Need help sticking my footer to the bottom

I can’t for the life of me get my footer to stick to the bottom of the page. I’ve tried every method I can find on the web but nothing is working. It’s probably a simple fix but whatever it is I can’t figure it out. The site is here:

http://asa.bahijchancey.com/

It appears on the page bottom when you first arrive to the page, but if you scroll down it stays where it initially was rather than sticking to the bottom of the browser window.

Any help would be appreciated.
