Michelle Casillas is in the fifth year of her second stint as the diving coach at UC San Diego in 2014-15. She previously served in the same capacity for two seasons from September 2004 to March 2006.
Both the UCSD men's and women's squads won their sixth consecutive Pacific Collegiate Swimming & Diving Conference (PCSC) titles in 2014. Casillas took four of her divers, three men and sophomore Allyson Cohen, to the 2014 NCAA Championships. Senior Luke Calkins advanced to the main draw and became a first-time All-American with an eighth-place effort in the three-meter event.
Prior to the national meet, Calkins was the NCAA's recipient of the Elite 89 award for having the top grade-point average of any male swimmer or diver participating in the championships in Geneva, Ohio. Calkins also left the program as a three-time Capital One Academic All-American, and earned a prestigious NCAA Postgraduate Scholarship.
In 2011-12, the Tritons duplicated their second- and third-place showings, respectively, at the NCAA Division II Swimming & Diving Championships in Mansfield, Texas. Casillas qualified three men's divers to the NCAA meet, after Tyler Runsten had won a third straight PCSC crown in the three-meter event. She was named PCSC Men's Diving Coach of the Year.
In 2010-11, Casillas coached Runsten, then a sophomore, to a second-place finish on the three-meter springboard at the 2011 NCAA Championships in San Antonio, Texas. He also took fifth in the one-meter.
With Runsten winning from three meters at the 2011 PCSC meet, Calkins, a freshman at the time, placed third, and Patrick Cohen was seventh. In the one-meter event, Runsten took second while Calkins was fourth and Cohen was sixth.
Since Casillas has been with the Tritons, UCSD produced the first two NCAA All-American divers since the program moved up to Division II for the 2000-01 season.
Casillas served as a master trainer/manager at Guaranteed Fitness, a health coach at StayWell Health Management, a gym director at The Little Gym and a personal trainer at Snap Fitness prior to returning to UCSD. Certified by the National Strength and Conditioning Association (NSCA) as a Strength and Conditioning Specialist (CSCS), Casillas has nearly eight years of training and coaching experience.
Casillas competed as a varsity diver for the University of Nevada from August 1997 to January 2000, earning All-Big West Conference honors four times. She then joined the varsity diving team at Florida State University, where she competed from August 2000 to March 2002 and was a three-time All-Atlantic Coast Conference performer. She graduated from Florida State in 2002 with a bachelor's degree in sports management.
Casillas resides in Temecula with her husband and two children.
