My husband had an aneurysm that was not the kind you wait and watch- it had to be fixed, and soon. We are currently living in Bangkok but decided to fly back to the US after he spoke with a top neurosurgeon (referred by a friend) who recommended he get it done in the US, and said if it was him with the aneurysm he would get it fixed with Dr. Diaz. We were so glad we chose him- it went perfectly and we are huge fans of his now! He is one of the top docs at Methodist and an aneurysm expert.
