The quality of VHI exercise collections is one of the main reasons for our success. VHI has a rigorous author recruitment process. Authors of VHI collections must demonstrate that they have the experience and necessary knowledge to develop a specific exercise collection.

Recognized authorities in the field have developed or are developing VHI exercise collections. VHI has been honored to have people such as Carole Lewis, PT, CCS, Ph.D.; Gary Gray, PT; Sara M. Meeks, PT, MS, GCS; Kim Christensen, DC; Jonathan Urla, MFA; and Bonnie Berk, RN, to name a few, contribute to the content of the VHI collections.
