My Mother has had horrible interactions with Dr. Katz as well. I was shocked at how he treated her as a patient and his lack of medical treatment could have killed her. I cannot go into details because I suggested that she file a complaint with the Medical Board. Just know that you are not the only one with complaints about Dr. Katz. The Dr. works for you, the patient. Unfortunately, many Drs. are megalomaniacs. Be your own advocate and if something isn’t right, leave and find a good Dr.
