@malkani07- Good morning. Mayo Clinic is the top hospital in the US. You can't go wrong! MGH is rated the second-best. I'm glad that you are contacting other hospitals. Medical care in this country is phenomenally astronomically high.

I can tell that you love your father a lot! I wish you and your dad the best and I hope that he can come to the US and be treated as fast as possible. Please do keep us updated so that we can learn from your experience and perhaps help others who are in the same position.

If I can be of further assistance please let me know. I may not be able to offer the technical aspects of coming to America but I and others on Mayo Connect can offer support and comfort to your whole family. Connect is a worldwide on-line community and we have wonderful, warm people from all over the world helping others. We also have a Caregivers group that your mom or siblings might want to look at as well as yourself.
