Can a beginner do PNF Stretches?

Hi guys i am quite new to stretching but i am quite flexible not in the hip area though. Im thinking of doing the stretches in this program http://phraktured.net/starting-stretching.html but instead of doing them passivley i will use the PNF Teqchnique and i will do them every other day. Is it okay for a beginner to start of with Pnf stretching right away? i have been doing static-passive stretching for a like a month.
