“Dr. Weatherby, I bought your book many years ago and have been utilizing your optimal values to assess my patient’s lab results ever since. Thank you so much for your contribution to medical knowledge! It has been a tremendously important tool for improving the health of my patients as well as building my practice. Patients often came to me with their labs from another provider because I did such an in-depth job at reviewing them. They loved that I took the time to go over the labs and was able to give them an actionable plan to support their future health. I had an extremely busy successful practice in WA state and I utilized optimal lab value reviews for thousands of patients. Thank you again!”
