Dr. Katznelson is obviously a highly intelligent man with a passion for his field of neurology. He has a surprisingly good rapport (don't tell him I said so) with his patients. (Neurologists are not necessarily famous for that.) I happen to know this because after I began seeing him I found out several friends use him too and are pleased with demeanor as well as his professional expertise.

Dr Katznelson first diagnosed my case of myasthenia gravis in 2011. After significant treatment, I was able to return to a normal lifestyle. He has been treating me ever since. My condition recently deteriorated, and he recommended that I have another significant treatment. I completed the treatment at Northwestern Memorial's neurology department three weeks ago. The results have been remarkable, and I have been able to return to a normal lifestyle. Dr Katznelson will continue to treat me in the future.
