@Grivusangel: Check your local newspaper for events offered by various public health facilities in your town. Look for things offered by mental health associations, special support group meetings and that kind of thing. Call assisted living facilities to see what they're offering.
Most of these events will mention if CEUs are available, and who can claim them. If social work is not listed, and you'd like to attend the seminar, workshop, etc., then by all means call the facility offering the program and ask if social worker CEUs are available. It may be the event coordinator never thought about offering the credits. The worse they can say is no.
