Steph Mattrey

Head REC Coach/Assistant US Coach

Email

Coach Steph hails from a small town called Bethlehem in eastern Pennsylvania.  An avid athlete all her life, she was drawn to swimming at a young age.  Stephanie was a competitive swimmer from the age of 6 to 18, competing at both Rec and USS levels.  Her training, coupled with her slow twitch muscles, morphed her into a 100 and 200 butterflier, as well as a competitor in all of the distance freestyle events, although she still likes elementary backstroke and wishes this could be a “thing” at meets.  Yes, coach Steph experienced the challenges of long distance training yardage, but wouldn’t have it any other way.  She fell a little more in love with the sport each day as she grew up.   

Having decided not to swim in college, however, Stephanie still couldn’t seem to stay away from the pool. Amid her double major in Psychology and Creative Writing at West Chester University of Pennsylvania, she studied animal behavior extensively and sat as the long standing editor in chief of the college literary magazine.  She also played collegiate level water polo for 5 years during her stay there, while thoroughly soaking up all the lovely gems that Philadelphia offers. Tournaments up and down the Atlantic coast consumed her time, happily, most weekends.  Stephanie gleaned so much insight from her experience in water polo, that her coaching and training expertise in the competitive swimming world has become very well rounded.  

After college, Coach Steph coached a startup USS team for a short time in 2004-2006 called Argo Aquatics. She worked with all age groups and served as head Dryland coach for that team as well.

Coach Steph is also an Acupuncturist and Chinese Herbalist, and has been licensed by the states of California and Massachusetts since 2010.  She has a bustling private practice in Hadley, MA, where she treats all kinds of medical conditions and has a unique niche for women’s health and the complex treatment of eating disorders.  

In her spare time, Coach Steph now trains for the international sport of Strongman.  During her first year of competition, she qualified for North American Strongman Nationals in Missouri later this year. She has found a passion for Olympic style weightlifting due to this sport, and brings this passion and knowledge to her dryland coaching for the Tritons.  It is safe to say that Coach Steph thoroughly enjoys picking up heavy things and putting them back down!  Her study and interest in lifting has also fishtailed into the study of body mechanics when it comes to how resistance training can support the improvement of technique in the 4 swimming strokes, as well as starts and turns.  

When she is not on the pool deck, holding tiny needles, at the gym, or sleeping, Stephanie proudly mothers her three daughters, two of whom are swimmers on the Tritons.  Coach Steph adores nature and makes a point to get out into it in some form or another each day, regardless of the weather. New England makes her happy and she resides in Amherst with her family.

Neel Sekar

Assistant Coach/College Swim Adviser

Email

Coach Neel was born in Natick, Mass and grew up around the Natick area. He spent most of his early life doing sports and began swimming lessons from infancy. In addition to swimming, Neel also played basketball, baseball, soccer, ultimate frisbee, and skateboarding while growing up. He originally tried out for the Hockomock Area YMCA Lightning at age 7, and made the team when he was 8, before transferring to Bluefish Swim Club at age 13. Neel swam competitively until 18 when he decided to attend UMass Amherst.

After deciding to attend UMass, and not to swim at Rensselaer Polytechnic Institute, Neel decided to try triathlons as he had also always been a decent runner. In summer 2016 he participated in his first event, the Westboro Sprint Triathlon. He plans on continuing competing in triathlons and hopes to one day do an XTerra and a Spartan Race.

Neel is currently enrolled at the University of Massachusetts in Amherst, where he is pursuing a degree in Electrical Engineering with a minor in Chemistry.

Oliver Wyeth

Assistant Coach

Email

Ollie is 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, he began learning to swim as a toddler to prepare himself for the huge swells on the beaches. It wasn't until  he was around 8 years old that he began to swim competitively. At age 12, he saw his first national success which would carry through till he graduated high school. During his time in high school, he would have the opportunity to travel to a few countries as a member of both the New Zealand junior team and New Zealand Olympic Development team.
 
In 2014, Ollie was recruited by the UMass Amherst varsity team as a 500 freestyler, and 100/200 backstroker. During his time at college he was able to win multiple individual medals, two conference championships, acquire NCAA cuts, and captain the team his senior year. In 2018, he put up the cap and goggles and realigned his focus to an area of study he was passionate about. This resulted in continuing his studies focusing on gaining a Master of Science in Business Analytics in 2019 and in turn finding a job in Northampton. With the extra time created now that he is not training 20 hours a weekin the pool, he is excited to be on deck in a different capacity to dhare his passion and experieinces in the sport.
