I'm not sure of what I can add to the discussion regarding LCSW.
Social workers can be a college graduates. Many social workers get a start in child protective services, an entry level job. Because the job is pretty intense, a lot don't make it and bail out after a year or so. Some go on to take administrative jobs with a bit more experience and others go on to grad school.
The LCSW is, to my knowledge, a masters' level that requires certification plus experience and additional training. In addition, LCSWs are required to get continuing education credits on a yearly basis.
It's no guarantee that a LCSW is any more competent than a masters' level psychologist or LPC (licensed professional counselor). Best to interview the therapist using the "Consumer's Guide to Therapist Shopping". Be aware that the therapist who is too busy to answer your questions is probably someone who may be very competent in treatment but is not maybe a good fit for you.
Hope this answers your questions.
