This is Heather's 4th year coaching with UMLY

College:   1993 B.S. Elementary Education Miami University Oxford, OH

                 2000 M. S. Educational Counseling Southern Connecticut State University New Haven, CT

Swimming/Coaching experience:      At age 8 Coach Heather started summer swim league after she passed all the levels of swim lessons. The swim instructor suggested she try out for the swim team. She cried behind the blocks before her first race. Her dad turned to her and said, “Just try it once, and you will never have to do it again”. She was hooked after her first swimming race!

At age 11 she started year round swimming for Radnor Aquatic Club and then for Suburban Swim Club. She moved to Clearwater, FL at age 15 and continued age group swimming with West Florida Lightning Aquatics. After high school she swam for Miami University.

Heather moved to Fairfield County, CT after graduating college. She began to swim competitively for a Master’s swim program at the Westport/Weston Y. Knowing her education background, the aquatics director asked her to work as a swim instructor at the Y. In the mornings she instructed campers and in the afternoons she taught private lessons in backyard pools. She also taught private swim lessons for 14 years. While she was teaching fourth grade in Weston, CT, she was asked to be the assistant swim coach at Weston High School. Periodically, she would coach an age group session at the Westport Y, while attending grad school and teaching full time. In 1997 Heather met her husband Eric at the Westport Y through the master’s swim team.

In 2009 Heather and Eric relocated to the Philly area. It was during that time that their children Brendan and Delaney started swimming for UMLY. Heather still swims frequently at UMLY. Every year for their anniversary Heather and Eric choose a different open water swim to compete in to celebrate their love of swimming!

Currently, Heather is a college counselor at Delaware County Community College.

What does Heather like about coaching?:    Swimming is about getting a swimmer from point A to point B in the quickest and most efficient way possible. The joy of coaching comes from teaching a swimmer the life lessons that are learned, while pursuing that endeavor.

Brennah Ross Coach Age Group 1
College: 2015 B.S. in Economics, The College of New Jersey
Swimming/Coaching Experience: 
Coach Brennah followed in her older sister’s footsteps and was persuaded into joining UMLY’s swim team as a 7 year old.  She quickly fell in love with the sport, and swam with UMLY for 11 years.  During her time at UMLY, Brennah was a YMCA national qualifier and finalist.  As a senior, she was the recipient of both the Sue Clayton and Joey Guest awards for leadership and team spirit.  
During her collegiate swimming career she was a four-time NCAA All-American, and individual NCAA qualifier in the 200 butterfly.  She currently holds the TCNJ school record in the same event.  Brennah was voted the New Jersey Athletic Conference’s ‘Rookie of the Year’ in 2012 and ‘Swimmer of the Year’ in 2014. 
Brennah enjoyed her experience at UMLY so much she decided to return to the program as a coach in 2015. She started out coaching AG1, and has since gained experience coaching athletes of all ages and abilities.
What I like about coaching at UMLY: I have always believed that the most important part of swimming has nothing do with swimming at all. The culture at UMLY is about developing strong work ethics, creating invaluable friendships, building confidence, and having a blast along the way. That is what made me love swimming so much as an age grouper, and what drew me back as a coach. My favorite part about coaching at UMLY is being able to provide that experience to another generation of swimmers, and being given the opportunity to share my love of this sport with others.
