I traveled 5 hours to reach the Cleveland Clinic. I waited in registration for 2 hours, was kept waiting for an EKG and when I had a reaction to an anti arrhythmic medication upon returning home, called the dr.'s office and call was never answered. Overall, I don't think I will be returning as it felt like really 'big medicine' and I was treated like a number. The reception staff was wonderful however.
