Contact Jen:

Jen Lavely

Jen is a Colorado native – experienced athlete and coach – who credits her success to the influence of athletics in her life; specifically a positive and healthy relationship with sport during her formative years. She swam competitively through college at Willamette University and there began competing successfully in triathlons. Running became her primary sport during graduate school at Yale University School of Public Health. Thereafter, she returned to Colorado; formed and coached for 10 years the Peak to Peak Swim Team (youth and masters swim teams), and worked as a county public health director. 

 She worked full time for seven years as a coach for athletes of all ages and needs on Peak to Peak Swim Teams, Indian Peaks Running Club, Boulder Track Club, Fleet Feet, Nederland Middle and High School Cross Country, Track, and Field teams, and Boulder Valley School District’s Nordic Ski Team. She has also worked as a PE teacher at Chinook West and privately to clients around the world. She is excited and grateful for the opoportunity to coach you on RACE and at RallySport. 

Jen believes anyone can do anything so long as they are willing to try. She is eager to meet athletes at this crossroads of curiosity and momentum, and feels the best motivation is positive. Her coaching philosophy, which she keeps fresh by constant study of and participation in sport, is simple. 1) The 1 or 2 hours every athlete spends with her should be the best hours of their day; 2) It is always fun while tackling the learning curve; and 3) Every athlete gets the same, positive, dignified, and empowering attention from their coach regardless of ability, needs, or goals. She genuinely feels that the bright spot in her every day is the opportunity she has coaching YOU!

Kimberly Goodell

Kimberly’s passion for swimming began in California, where her enthusiasm for all things aquatic eventually won out over her extreme aversion to the sinister black lines on the bottom of the pool. By age 14 she was on her high school’s Varsity swim team, where the stage was set for a future in swimming, fitness and elite level competition.

Kimberly is now an accomplished multisport athlete, with 63 podium finishes and 29 career wins in triathlon, road racing and open water swimming. She currently competes on the Ironman circuit as a professional triathlete.

Kimberly is also an endurance sports coach and personal trainer with  certifications from the National Academy of Sports Medicine and the American Council on Exercise. She has been coaching swimming for six years and is certified through US Masters Swimming, and USA Swimming.

Her goals as a coach are to foster the love of swimming in people of all ages, and to teach her swimmers to leverage the discipline, teamwork and courage learned through sport to create confidence and success in every day life.

She competed through the collegiate level, specializing in the 200 fly and 200 IM, and transitioned into triathlon at the completion of her college swim career. Rachel is now racing triathlon as a professional.

Sarah Jirkovsky

Sarah has been a swim instructor since 2003 and employed at Rally Sport since 2010. She swam competitively from age 7-17 and was a lifeguard for many years.  She very much enjoy teaching all age groups and abilities. However, Sarah’s area of expertise is infant swim, special needs, and children that are timid of the water.  She teach Aquashrimps at Rally (6 months – 3 years old), which is a fun and interactive course that a parent or guardian are in the water with the child and will learn how to introduce them to kicking, floating, water safety and going underwater.

With all Sarah’s classes, she customizes them to the individual and creatively develop each class to be unique and comprehensive.  Whether you are practicing water safety skills or perfecting strokes, Sarah believes swim should always be exciting and fun.

Contact Susan:

Susan Einberger

I swam competitively on various Boulder County teams for 20 years. I still love the water and swim in and coach the RallySport Masters classes. I understand that, unlike running or cycling, swimming is not intuitive for most people. Proper form and technique supersede pure fitness. I will break down the components of swimming into manageable drills that will build upon each other to develop your swim strokes.  If you can independently swim one pool length, I can help you become a smoother, faster, and more confident swimmer.

Contact Greg:

Greg Rogers

Greg was born in New Jersey and learned how to swim in the Atlantic Ocean. His older brother and him soon graduated to a nearby community pool where he had my first experience jumping off a high dive. Living in Michigan and attending a camp in Pennsylvania for two months every summer allowed for thousands of lake swimming experiences. He was involved in high school team swimming and later enjoyed the west coast and Pacific Ocean while attending college in the Bay Area. Greg’s favorite kind of swimming is a nice river that runs into an alpine lake. He is an avid canoe and kayaker with many solo trips under his belt. He has snorkeled in Hawaii and the Caribbean and has probably gotten his feet wet in every state. Greg has worked at Rally Sport for the past 10 years and continues to teach both group and private lessons

Tom Swift

Tom was born in Chagrin Falls, Ohio where he learned to swim at a very young age. However his love for being in the water began when he first experienced swimming in the ocean on vacation. His enthusiasm for the sea lead him to scuba diving, and he completed the rescue diving certification at only age 14. He then went on to swim competitively for two seasons in High School. Tom loves working with kids, and in addition to teaching proper technique he wants to make lessons fun and engaging!

Outside of coaching, he studies English Literature, Music, and Art and CU Boulder as well as participating in the CU Marching Band. He also enjoys playing guitar, skateboarding, reading, riding motorcycles, writing, and painting in his free time.
