Steph Mattrey

Assistant Coach

Coach Steph was born and raised in Bethlehem, Pennsylvania.  An athlete of many sports, Steph gravitated toward swimming the most, starting at the age of six.  She swam competitively at the Rec, YMCA, and USA levels until she was 18.  Coach Steph led her high school team as Captain for two years while dominating her region in the butterfly and distance freestyle events.  She also swam for two US level club teams, Bethlehem Aquatic Club and Atlantis Aquatic Club, both in the mid-Atlantic region.  Coach Steph went on to play five years of NCAA water polo at West Chester University of Pennsylvania.  West Chester competed all up and down the east coast and, along with UPenn, was a critical spearhead in the return of competitive women’s collegiate water polo to the region. 

Steph landed in Massachusetts with her family in 2012 after relocating from Los Angeles where she completed her Masters degree in Acupuncture and Traditional Chinese Medicine.  She maintains a private acupuncture practice in Florence where she sees all kinds of patients while specializing in women’s health.  When coach Steph isn’t seeing patients, on the pool deck, weightlifting, or sleeping, she can be found mothering her three daughters, two of which are swimmers on the Tritons, and walking her sweet Golden Mountain Dog, Onyx.

I am a native of New Zealand that used swimming as a means to move to the United States. New Zealand is surrounded by water with the furthest inland point being only 74 miles. As a result of this, I began learning to swim as a toddler to prepare myself for the huge swells on the beaches. It wasn't until I was around 8 years old that I began to swim competitively. At age 12, I saw my first national success which would carry through till I graduated high school. During my time in high school, I would travel to a few countries as a member of both the New Zealand junior team and New Zealand Olympic Development team.
 
In 2014, I was recruited by the UMass Amherst varsity team as a 500 freestyler, and 100/200 backstroker. In my time at college I was able to win multiple individual medals, two conference championships, acquire NCAA cuts, and captain the team in my senior year. In 2018, I put up the cap and goggles and realigned my focus to an area of study I was passionate about. This resulted in me attaining my Master of Science in Business Analytics in 2019 and finding a job I love in Northampton. With a bit more free time now that I am not training 20 hours a week, I look to get on pool deck to share some of my experience.
