Coach Watts will give you just the right mix of encouragement, direction, and a little bit of that push you might be looking for to kick it into high gear!  But don’t worry, she’ll be right there sweating along side of you in the next class! Coach Watts not only trains in the class setting but also one on one for anyone who is looking for a more intimate setting.

David Macia aka “Gringo”

  • CrossFit Level 1 Trainer

Coach Gringo is the newest addition to our coaching staff!  You will never see him without a smile on his face unless he is in the midst of a grueling workout!  He also loves to find creative ways to make your time in his class a memorable one.  If you have any aches and pains or mobility issues Gringo is happy to break out mobility tools and help you work through some of it!


When he’s not coaching you will find him at our local Fire Department where he works full time as a fire fighter and paramedic for the town of Ocean City.
