Can a social worker help with trust funds?

Social workers aren't trained to manage funds, especially in a trust.

But first, are you referring to a revocable or irrevocable trust? If it's revocable and the maker of the trust has died, are you the Successor Trustee? If it's irrevocable, who is the Trustee?

No, Trust Funds need a Certified Financial Planner. But video tape that anyway and play it on youtube.
