A new measurement of the muon g-2 has been recently reported by the Fermilab Muon g-2 collaboration and shows a 4.2σ departure from the Standard Model (SM) prediction. At the same time, the origin of the large hierarchies in the SM fermion masses, as well as the hierarchical structure of the CKM quark mixing matrix, constitute a long-standing open question in particle physics: the so-called SM flavor puzzle. One dynamical approach to this puzzle is to couple the first two generations exclusively to a new subleading source of electroweak symmetry breaking, in the form of a second Higgs doublet. In this talk, we will discuss a SUSY realization of this mechanism and its impact on the muon g-2 anomaly. Contrary to the most studied SUSY models, in this framework sleptons with masses in the multi-TeV range can comfortably explain the anomaly. We will also discuss additional phenomenological aspects of the model, including its effects on tau flavor changing decays.
