What is my next step to try to enlist after being disqualified from MEPS?

Try the French Foreign Legion.

Do they have the second decline reason written down?

Did they ask for a consult? You are pretty much bound to your recruiter, you can ask for his oic or go to a different recruiter

It's not that your recruiter doesn't know what they are doing, it's simply that recruiters are not the approval authority. The MEPS doctor is the one that initially disqualified you, and it sounds like the documentation you submitted from Parkland, for whatever reason, didn't satisfy their requirement to prove the condition in question doesn't exist. The other explanation would be that the documentation was submitted by your recruiting station as a medical waiver and got denied by the Command Surgeon of whichever branch of service you were trying to enlist in. If that was the case, then there is nothing else you can do but attempt to enlist with a different branch, because changing your recruiter won't do a thing, and the MEPS doctor and Command Surgeon are THE approval authorities on medical conditions. There is no one else in the recruiter's chain of command that has authority to approve or disapprove anything medically related.
