My son was just diagnosed with MM here in Seoul (Severance) and so far we've been very pleased with the hospital and staff and I hope we find that they have a great deal of surgical experience.

I hope and pray that everything will go well for you and your family.

My daughter had 1st surgery at Severance Hospital for EDAS and 2nd surgery at Stanford Hospital for both direct and indirect last year.  She is doing wonderful.  And she just had 6 month follow up test in Stanford last month.  The result came out unbelievable.  It is like miracle to my family.  We thank God first and, Dr. Steinberg, and his staffs, Teresa, Jill all of members at Stanford Hospital.  Without them, we can't LIVE, LAUGH, LOVE.  

I can't express in a word how hard was my life when I found out about moyamoya.  
We  will pray for all moyamoya family.  
Stay strong!!!!

In Seoul?  I am interested in living in Korea, but need to make sure I have doctors that know about MM.  That is good to hear about doctors. Sorry about your son.  Good luck.
