  We built an extended 2HDM theory with a spontaneously broken $U(1) _{X}$
global symmetry, where the tree level Universal Seesaw Mechanism generates the
mass hierarchy of the Standard Model charged fermions and the Zee-Babu
mechanism produces tiny active neutrino masses. The third family of SM charged
fermions gets tree level masses from Yukawa interactions involving the Higgs
doublets $H_1$ (for the top quark) and $H_2$ (for the bottom quark and tau
lepton). The model under consideration is consistent with SM fermion masses and
mixings, with the muon and electron $g-2$ anomalies and successfully
accommodates the constraints arising from charged lepton flavor violation and
meson oscillations. The proposed model predicts rates for charged lepton flavor
violating decays within the reach of forthcoming experiments.
