Board of Directors

The vision of the founder of the Association for Vascular Access (AVA), Suzanne Herbst, was to create a multidisciplinary organization. To this end, our membership is populated by doctors, nurses, respiratory therapists, researchers, educators, NPs, PAs, patients, executives, manufacturers and others.

The Board of Directors (BoD) of AVA, historically and presently, resembles the demographic listed above.  The individuals on the AVA board are all leaders in their respective fields and volunteer their time for this organization.  These volunteer leaders often work as consultants and Key Opinion Leaders (KOL) in the Vascular Access community.  We welcome these relationships, but at the same time recognize the inherent perception of bias perceived as coming from within the BoD.

Each AVA employee and BoD member is required to sign and abide by The AVA Conflict of Interest Policy which directs actions of each individual when a conflict arises. 

Each presentation from a member of our BoD or employee must have this statement along with appropriate Disclosure(s):

"I am currently an AVA Board member.  This presentation does not reflect the position of AVA unless specifically cited."

If you have any questions please feel free to contact Tonya Hutchison, AVA COO at or at 801-792-9079 ext. 102.
