About Us

Legacy and Avanti Self Storage

A Family Business

Providing you with friendly service and convenient self storage units

Our business began in 1978 when Cliff Sinyard built the first storage buildings and named them Avanti, inspired by his car, adding an “A‑” in front of the name to ensure the business appeared first in the phone book. Over the next two decades, additional buildings were added, expanding the operation until 1998, when the Coburn family purchased both locations on North Country Club Road and West Okmulgee.

In 2009, the Coburn family further expanded by acquiring Legacy Self Storage near the turnpike from the Campbell family. Today, in 2026, we remain a proud family‑owned business, with the second generation overseeing daily operations. While we no longer operate the West Okmulgee location, we continue to look ahead with plans to add new locations in the future.

When you’re ready to rent family-owned self storage in Muskogee, find the location nearest you and select your ideal unit online. We look forward to solving your storage needs!
