About

Bio

Hello, everyone my name is Dr. Mark Weisberg and I am from a small city in the lower Rio Grande Valley of Texas called Brownsville. I am an internal medicine doctor working for a hospital currently though would love to expand and help everyone that has access to the internet with no waiting rooms or expensive hospital stays that can be prevented by treating early. This is the key to medicine. "An ounce of prevention is worth a pound of cure"
