Chris Caloian Coach


I’ve been a competitive swim coach since 2014. I am joining OAK after 5 years spent with various age groups at Mississauga Aquatic club where I helped athletes to achieve regional and provincial standard times.

I believe technique in swimming is primary when it comes to achieving champion performance and success.

My passion for coaching (swimming) started when my son decided to swim competitively - currently I’m completing my Level 2 coaching certification. I’ve had experience playing soccer, basketball, track and field and was competitive in handball. Aside from sports I have a bachelor’s degree in Engineering.


Susana Escobar Coach

I have 25 years of experience in swimming as an athlete and coach. I am Swimming Canada Level 2 Certified and American Swimming Coaches Association Level 4 certified. 

I am also a two-time Olympian representing the beautiful Mexico where the record books still read my name in 5 events. I swam for The University of Texas -hook'em horns!- graduating with a Bachelor in Kinesiology. I was elected team captain my senior year and during that stage I gained a great deal of perspective on the importance of TEAM! My coaching style will always put team before individual. 

I am very passionate about swimming, and I believe a great coach impacts a swimmer beyond performance, which is why I will always strive to leave a mark in their character. I will use swimming as a powerful tool to help my athletes become better individuals in and out of the water while pursuing their goals!


I am very excited to join the Oakville Aquatics Community and look forward the start of the 2021-2022 swim season!
