CME also played an important role in deciding to go with the lifetime membership. I think it is a great value and good product...Early in my career I found your radiology modules incredibly valuable and greatly improved me as a clinician...Customer service could not be better.

My background with Challenger goes back to 2006, when I used the Family Medicine product to re-certify for the American Board of Family Medicine. By using the Challenger product, I scored in the 96th percentile. That satisfying experience led me to become both a lifetime subscriber and an investor in the company.

I am so happy that I bought the lifetime subscription. It was definitely the best expenditure for CME I have ever made. I pass my LLSAs easily each year and feel I learn the material. I used my CLS online for my 2001 boards and again in 2011. I don't know what I would have done it without your expert assistance. I'm sure I would spend far more money!

I just wanted you to know how much I am enjoying receiving and using my Challenger programs. I now realize that Challenger is far better than I ever knew. The amount of material that is covered is amazing. I'm thrilled to have taken the chance on the Lifetime Subscription.

So, I used my CME budget to buy the lifetime subscription in 2005. Since then I've prepared for and passed my boards, completed all my MOC and state reqs and I haven't spent a dime to date on any of it. I know of no other product like this. Still getting new products regularly and they're always free. Best investment for an physician's longterm education and career needs.
