About MPI Metallurgical Processing Inc.

MPI Metallurgical Processing was incorporated by John and Vera Ritoli in 1957. With four expansions in its first twenty years, the company gained a reputation among area businesses as a successful "Mom & Pop" heat treating factory.

In 1977 Elena Ritoli, daughter of John and Vera, joined the organization. Elena worked through the various departments to gain hands-on heat treating experience before taking over as president of the company. Under her direction the facility has expanded in two stages to triple its size in 1988. MPI is the only heat treating company in the United States that is owned and operated by a woman, continuing the tradition with the third generation, Verneen Ritoli.
