Membership Information and Fee

Our membership fee helps to provide education and CEU's to those members who are maintaining different certifications. We will also be partnering with AHRMM to deliver specific CMRP training.  Your membership fee will include virtual events and in-person meetings.  Non-Members will pay $65 for the day long in person session(s) to help cover cost of location and food.  (4 CEUs)

Our partnership with WAHRMM (Western AHRMM) helps to reduce the costs of maintaining our own individual website.  As a non-profit there are other costs associated with maintaining that status which includes insurance and corporation costs.  Your membership fee also helps cover those types of expenses as well as our educational offerings. 

We will charge a different amount for our vendor partners (individual membership) as well as offer sponsorship programs.  If you have questions on our programs; please email

Education Chair

Ed Gerhauser, CMRP is the Director of Supply Chain for Banner Baywood and Heart Hospital Campus. Started my career in the fire service and medivac field and I always enjoyed managing supplies and purchasing needs as a added duty.  When the family came along, I needed some stability in schedules, so the natural progression was moving into the hospital setting.  I have a passion for developing supply chain professionals and firmly believe that we are stronger as a team when we grow as a community. My wife and I have three very active girls, and several animals but not quite a farm. Our family enjoys outdoor activities in the great weather, and attending the many volleyball, and dance events that come with the girl’s activities.  We have also become a hub for friends and family that want to thaw out in the winter so enjoy spending lots of time entertaining guests. We haven’t desired to see snow again yet so we only go north in the summer both in Arizona and Alaska.
