In addition to the long-standing anomalies seen in the muon $g\ensuremath{-}2$, ${R}_{{K}^{(*)}}$, and ${R}_{{D}^{(*)}}$ observables by various independent experiments, the CDF Collaboration has found another significant one in the $W$-boson mass. These anomalies might be intertwined at a fundamental level and have a single new-physics explanation. In this paper, we present a simultaneous solution to these anomalies with two scalar leptoquarks of roughly equal mass---one a weak-singlet ${S}_{1}$ and the other a weak-triplet ${S}_{3}$---which mix through a Higgs portal. The solution has only a few new couplings and TeV-scale leptoquarks, making the solution testable at the LHC. We put a lower and upper bound on the leptoquark masses in this setup from the current LHC data and the assumption that all new couplings are within the perturbative limit.
