S.O.S!!! Susan, WHERE ARE YOU?!

I want to ask Susan so many questions. She is a great documentary filmmaker who gave a class in my program during the Spring. I think she is the only filmmaker I have had as a professor, and now that I'm going through this project I want to ask her so many things.
How is that documentary filmmakers hire editors? I think I could never do that. I mean, that's to give someone else SO much power over your story! Does Susan edit her pieces? Does she hire someone, build a strong relationship, and then that person is always the editor for her movies?
I think I would like to be a documentary filmmaker who gets her hands dirty and just edits her own pieces. At least, I would like to be the one selecting the clips and, of course, building the structure of the piece. I can hire someone to do the color correction (oh,yeah!!!!!) but not for the editing itself. But it's pretty obvious that there is something that I'm missing here, since you can see editors other than the director in the credits of each and every respectable doc.
I think I'll try to attend one of Susan classes before I leave the country, since she's running again the class I took. I mean, this question is just the (how do they say it here?) top/tip/point of the iceberg. I need her advice on the relationship you establish with your subject, and she is THE ONE to ask about this, because she worked on the same subject for 8 years. She is a really warm, nice, sensitive person and I'm pretty sure she gets really attached to her subjects. Susan, come and SAVE FROM MYSELF!
