In 1979, two Respiratory Therapists noticed a distinct lack of respiratory services in Southeast Texas. So later that same year, they opened Walson, Inc. to provide this area with superior respiratory services. In 1983, Walson, Inc. expanded to provide a full line of Durable Medical Equipment. 1985 brought another expansion as Walson, Inc. opened a branch office in Lake Charles, Louisiana to provide Southwest Louisiana with the same quality services.

Walson Inc. was the first DME Company to bring the Oxygen Concentrator to this area. This vital need was recognized by Walson Inc., so the necessary drive and initiation soon followed as the company felt obligated to assist the respiratory care of patients in this area. Walson Inc. is accredited in both DME and Clinical Respiratory Care, and both locations serve a 90-mile radius.
