    YOU ARE NOW WARNED, BEWARE! I am a retired doctorate level medical professional and I am my medical…read moremanager dealing with several chronic illnesses and conditions. RELUCTANTLY, I NEED TO WARN THE PUBLIC ABOUT THIS DOCTOR. Read his negative reviews and especially his history. He was disciplined by the medical board and put on 5 years probation a very heavy penalty. At his penalty hearing. He said that his prior mistake had made him a better doctor. I STRONGLY DISAGREE. I saw him for one month and he made very serious malpractice level mistakes in my care. He prescribed and pushed antibiotics for a virus.. That's why we have MRSA... because of the inappropriate over prescription of antibiotics. He recommended even pushed for me to increase a thyroid medication. When it turns out I didn't need it in the first place. He had refused to do the thyroid test that would have showed him. I didn't need it. He completely mismanaged my care for daily disabling long covid headaches. And don't get me started about his office manager. She is abrupt, arrogant and rude, less than competent, and like the incompetent doctor she works for. She thinks she knows better for the patient than the patient knows.

    I filed a complaint against Dr. Kingsbury with the Medical Board of California after my father's…read moredeath. Unfortunately, the Board decided not to discipline him, but instead, said he would be sent an "educational letter" to encourage him to provide the highest level of professional care. I warned the Medical Board that if they did not discipline him, other patients would be harmed. They didn't listen. However, a few years later, Kingsbury was caught up in what was called the Medical Board's Death Certificate Project, an investigation of people who had died from prescription overdoses. According to Board documents, Kingsbury prescribed more than 400 vicodin pills to a patient in a six week period, which resulted in an overdose. I attended a Medical Board hearing in which Kingsbury tried to blame the patient for being manipulative. That argument apparently didn't work. In March of 2020, Kingsbury was given 35 months probation after being found responsible for the patient's death. Here is the Medical Board document detailing Kingsbury's probation, which will remain posted on the Board's website under his profile page: https://www2.mbc.ca.gov/BreezePDL/document.aspx?path=%5cDIDOCS%5c20200221%5cDMRAAAHL14%5c&did=AAAHL200221224800657.DID
