Over the course of nearly 35 years, RIZZO has grown from a small, 6-person office to a large corporate headquarters with regional (United States) and international representation. Our qualified staff of technical and design professionals, most with advanced engineering or geoscience degrees and corresponding professional licenses, collectively work to support projects coordinated from our corporate headquarters, but also service clients and markets specific to our regional representatives and our key collaborators.
RIZZO International, Inc. began business on November 1, 2017, following an ownership transition of RIZZO Associates, Inc. from original founder and primary shareholder, Dr. Paul C. Rizzo, to the new leadership and direction of RIZZO International, Inc. president, Ms. Rachelle Rizzo, MBA.
Ms. Rizzo brings over 25 years of leadership experience and a strong background in engineering consulting to RIZZO International, Inc. with her previous management leadership role in RIZZO Associates, Inc. Ms. Rizzo, along with her corporate leadership team, has set the course and direction for RIZZO International, Inc. to continue great engineering traditions while focusing on innovation and technological advances of today and the near future.
The team of world renowned engineers working for RIZZO Associates, along with the administrative staff, transitioned directly to RIZZO International. RIZZO Associates, Inc., our predecessor firm, was founded by Dr. Rizzo in 1984.
Women's Business Enterprise Certification
With direct ownership of RIZZO International, Inc. by Ms. Rachelle Rizzo and as part of our business transition from RIZZO Associates, Inc., our firm became certified as a Women’s Business Enterprise (WBE) by the Women’s Business Enterprise National Council, the nation’s largest third-party certifier of businesses owned and operated by women.
