WHO WE ARE
In May of 2016 two couples, Natalie & David Bohannan and Jessica and Shane Irgens, took over Greenwood Physical Therapy clinic. Together they formed a new business--BIG Physical Therapy: derived as an acronym from their surnames, Bohannan-Irgens-Group. The business proved successful and, within a year, they expanded and opened a clinic in nearby Fort Smith. The business continued successful growth and in 2021 the business partners expanded their operation again by opening a third clinic in Barling.
