What people have to say:

We’ve moved our PBM business a number of times searching for a solution to rising pharmacy benefit costs. We selected CHS because we viewed them as a partner in managing our pharmacy benefit program. Their fully transparent approach is real, our financial results validate it.”
– Director of Benefits, West Coast employer
We are very thankful for Costco’s RX program and all the saving it has afforded our company. With the specialty savings added it has allowed us once again to offer stellar benefits to our employees. We have always known that Costco is a very reputable business but once again you have proven without a doubt you are the best!  Costco RX delivered as promised.

– HR Manager, Midwest employer
This has been by far the easiest implementation from any of the other PBM’s we work with this year. Account/Implementation team very organized and proactive on communication with call notes. Looking forward to working with Costco Health Solutions.
