OMG, I love Dr G. This man is the schizzle, very knowledgeable and compassionate - saved my husbands life, and although it required amputation of his leg, Dr. G did an absolutely amazing job of it. Nobody expect my husband to recover from his infection and necrotic foot but Dr. G proved us all wrong and we own him so much because of it. Thank you Dr. G for all you do.
