Just search on IMSC. Their next conference is, I think, in the autumn in Phoenix. I have been to 10 or more and always learned something that helped me make more $$$. And, quickly earn enough more to pay for the expedience of the conference and travel. Also, made a ton of priceless friendships with shoppers, schedulers, MSC company owners and project managers. MSPA also holds conferences, but I have not done any of those. A couple of forum members have and they will probably chime in on this thread.
