COVID-19 UPDATE: As Kitsap county is in Phase 2 of Washington State’s reopening plan, we are now holding small-group training sessions which are limited to five students. Because of the limitations, classes are open to current students only at this time and reservations are required. As soon as things open back up and we are able to accommodate more students, we will be taking new students again. To receive notifications about the Jazzercise and Pilates Mat classes, please email and indicate which program(s) you are interested in.
Note that Castor Guzman is offering personal/small group training sessions, and Deanna Dewell currently has three strength/Pilates classes per week at the studio. They may have openings. Contact them directly at or All students attending classes at the studio during this time must sign a waiver which details WA state’s COVID-19 Safe Start guidelines.
