This work is a contribution to the area of Strict Quantization (in the sense
of Rieffel) in the presence of curvature and non-Abelian group actions. More
precisely, we use geometry to obtain explicit oscillatory integral formulae for
strongly invariant strict deformation quantizations of a class of solvable
symplectic symmetric spaces. Each of these quantizations gives rise to a field
of (pre)-C*-algebras whose fibers are function algebras which are closed under
the deformed product. The symmetry group of the symmetric space acts on each
fiber by C*-algebra automorphisms.
