Worked for pentec a robin kafman set up my 401k epon hancock

Wolves - I 'm not sure what you mean by "epon hancock" - do you mean that the 401(k) is administered by John Hancock? If so, you can contact John Hancock to find out the status of your account. You should be able to access your account here:

Or call them at the phone number given here:

If that's not what you meant, then I suggest you call the HR department at your former employer and ask how to access your 401(k) account information.
