Dr perry schall was my primary care physician at the Cleveland clinic. He knew exactly how to treat on symptoms of on coming asthma. I wasn’t sure about the coughing spasms I was having. He tried one treatment but didn’t give up on me and sent me directly to a pulmonologist who did diagnose asthma. Thanks to dr schall who was always there when I needed him. I was sorry to see him leave but I hope he is happy in Southern California
