Ultimate Ninjas will celebrate the grand opening of Milwaukee’s first
dedicated ninja play and training gym on Saturday, April 27 from 10 a.m. to 2 p.m. The
new 16,000-square-foot Ultimate Ninjas gives all ages the authentic ninja warrior
experience with obstacle course training classes for toddlers and youth, birthday
parties, summer and school break camps, open gym, a youth competition team, adult
fitness classes and special events. The Oak Creek gym, located at 400 W Bell Ct, suite
350 in Oak Creek, is owned by pro ninja Mike “The Stallion” Silenzi, a ten-time
American Ninja Warrior veteran. Managers will include Milwaukee’s own Nathan and
Marquez Green, twins who have competed on many seasons of American Ninja
Warrior.
The grand opening celebration of the national franchise’s ninth location will include
open play in the main gym where kids ages 6 and older will have the opportunity to try
the iconic obstacles identical to the hit television show. The cost is $15 for one hour
and $25 for two hours. Open play for kids ages three through five will be in the
separate 4,000-square-foot Lil’ Ninjas area with obstacles custom-built for younger
children such as scaled-down versions of the truss, warped walls, climbing wall,
monkey bars, trapeze and rings. The cost is $10 per hour. There is no charge for the
accompanying parent who must be present the entire time. Guests will have the
chance to win raffle prize giveaways every hour, including free class passes, free
summer camp sessions and a free birthday party. Spots are limited, so preregistration
is recommended and can be made at
This Oak Creek location will feature the nation’s highest-quality, engineered obstacles
and agility courses including one of the only 18.5-foot mega curved walls. Other
obstacles include the double salmon ladder, ring slider, lache bars, flying squirrel,
quintuple steps and many more obstacles for kids, adults and super athletes to try,
practice and master. This is the first Ultimate Ninjas to feature the big dipper, a curved
pipe slider track and the second to feature a trampoline and foam pit. Obstacles are
changed frequently to add challenge and variety.
