Kristal Haralson
Powerlifting Head Coach
Hello, I am a graduate of The University of Texas Rio Grande Valley with a BS in Rehabilitation Services. My passion for fitness started through high school sports and continued to be a part of my life through adulthood via recreational fitness, until I discovered CrossFit in 2016. CrossFit has offered the competitive atmosphere and community team environment I had been missing. Since then I have spent the last 3 years competing in team and individual CrossFit competitions. This is my second year teaching ACL- Life skills at San Marcos High School. As a strength and conditioning coach for tennis my goal is to ensure that our athletes are equipped with the skills necessary for achieving academic, athletic and social success.

I began my career at San Marcos High School in 2015. Most of my life has been spent around the world of swimming. As a Rattler Coach, I believe in holding our athletes to the highest of standards and expectations in the pool, in the classroom, and in the eyes of the public. Swimming is a sport that not only fosters competitive spirit and builds every muscle in the body, but it also encourages life long self discipline. The San Marcos Rattler Swim Team is a family of high performing student athletes.
