What kind of wood and materials do you use for custom cabinets?

“Every First Class WoodWorks cabinet is built to one standard: furniture-grade plywood box construction (never particle board or melamine), solid hardwood face frames (Maple, White Oak, or Alder) joined with mortise-and-tenon construction, dovetail drawer boxes, and Blum undermount slides and soft-close hinges backed by a lifetime warranty.”
