JJGym - Circus and Stunt Training Space Reviews
This is a welcoming and wonderful training space. The owners are so kind and generous. The price is unbeatable. I wish there was more open slots for Open Gym so I could come all the time!!
September 13 · 620buttonI once reserved a portion of the space to train their on their online calendar but never came back. This was a while back but I was so traumatized I still think about it to this day! So here is my review:I reserved the space for the first time and followed all instructions on their website: where to park to not disturb neighbors, how to enter, etc. I showed up 5 minutes early and went inside. There was Jeri sitting on the floor with a kid on an iPad. Immediately she starts yelling at me to get the hell out in the most aggressive way imaginable; tells me the door was shut and what in the world am I thinking just barging in? (Um — I was thinking I reserved and paid for the space, and assumed it was ok to come in?) She talked me down and treated me in a way that was truly not ok — not the way you talk to another human, especially one giving you business.Then when she’s “ready” for me to come in, instead of opening the door and telling me it’s ok to come in, she literally BANGS on the door from the INSIDE without saying a word. When I say bangs on the door, I am not even exaggerating — it was scary. It felt like she was trying to teach me a “lesson” on how to knock on a door.Truly one of the strangest and most uncomfortable experiences of my life. It was so off-putting I think I stayed for a little while and left. Might need therapy (and Jeri too).
April 24 · MariaMy second home. I've been training and teaching here for over 8 years, and the Kalvans are wonderful, welcoming people. All of LA's circus community passes through here at some point.
December 28 · KrazyKujoA true artistic space owned and operated by family circus film professionals. The only reason that it's not 5 stars is because I believe that the facilities should expand to full gym status by a few weight apparatus.
August 30 · Paradox PollackIf I could live here. I would. Amazing place and amazing people!
