Celeste Callahan, Founder

Celeste swept into athletics without a road map, stemming from the unlikely beginnings of a pre-Title IX childhood.  Her upbringing focused on being a lady - manners, dresses and the rule that one should never upstage a man.  She won her first event in 1984 and she never looked back. Her string of cycling and triathlon victories continues to this day.
In 1997, she founded Team CWW and began her coaching career. Its beginnings were inspired by her late best friend, Judy Flannery. Just days after becoming the Rocky Mountain Regional Representative of the newly formed Women’s Commission of USAT, Judy implored Celeste to help support the cause by getting women involved in multi-sport.  That same night, Judy was killed in a cycling accident, leaving Celeste and a group of 60 founding members to carry out Judy's wish.
Since then, that group of 60 women has grown to over 500, with a long waiting list and the distinction of Westword's "Best Triathlon Training."  Celeste grew too, earning her Personal Training Certificate, a first aid card, and became one of the first graduates of USAT’s Coaching Education Program.

Barb Greco, Waves Head Coach 

Coaching and teaching has been part of Barbs life for over 30 years.  When she was fourteen, she started a small business teaching her cousins and kids in the neighborhood how to swim.  She has taken her passion for coaching swimming and studied Education to become a teacher.  She has been teaching now with Denver Public Schools for ten years and currently is a Literacy Intervention Teacher working with 6-8 graders at Kepner Middle School.   Barb also being a fairly active person herself often finds her way to the mountain to telemark ski.  Other interests are yoga, Pilates and are now thinking of completing a few triathlons again this summer.  She also enjoys hanging out with her two Bernese Mountain dogs (Chloe and Frankee). 

Even though Barb’s passion for coaching began in her backyard, she followed suit with it through college and completed her internship and then worked for a year following at the Olympic Training Center in Colorado Springs for United States Swimming.  There her new knowledge led her to a full time coaching position in Arizona with the Arizona Swimming Gauchos.  She worked six years there with many reputable coaches.  Deciding after six years that she wanted to pursue her Masters, she moved back to Colorado with her family and proceeded to study at Regis University.  During her graduate program, she developed a business called triH2O coaching athletes of all levels (mostly adults) how to swim and eventually compete.  Some of her famous clients were Celeste Callahan and Julie Lyons.  Barb loves working with and seeing the progress of the swimming athlete.  As a collegiate athlete herself and now teacher (coach), helping her students and athletes realize their goals is her commitment.
