Full Site on Mobile Devices

Hi there, I am trying to get my full site to be visible on all devices including mobile devices. I have tried disabling responsive design in the Theme Options. That doesn't do anything. I have tried activating and deactivating the mobile theme with jetpack. That doesn't do anything. Even when the jetpack mobile is activated and I tap on "View Full Site" it just takes me back to the single column responsive design site. What am I doing wrong on this? Can you help me fix this so my site looks the same on all devices? My site is teachmeios.com Thanks!
