IRW, one of the largest post-acute rehab providers in the region, currently employs more than 120 physical, occupational and speech therapists, providing services in skilled nursing facilities (SNFs), home health, assisted living, independent living and outpatient settings in the Omaha and Lincoln metro areas. Approximately one-third of these therapists have advanced credentials in their field – many with doctorate level degrees – and IRW employs more therapists board-certified in geriatrics than any organization in the region. In recent years, team members have been published in peer-reviewed rehab journals and have presented our work at national conferences.

With an actual focus on innovation, IRW collaborates with Creighton University School of Pharmacy and Health Professions for both the Occupational Therapy Fellowship Program in Gerontology and the Physical Therapy Geriatric Residency. The Physical Therapy Residency Program is one of only 16 programs in the country and the only program in Nebraska or Iowa, while The Occupational Therapy Fellowship Program is the very first program of its kind in the country.


Each leader of Innovate Rehab & Wellness (IRW) has decades of experience in physical therapy and rehabilitation services. Together they lead a team of more than 100 physical, occupational and speech therapists. Their strategic vision for serving aging adults has led to the creation of several unique programs and professional relationships that enhance the services that IRW offers.
