We use the Landau-Ginzburg formulation of the Kazama-Suzuki series of exactly solvable models to compute the spectrum of all N=2 supersymmetric twisted G/H Landau-Ginzburg compactifications for hermitian symmetric spaces G/H. We show that the Landau-Ginzburg potentials associated to Kazama-Suzuki models all belong to the class of singularities we have constructed in previous work with P. Candelas.
