Great advice/heads up!!
Sassybread: I changed my name on FB and had high controls so clients can't find me. I doubt that would look bad to POI. I would suspect they would prefer you being overly cautious than not - wouldn't phrase it as hiding something from PI. Another thing to consider is your email address - may be too late for that but I have been on hiring committees for several jobs and you couldn't imagine the strange emails people have that are a turn off!! Make it generic - use your cutesy names for friends if you must but not on resumes.
I currently have MA in Counseling Psych and LPC and there is a lot you can do with it. A lot of my cohort have private practices, some work in community centers, at risk schools, or university centers. Some work in research and do therapy with more clinical populations - including myself. One is even a psych consultant for a business college. I am applying to Clin Psych PhD programs because I want to be a professor in CO. There are not many universities in CO so it is very competitive to get teaching positions here - however have a friend in Chicago that has LCSW from U Mich and teaches at DePaul. It is not impossible to teach or do research with LPC so it comes down to time, money (loans), and creativity to get yourself in the job you want! Good luck!!
