My son and I joined to share an activity and learn together. After consistent failure of the instructors to hold anyone to any level of skill to progress (at the Lone Tree location), I questioned our desire to continue. After pre-paying over $1500 to avoid reported price hikes, the business changed belt progressions, effectively making the membership twice as expensive, for a path to black belt that would take twice as long. After dozens of communications via phone, email, offers to meet, and more with multiple members of the business including the owner, still no response. I believe this location is now closed, and I have no doubt it was due to these issues I'm describing here, but beware; the same owner still runs ATA Karate Denver in Highlands Ranch, located at 205 W County Line Road, Littleton, CO 80129. Join at your own risk of poor instruction, non-existent customer service, and deceptive marketing and billing practices. read more
