I totally agree with Brett Stanaker, I believe it is the Harvard of designations in our field. I will be getting this designation by the end of this year.
I'm very proud to have earned my CRS designation and I would highly recommend it. Just the fact that it must be earned only by proven experience and further education says a lot. It's one of the highest designations you can get and only 3% of REALTORS nationwide have earned it, so it sets you apart from other agents when giving value to your clients.
