  We construct a supersymmetric SO(10) model, where natural doublet-triplet
splitting implemented via the Dimopoulos-Wilczek mechanism is stable under the
addition of 126+\bar{126} Higgs superfields needed to generate the small
neutrino masses via the see-saw mechanism and where both the charged fermion
and neutrino masses arise from just one set of 10 and \bar{126} multiplets.
