Dr. Oscar Grandas performed a herograft on my right arm. I am 90, female, and 11 years if dialysis. Professional, skilled, compassionate, and thorough are only a few if the words to describe this gifted vascular surgeon. He has allowed me to continue my dialysis and live my life. He is a gift to any one needing a skilled vascular surgeon! He is simply the best. U.T. is so very fortunate to have his services. Thank you Dr. Grandas.
