I’m Coach Kris and I am the Head Coach for the Houston Area Life Times. I have been with Life Time since March of 2018. I’ve coaching here in the Gulf LSC in Houston for 17 years. I was born in raised in the Houston area. I learned how to swim at a very young age where I developed a passion for the sport. We are a swimming family. My father is a Head Coach and Brother a Head Age Group Coach in the area. My two kids Erin (13) and Rowan (11) also swim and compete at meets as well for Life Time Swim Team. 

The kids I have coached range from Learn to Swim all the way to Olympic Trials. I believe in encouraging each swimmer to pursue their goals and abilities positively. The sport of swimming is something that each person can take with them for life. I try to teach the swimmers qualities such as: dedication, determination, time management, goal setting, team work, and sportsmanship.  

When I am not coaching you can find me in the country fishing, hunting, and anything outdoors.

Head Site Coach - Sugarland

I am the head coach of Life Time Swim Team Sugar Land. I am currently a student at Wharton County Junior College with plans of transferring to the University of Houston by fall 2017. I will be majoring in Kinesiology and would like to use my degree to study competitive swimming.

My love for swimming started at a very early age. My mom believes it first started when we visited our family in Trinidad and Tobago and I was about 3 years old. My mom said I was completely fearless of the water. After I completed swimming lessons she put me on a summer league swim team. I began competing for the Mission Center/Lakemont Marlins when I was about 8 years old I stayed with this team until I was about 13. Through summer league I found my initial love for swimming. After summer league, I began to take swimming more seriously, so I joined a club team named Sienna Plantation Aquatics. This is the first time I was officially part of USA Swimming. I then moved to another team, Southwestern Aquatic Team, the summer before my first year of high school. For my first two years of high school, I was part of the Global Studies Academy at Clements High School. At the time, CHS was also one of the best high school swim teams in the state, so of course I joined. By my junior year of high school, I unwillingly moved to Travis High School. Then things began to look up, as I then joined their swim team as well as qualified for regionals. By my senior year I was one of the team captains and qualified for regionals again.

I have thought about swimming in college, but for now I am swimming with Masters Swim at Life Time and I love it!

I have been inspired by my coaches and all the friends that I have made in the swimming community to begin coaching. I want to have the bonds with my kids that I had with my many coaches. I first started working with Life Time Fitness in April 2015 as a swim instructor, and by the end of the year I was head coaching. I have only been coaching USA Swimming for a little less than 2 years. I strive to be the best role model/coach. By helping better my swimmers as athletes, as well as trying to have a genuine relationship with each of them and support bonds with their friends and coaches that can and will last a lifetime.
