The Social Work Podcast is an excellent resource for social workers. Jonathan Singer, Ph.D., LCSW, the host, covers a wide range of relevant topics. While the podcasts target social workers, much of the info is likely to be useful to anyone in the helping professions (such as psychology, nursing, psychiatry, counseling, and education).
The Social Work Podcast provides information on all things social work, including direct practice (both clinical and community organizing), research, policy, education... and everything in between. The purpose of the podcast is to present useful information in a user-friendly format. Although the intended audience is social workers, the information will be useful to anyone in a helping profession.
