Coaches & Directors

We are here to support your swimming needs.

If you have questions related to workouts, meets, events, goal setting, or other "in-the-water" related concerns, please contact one of the coaches.

For all questions related to administrative concerns (such as dues, safety, or policy issues) please contact one of the board members.

Meet the Coaches

The coaching staff is attentive to our swimmers. As one parent commented upon coming from another team, "My son has had more coaching attention here in one week than he had in a whole season on his other team."  

BAT has a tradition of talented and well-trained coaches. They are carefully chosen for their love of swimming alongside their desire and proven ability to develop champions in and out of the pool.


Coaching Staff

Bobby Yribarren

Head Coach


Coach Bobby spent the first half of his coaching career in central and northern California making two stops in Texas before deciding to brave the New England winters. He believes in putting the FUN in fundamentals and training the right energy systems at the right times--quality over quantity. He takes the long view when it comes to student-athlete development and wholeheartedly believes in the power of sport as a vehicle for transformation. 

Coach Bobby has developed:

  • one Southern Zone Select Camp Athlete
  • one national top 10 age grouper
  • Far Westerns finalists
  • TAGs finalists and champions (Texas Age Groups)
  • Junior National qualifiers
  • Senior National qualifiers
  • Olympic Trial qualifiers 
  • one women's D-1 NCAA qualifier (200/500/1650 Freestyle)

With an extensive background in exercise science and sports psychology, Bobby completed his Masters of Arts in Communication at University of the Pacific. When he's not on deck, he enjoys going on long runs and takes particular delight in hearing others say "Oh, this is vegan?"

Nathan Barton

Assistant Age Group Coach


Nathan Barton comes to BAT after 5 years at the Boys and Girls Club Watertown. He has worked with swimmers of all ages and takes special pride in working with those with learning disabilities.


Coach Nathan learned how to scuba dive at age 10 and became PADI certified shortly thereafter. Having been on 70+ dives in oceans across the world, it is this fascination with water that led to his love of competitive swimming. Joining the Minuteman High School swim with no formal training, Nathan applied himself and developed into a competitive swimmer and leader on the team—serving as captain of the team during his senior year season.


Coach Nathan loves giving back and celebrating success alongside his swimmers. He believes in the power of the Individual Medley and consistent effort.


He is currently pursuing a Bachelor’s Degree in Criminal Justice and Education.

Harry Delgado

Assistant Age Group Coach


Coach Harry loves learning new things and working with swimmers of all ages. It's pushing the little the things and seeing how much can be accomplished in the day to day that keeps him motivated. He looks forward to swimmers showing up ready to roll and leaving each day feeling proud of the work they did. 

Coach Harry is a facilities manager at Harvard; he also serves as an assistant for the Belmont High School Boys Team and is heavily involved with Cambridge Sea Dawgs.
