  One simple way to lower the scale of the seesaw mechanism that generates
neutrino masses is to attribute part of their smallness to a suppressed vacuum
expectation value of a second Higgs doublet as in the neutrinophilic 2HDM or in
the type IB seesaw model. On that structure we add one charged singlet scalar
to induce a chirally enhanced contribution to $(g-2)_\mu$ with the same
righthanded neutrinos of the seesaw. We discuss the interplay of generating the
necessary contribution to the latter with lepton flavor violation which is also
necessarily brought to low scale. We show that it is possible to explain
$(g-2)_\mu$ even for heavy neutrino masses of order of a few TeV.
