My son came by ambulance after having a dislocated knee...BY AMBULANCE....and we sat in the waiting room for 7 HOURS....and still waiting. I understand they take people based severity but 7 HOURS AND STILL WAITING!!!! The x rays were read just waited and waited and waited for us to hear the results. Mind you they also had a head trauma that sat in the waiting room for 9 hours and walked out to go somewhere different....kid had a neck brace swollen face...and still waited. Absolutely ridiculous and this is the best hospital in our area??!!!
