Philadelphia OSO

The Philadelphia OSO is located at 900 Market St., Ste 313 (view on Google Maps). You can call the office at 215-238-0400/0477. As far as I know, the Philadelphia OSO does not have a website.

After finding your local Marine OSO, learn how to apply for commissioning or prepare yourself physically for Marine OCS.

If any of the above information is incorrect, please contact me.
