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.
