I have known Dr Bayer for 17 years, he saved my life 17 years ago and he leads every health issue that is the result of saving my life. He said years ago, itâ€™s usually not the cancer that kills you but all the issues that come up as a result of the horrific chemo side effects. Itâ€™s a testament to Dr Bayer how dedicated and smart he is, he has lead me through all the challenges and I am still standing thanks to him and his great team of nurses, PAâ€™s, MTâ€™s and secretaryâ€™s that make sure everything is done behind the scenes.
