    How was your appointment with Dr. Seymour?

    Jan 13, 2023
    Beyond excellent, Thanks to God first and Dr. Seymor I still have my wonderful wife with me. We went to seem him for first time in 2013, my wife had breast cancer and he made us at ease. He was right to the point and didn't try to sugar code it and we appreciated his honesty. We flight back from Colombia every 6 month for the las 10 years, and she still in remission. We are back in Houston and sadly find out he no longer with Millenium oncology. If any body knows were he work now please let us know.
