Dr. Cash is a wonderful doctor. I wouldn't go to any other neurologist. I have been going to him for 18 years and he has always cared for me.

Dr Cash was an excellent listener regarding our adult autistic son. It was our first visit with him and he was very well versed in our son's medical history-especially to do with seizure history. We had questions about various medications and if they would be helpful. Dr Cash knew many of the medications we had questions about and if any of them would be helpful to our son.

Dr. Cash was absolutely incredible. He took a great amount of time to make sure that I was clear on explaining everything that I needed explained to me. He was extremely kind and fully, fully informed regarding my case. It was refreshing to encounter a physician like himself. I feel very fortunate that he is now my neurologist.

I was very pleased to hear that Dr. Cash was happy that I was having so few seizures and that by reducing or increasing my medications, I have had reduced seizures and they have continued to fall since then. And therefore, I am pleased with him and with the effectiveness of my medications. Thank you very much.
