The nonprofit Friends of Hoyt Park & Pool, which operates TOSA Pool, The Landing and the Grand Hall, raised money to build the pool, which opened May 28, 2011. FOHPP has a 55-year lease with Milwaukee County and does not receive taxpayer support. The pool is named in honor of the project's lead donor: The TOSA Foundation.

TOSA Pool at Hoyt Park offers affordable memberships for families and individuals with daily admission rates that welcome visitors from across Southeast Wisconsin. Our strong focus on health and wellness is enhanced by swim lessons for children and adult fitness classes provided by our partnership with Wauwatosa Recreation.

In 2013, the Friends of Hoyt Park & Pool opened a new seasonal beer garden, The Landing at Hoyt Park, to both create a supplementary revenue source for pool operations and to create a new space for fellowship that enriches the vibrancy of our community. People of all ages come together and build the relationships that make our neighborhoods strong.

In 2015, the historic Grand Hall was renovated to preserve and build on its 1930s-era craftsmanship and extend The Landing beer garden usage. In addition to public gatherings, like Packers and Badgers viewing parties, the hall is available to rent for family celebrations, class reunions, birthday parties, business meetings, club banquets and weddings.
