I have seen MSSWs, LCSW, PhD (who started out as MSSW), and LPC (Licensed Professional Counselor). The T I saw prior to my current one started out with his Master's in Social Work, then went on to receive his PhD when he was in his early 50's. Even while an MSSW, he taught mental health assessment and diagnosis to social work students and other professionals. The T I see now is LCSW. My current Pdoc started out as a pharmacist, then went to school and has his D.O. degree (doctor of osteopathy) which qualifies him to practice psychiatry. But he has blocked out extra time for me this past year to do a bit of therapy because he knew I was losing my former T. Most psychiatrists have an M.D. The LPC I saw was an excellent therapist, and worked quite well with me regarding PTSD and childhood abuse issues, plus DID. So, each "specialty" is not as narrow as the training implies.
