Competitive Team TOLL Prep is currently full and we are pursuing a new outdoor heated site in close proximity to Prep to accommodate more competitive TOLL swimmers. Contact us for more info. 

Fall 2021 stroke/endurance/in-water registration will begin in early August. We will offer classes for all ages and skill levels at Georgetown Prep and St. Albans this fall. Please contact us to receive updates. 

Fall 2021 registration will open in late summer 2021. For information and registration please contact Henry Tollefson at [email protected] or 703-740-7158. Or, you may fill out this interest form and we will contact you.
