MWD is a good outfit. I have not heard that they offer the SWR course to the public. Rocky Mountain Adventures has traditionally hosted a SWR course every Memorial weekend. By Host I mean that they bring in a Nationally recognized instructor, it may be another company, and the guest company/teachers run the class out of RMA's base. I know a lot of people who have taken the Course at RMA and they speak highly of it.
Ben Costello is the River and Operations Manager at MWD and last I heard he was a year 'round full time employee. Give them a call, or call RMA and they can set you up with the correct beta.
The Paddler's Pub at MWD is the closest bar to RMA, so you might wind up there anyway, at least for a few moments.
Best of luck,
