I put in a number of years a sexual assault advocate (we helped people who had been sexually assaulted rather than advocate for abuse) and I have to take issue with one thing the DM attributed to the visit. Someone (and I think they meant the DOC) said that you can't exactly advertise that kind of service.
I disagree. You can and we did. Note that this was all pre-social media, but that choice would only make things easier to publicize. We were listed in the yellow pages, white pages and advocacy pages. We had close contact with the local schools and shelters and had flyers posted there. We were in contact with first responders (medical, police and fire), child advocacy agencies and local politicians who all knew who we were, what we did and how to reach us. The hospitals had our posters and would ask presenting patients if they would like us to be called in for them. We also were in contact with local OB-GYNs, Planned Parenthood and Pediatricians. We worked closely with the local press and had several events during the year for the press that spoke to who were were, what we did and how to contact us.
We covered two counties - spanning a state border. We had a 24/7 hotline, a daytime staffed office and would go out on calls 24 hours a day. We would attend hearings, doctor visits and other required "meetings" as requested by those we represented.
In general, working with survivors, an advocate's job is to enable survivors to do what they want, to "feel" control; to do what they feel is best for them; to let them know that they are valued and that their experience need not define them forever.
I loved that volunteer work. It was almost always very sad but so very needed and important.
And it can be advertised in ways that make it effective.
