A composite model of quarks and bosons is proposed in which a spin 1/2 isospin doublet psi is the basic building block of quarks and bosons in the standard model. The psi has two components v and w with charges Q = 1/3e and Q = 0, respectively, that combine to form the three generations of colored quark flavors. A strong force described by a triplet of massless gluons binds the constituents called geminis. The confining constituent non-Abelian SU(2)(C) field theory is called constituent dynamics with a confining energy scale Lambda(CD). The constituent dynamics condensate <(v) over barv + (w) over barw > not equal 0 spontaneously breaks the electroweak symmetry SU(2)(L) x U(1)(Y) -> U(1)(EM) and a triplet of Nambu-Goldstone bosons make the gauge bosons W-+/- and Z(0) massive, while retaining a massless photon. A global custodial SU(2)(L) x SU(2)(R) symmetry guarantees that the symmetry breaking in the weak interaction sector agrees with electroweak data. The non-Abelian SU(2)(C) color dynamics satisfies asymptotic freedom, which resolves the gauge and Higgs mass hierarchy problems and makes the model ultraviolet complete. The composite constituent dynamics model can realize a SU(3)(C) x SU(2)(L) x U(1)(Y) electroweak and strong interaction model that satisfies the naturalness principle. The three generations of colorless quarks alpha and beta with charges Q = +1e and Q = 0, respectively, which are predicted to exist in the composite model can form bound states which can be identified with the spectrum of exotic mesons.
