Cascade Athletic Clubs’ flagship Gresham location at 19201 SE Division Street is a family-owned athletic club operating since 1977, and it now hosts one of the newer pickleball setups in the Portland metro: six indoor courts and four outdoor courts. Programming includes open play blocks, a PB 101 beginner class, leagues, tournaments, and private instruction, with all court use by reservation; tennis and pickleball members can book up to seven days ahead, and other members can make same-day reservations at no cost. The rest of the club is huge: indoor and outdoor pools, a waterpark, group classes, climbing, and racquetball. Members rate it 4.5 stars across 1,022 Google reviews. Doors open weekdays at 4:30 AM.
