Welcome to American Family Chiropractic


Dr. Kosbau has retired as of September 15, 2021. 

After almost 40 years, I am retiring from practice.  For me, Marie, and Judy this marks the end of careers in which we have devoted our lives, energy, and precious time.  Our emotions run deep. Caring for you has been our privilege.  

I will miss each of you.  Now, I must start a new adventure.  

You should have received a letter or e-mail from me about my retirement along with referral doctors.  If not, I have listed Chiropractic doctors below.  I truly hope that you will continue your care as it can make life so much better. I wish each of you a healthy and happy future.

Reviews By Our Satisfied Patients

  • "I had lower back pain that radiated down my left leg to my foot, and I could not stand for very long. After treating with Dr. Kosbau, my back feels better than it has ever felt in my adult life."
    Willie J. / Sacramento, CA
  • "I had stiffness in my lower back, it was very hard to get up and sit down, and being in one position was very painful. I could not move my neck sideways, and I was having a lot of headaches. After starting treatment with Dr. Kosbau, my condition improved so much and so quickly that I can do everything and anything so easily without pain or discomfort."
    Anita M.
  • "I suffered from severe headaches for 15 years. Every one was just a little worse then the one before. The last 6 of those years, I lived everyday of my life with a headache of one degree or another. I have not had another bad headache since the first adjustment."
    Mary Ann
  • "After a fall skiing, I could barely walk and had a tearing sensation in my lower back. Within two days after starting treatment with Dr. Kosbau I was walking normally."
    Carol K.
  • "I had tendinitis in my right shoulder, which caused severe pain and numbness and limited motion in my lower arm. After starting treatment with Dr. Kosbau, my shoulder area is completely healed. My spine is straighter and a leg that has always been shorter is now almost the same length as the other."
    Jean P.
  • "My back slipped out during spring planting, and I could hardly move. Dr. Kosbau examined me and started a treatment program. I'm feeling back to normal. What a great feeling to be able to continue normal activities without pain."
    Vivia W.
  • "I had lower back and arm pain for 5 years. After only 4 treatments, I really felt so much better, like a new woman. I can walk without pain."
    Hazel D.
  • "I had extreme pain in my neck,and back, I could hardly sit, stand or breath, and I suffered with headaches and muscle spasms. Since starting treatment, I am able to sit without my back getting tired for long periods of time. I am also able to enjoy sports with my kids without hurting. Dr. John is an extremely thorough and careful doctor. He is very concerned about his patients and treats them like family."
