Welcome to Sandsharks!

The Sandhills Sandsharks Swim Team was founded in 1982 by Marsey Peterson, an ASCA Age Group Coach of the Year and mother of current SSS Board President Lindley Fleury (High School All-American, Collegiate All American, Indiana University, National and World Masters Champion).  Marsey moved to the Sandhills with her husband when he retired from the military.  She realized the community lacked competitive swimming and access to swim lessons. Over the ensuing decades, her efforts and those of the coaches who followed her yielded a growing, successful team.

Head Coach, Susanne Cooper, holds a Masters in School Counseling from UVA and has spent over 20 years working with students and swimmers ages 5-18.  She swam competitively for the Lynchburg Piranhas and William & Mary; her two children are on the Pre-1 and Senior squads. She has been involved in the local swimming community for 12 years.

Senior Coach Harry Traystman was a High School All-American and State Champion in Connecticut; in college (Indian River, Florida; Queens, Charlotte), he was a two-time Team National Champion, eight-time individual National Champion, 17-time Collegiate All-American and two-time team captain.  His coaching career began at New South Swimming, where he served as an Assistant and Head Coach, coaching both Age Group and Senior swimmers.  He then moved on to Trinity University in New Haven, Connecticut, to be the Assistant Men’s and Women’s swim coach, where he helped coach their first NCAA Qualifier in over 35 years.

The Sandsharks follow USA Swimming and the ASCA’s developmental model to nurture and challenge our youngest, novice swimmers through our college-bound high school swimmers.  Family and academics come first; swimming is just one of many sports and activities in our athletes’ lives.  We emphasize quality instruction and the opportunity to grow at a rate appropriate for each swimmer with the goal of seeing our senior swimmers reach their potential.

The work ethic and camaraderie gained through practicing with integrity, effort, and focus pay off in giving our swimmers the skills for success both in and out of the pool; both now and later in life.

Two SSS 2018 graduates are now on swimming scholarships at UNC-W and William & Mary.  We also have sent swimmers on to UNC-CH, Duke, Loyola, Lenoir-Rhyne, Wingate, UVA, SMU, Washington & Less, Brown, and McGill, to name a few.  Many Sandsharks have assumed Team Captain positions. A 2020 graduate will be swimming for UNC-Pemproke.

The Sandsharks are a 501 ( c ) 3 non-profit, managed by a board of past and current parents and coaches. Our board’s diversity is one of our many strength: parents represent public, private, and charter schools; five of our members swam at the collegiate level (one of whom swam for SSS) and together represent five decades of Club and College level swimming. 

In addition to our Year Round team, SSS runs two Open Water meets per year at Lake Echo in Seven Lakes, the Moore County Swim League (summer league), a mastery-based lessons program, and we participate in USA Swimming’s Make A Splash Foundation to bring lessons to underserved populations. We support the Boys and Girls Club, Moore Buddies, and Special Olympics.

Our move to the Southern Pines Pool in 2018, a larger pool with more space for dryland, means expanded programming and control of our own water.  Plus, our location is convenient to other youth activities, shopping, and restaurants.
