    During COVID 19, I needed the best doctor because I was facing life or death. Medicare found Dr Sean Dalley... I have a loyal and devoted patient. Three doctors gave me less than 1 week to live . Drm Dalley extended my less than 1 week to 5 months shy of 6 years. He in my opinion is the best doctor in his field in Texas.
