I introduce a heavy neutrino sector below the electroweak scale with important consequences for neutrino masses and longstanding experimental anomalies. Contrary to typical seesaw extensions of the Standard Model, our heavy fermion sector is charged under a new hidden U(1)' symmetry, confined to a dark sector. We find that our dark particles can generate the correct neutrino masses at one-loop level, while remaining testable at current and future experiments. Most importantly, this is a minimal and self-consistent model for a dark neutrino sector, where a rich phenomenology arises with connections to MiniBooNE, the (g-2) of the muon and other experimental results.
