How to turn off the gps and location services on my iphone 5?

I have a verizon iphone 5, my dad says he can locate me through my phone, I turned location services off, is he still able to try and locate me any possible way and is there anything I can do to turn it off?

If you have the app find my iphone delete it. Other then that you should be fine.

Turn the location service off… Then to be safe you can turn on airplane mode
