    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.

    He’s a fantastic Dr! I’ve been with him for many many years & have a lot of complexmedical conditions . Making me a very hard case. Have 2 conditions that are not very well known or understood by most Doctors. He really listens and has learned & studied about my conditions and does everything in his power to help me. I am learning about them as well. We are learning together. He also does his best to help his patients & really cares about them. If he can’t help you in a particular area then he will find a doctor/specialist that can’t help you. He is thorough.He does regular labs on me to make sure all is good. He jumps through all the hoops the insurance puts out when I need blood work done or certain Imaging . Great bedside matter and that’s lost in today’s society. He make sure that you understands him & the next steps needed. He canceled you in the decision-making about yourself. He goes over and above for all of his patients.
