They will accept all the major certifications in the industry. I also know that they offer their own certification process, especially if you want to climb though their different tier levels. Once you apply and you meet their criteria, you will be contacted by one of their recruiters where you will be able to ask them any questions you want. They will also provide you with the requirements of the position you are applying for. You could also try to call them and talk to one of their fitness managers to make sure you have what they need before starting the application process. I hope this helps.
