Building on a tradition of innovation, integrity, and imagination, CASTO has been a trailblazer in the real estate industry since 1926.

A growing portfolio and exceptional results.

In just the past several years, our team has more than doubled CASTO’s real estate holdings. Meanwhile, we have established and continue to maintain excellent relationships with financial institutions and institutional lenders to facilitate the financing of our real estate developments, construction, and acquisitions. CASTO is a survivor in a changing market and an innovator in a booming economy, and we have prepared for a very successful future for ourselves and our clients.

Providing expert and innovative solutions.

As a leader in real estate development, leasing, and property management, our aggressive growth plan has enabled us to broaden our real estate services to include construction management, tenant representation, and site selection and acquisition. Our solutions are a direct result of having some of the best people in the business coupled with a long-standing tradition in innovation, integrity and imagination.

Creating value.

For us, it’s more than just the bottom line. While we work hard to make sure that each project we undertake is a financial success, we strive to assure our projects are well planned, our associates have a good quality of life, our tenants are happy with the service they receive and that we work with the communities we enter to make both our project and their community better.


“CASTO’s foundation was built on serving its community and the company has not wavered from that mindset. Since joining the Columbus Chamber of Commerce in 1933, CASTO has supported and served the community in many ways including sponsoring events, providing guest speakers, and Don M. Casto, III served as the Chamber’s chair. The company has continuous growth and a community-centered mindset. We are proud of our partnership with CASTO.”
