There was a lot of speculation from different people about everything so I figured that clearing it up might help and yes all 3 still exist, NE is just very small now.
Basically it it all started out with Premier and All Heat (which was my gym). NE was a gym farther south that ended up buying out a program in Roc that I can't remember the name of. Heather left the old gym because she was caught "mishandling" funds but girls worshiped her so the new gym was successful. A few years later, a couple of the Northeast coaches/partial owner left NE and took over Premier and made them Core. Some athletes left and went there but it stayed pretty even. Fast forward to 2010-2011 season. Core, NE and All Heat were all fighting each other for athletes for Level 5 teams. At the start of the season, Heather came to our owner and asked to combine our Level 6 teams (we both had like 12 people without crossovers) but in the end the other NE owners wanted nothing to do with it. More rumors surfaced, including her mishandling money and other things, so she left NE about halfway through the season... taking with her about half of their Level 5 team. Some of the girls went to Core to cheer on their Level 5 and a few came to All Heat but Heather really didn't have a say in our gym at the time and to be completely honest, no one really wanted her. She had talked down on our gym before and had tried to recruit us via Facebook, etc. Heather began to play a larger part towards the end of the season, with us letting her do privates and help when needed. A week before we were to head to U.S. Finals in VA Beach, the announcement was made that FAME would be "assisting us" and we would be changing our name. Our owner still technically owned the gym but Heather now owned part and so did Fame. It became an issue as try outs were set to start because Core kids were threatening kids saying "we're the original black and red" and all that jazz. A few kids switched gyms here and there but not as many as people suspected. NE actually took their biggest hit when Heather left to begin with. All in all, Fame provided the money that our smaller gym needed to keep from going under. Also there was another really small, one team gym in Rochester... Silver Bullets but they are now part of Core if anyone was curious.
To be completely honest, Fame lost a lot of kids when they became Fame... because a lot of the kids who had been there forever, didn't want Heather and wanted a more family atmosphere. I was one of them. I never actually cheered a season for Fame although the owner was my high school coach too and I cheered for her for 10 years so we're very close.
