May 15, 2020
I was in the intensive care unit at Winthrop Hospital. I was losing blood rapidly and in bad shape. I was praying for help. Dr. Grendell came dressed impeccably in a suit. An angel of the Lord sent him. He was very kind and explained to me what was to be done. He had his team with him. They saved my life. These are truly great people....and great doctors. THANK YOU ALL.
