Width Display Problem on Desktop

Hi, I am helping a friend of mine design a website. I have no real knowledge of coding outside of a blog I did a while back. Anyway, the website is greattalktherapy.com and I am having a problem with the "Comfort, Community and Change" section not displaying properly on a desktop device. The first problem is that the "Comfort" section appears to be cut off. The second is that the "Change" section isn't displaying as a proper third column like it used to. I hope that I can find some assistance here. Thank you for your time.
