sectionals
I have traveled to many cities officiating and have met many wonderful people, all dedicated to the sport of swimming. In addition to this role, I also serve as a mentor and a trainer in all aspects of officiating. 

From 2010-2014, I was Vice President of Events for the New Trier Swim Club. NTSC, now NTA,  began a culture of leadership in hosting Official Training Clinics and Recertification Clinics. For myself, I learned how to manage the whole meet experience to provide the best opportunities for our swimmers. 

I have served as Vice Chair of Program Operations of Illinois Swimming  from 2013 - 2017. This position helped me widen my knowledge of swimming from a local club level to a successful LSC level and beyond. I oversaw safe sport and consolidated Rules and Regulations for Illinois Swimming.  Currently, I am General Chair of Illinois Swimming which is a term that runs through 2020.

I have 2 children: Emily, 23, who swam at New Trier. She is currently earning her Doctorate of Occupational Therapy at Drake University. Nick, 20, is finishing his sophomore year at Oakton Community College and plans to go to Franlin College in Franklin Indiana to get a B.A.  I live in Northbrook with my wife Sarah. 

The dictionary says swimming is a sport or activity of propelling oneself through water  using the limbs. Although true, I believe that swimming also builds character, sportsmanship,  and the knowledge that hard work pays off. See you at the pool!
