I saw someone else post about this doc, who is incredible! His name is Arash Horizon. Like the other post (and probably many folks on this board), I spent years trying to figure out what was wrong with my back, to no avail. But Dr. Horizon properly diagnosed me, which gave me peace of mind - the pain is *not* just "in my head".
Doc H and his nurse, Julie, and infusion nurse, Sharon, are all wonderful, caring people. He always calls back - something not to be taken for granted, especially in L.A. I highly recommend him!
