'Cheer Perfection' Star -- Coaching Kids Again After Drug Arrest


The cheerleading coach from "Cheer Perfection" who got busted for marijuana a month ago ... is back in the gym coaching young kids again ... and parents are pissed.

TMZ broke the story ... Ronald Dunlap -- co-owner of the gym featured on the TLC reality show --  was busted on January 15 with another coach for possession of pot and drug paraphernalia.

Now parents at the gym tell us Dunlap was back leading classes at Cheer Time Revolution last week. We're told many parents are angry because they never got a heads up he was coming back.

Dunlap's wife and CTR co-owner ... Alisha had suspended him indefinitely due to a zero tolerance drug policy. Alisha now tells us her husband was only back temporarily because they were "short-staffed" one day. 

She added CTR is in the process of drug testing all staff members -- and once Dunlap tests clean ... he'll be back permanently.
