We discuss the potential of Scalar-Tensor Theories (SSTs) of gravity to accommodate large hierarchies. In particular, we study the difference between the electroweak, Planck and vacuum energy scale and prove that the dynamical evolution of the conformal factor can account for them if it is effectively attracted toward its General Relativity limit.
