What job opportunities are there for retire Navy SEALs?

If you're interested in becoming a physical trainer, I'd recommend you research becoming a Tactical Strength and Conditioning Facilitator. They work specifically with emergency response, military, law enforcement.

Here's some information:

Now, if you're interested in physical therapy, go for it. (In theory you could be TSAC certified and licensed in physical therapy.) A Doctor of Physical Therapy program would be an additional 3 years after your bachelor's and a Physical therapist assistant program would be 1 year and significantly less expensive, also pay less, but may be a good supplement to what you'll receive from the military retirement system. (I'm assuming you already have the prerequisite courses completed.)

Here's information regarding becomming a PT/PTA and what to expect as far as income goes:

If you have further questions, let me know!

I think any job in outside security firm would fit perfectly for a Navy Seal. I know such states as Colorado and Oregon are in great need of security details due to the large amount of cash associated with the legal marijuana business.
