Dive into Crimson Aquatics: Your Journey Starts Here!

Step One: Tryouts

Embark on your swim team journey with a tryout—a crucial first step to assess readiness and determine the appropriate training level. Tryouts take the form of a drop-in practice and must be successfully completed before team registration.

For Waltham (Brandeis University) or Brookline (Dexter Southfield School) locations: Contact Coach Emily Ellison at [email protected] to schedule your tryout.

*Note: While not everyone may make the team initially, our open-door policy encourages continued improvement through lessons, paving the way for future tryouts.

Athlete placement in training groups is skill- and age-based, exclusively determined by our qualified coaches. Crimson Aquatics, being a competitive swim team, expects regular attendance at practices and meets.

Step Two: Registration

Once your swimmer passes the tryout and is placed in a training group, it's time to register:

  • Visit www.crimsonaquatics.com, click on the BOSTON site, then navigate to REGISTRATION.
  • Indicate the group and location (e.g., Age Group 1 + Dexter).
  • Read the registration document carefully and reach out with any questions.
  • Contact Team Manager Adriana Marmolejo at [email protected] for financial inquiries.
