Judgement Question - Contact/Legal

[Daniella Steinberg]

Hi - 

I have a former tenant who was behind on rent, and then vacated the house without notice. I now have a judgement to reclaim some of the lost $, but she has been totally silent and has not replied to any communication, nor shown up in court. 

This property is managed by a property manager, is it appropriate for the PM to call/visit her place of employment, call/email her boss etc, in order to try to get in touch? I would hate to have to go to a collections agency.  How do I find out what kind of contact is appropriate, before it is too aggressive? Is it best to just contact lawyer (for the specific state)?

Thank you
