Las Vegas, NV |
Good doc but impossible to reach by phone.
in Las Vegas, NV |
He is the best neurologist in Las Vegas. He is incredibly kind & empathetic. He took the time to thoroughly test me & find a diagnosis. I had been to many doctors & had run across so many who rushed through the tests & didn't really listen to me. Dr. Diaz really drills down & asks a lot of questions! I was so shocked by his caring manner & intensive testing. I had almost given up on finding help until I met him. You may have a long wait in the waiting room becasue he does this for everyone.

Dr Diaz was suggested to me after 3 years of seeking a solution and reaching a point where i was never going to see another Dr..His warmth and compassion instantly made me comfortable, He listened and actually heard me, He was the one who discovered that I had a malignant brain tumor and had been misdiagnosed for years, referred me to a wonderful surgeon .. He is truly an amazing human being who happens to be a Dr..I now am 21 years away from that diagnoses still grateful to Dr Diaz :)!!

Kept us waiting more than an hour. We were told this is the norm, that he runs late. Terrible. No doctor is worth this.

I have a rare autoimmune condition and he is very knowledgeable about it. He explains things so I can understand what I need to do to manage my illness. He genuinely cares about his patients. I give him the highest ratings.

Waited over an hour in a tiny waiting room with a TV running annoying programs and sound!

Dr. Diaz is great. He listens to your concerns and does not like to sugar coat anything. He does not give up until he has an answer for you. I wish I had found him a long time ago.

The wait time can be a little long at times. However, this is because Dr. Diaz always treats his patients with respect and spends as much time as needed with them. A lot of doctors seem to treat you like they're working on an assembly line; in-and-out as fast as possible. You won't see that with Dr. Diaz and his staff. I've been blessed to find some good doctors here in the Las Vegas area. He's among the best and his staff is great too! BTW: I highly recommend him to everyone!

He makes you feel relaxed which is not easy when you are getting needles in the eye area. Over 10 times done and never a problem feeling like he did his best and I would now function normally. I'm upset my new insurance does not cover Dr. Diaz. His office staff is fantastic and always shows concern for me. I sure miss Dr. Diaz.
in North Las Vegas, NV |
Called office to make an appt. and let them know that I had the referral and could email it, but I needed an appt. ASAP. Was told by Sergio he did not have email. I finally went to the office to make my appointment. Unable to get an appointment with Dr. Diaz until late September, it's 6/1. Been dealing with severe memory problems for months, had to go thru appropriate channels before getting referral. I am sure he is GREAT, however, I am in need of help now, he is not in need of patients.

I have been going to Dr. Diaz for 20 years. In between, I have retired and moved to several states and have gotten Botox injections for my Dystonia/Torticollis from other Neurologists, none of which had the same resolve of symptoms as Dr. Diaz did. I then flew from other states to be treated by Dr. Diaz. I totally find he is the best and will not be treated by any other Neurologist. Also he is very kind, caring, kind and compassionate.
in Las Vegas, NV |
It's not the doctor its the appointment personnel. Slow responses to messages left on telephone. They say they answer 300-400 calls @ day and that is why they can't get back to me in a timely basis. I asked that they email me information on my doctors visit and they said they don't email and that I would have to go to their office to pick up my results. Customer service needs to be improved to include timely responses and the ability to forward medical reports to patients via email.
