We were sent to Mayo for a second opinion/confirmation on how to treat our 18yr old daughter. He was caring, listened to everything and was very thorough. He spoke to her but included us too. He gave us a care plan and our daughter a better quality of life (with meds since there is no cure). He and staff have answered many calls and emails when we had some issues. Can’t say enough about him and the staff. Our dr home will continue treatment but we are happy to know we can call and go see Dr Singer again if things get worse.
