Your Choice

Health concerns are a major source of lost happiness and lost joy in all of our lives. Finding a solution that is agreeable and enables you to get back to your life is important. Please appreciate that you always have the more invasive surgery and prescription medication available to you as a last resort. What many Traditional Medical Doctors may not share is, many times, once you begin that journey into medication and/or surgery, it alters your original body from the one that you were born with. Unfortunately, at that time, more conservative and natural treatments may no longer be viable. I encourage you to consider that before making any decisions about treatment for your health. As always I am here to help. 
Your Choice:
  • Continue doing the same thing and nothing changes or it may get worse


  • Try something different and get a different result that makes you happier and healthier.
The Choice is Yours
Please call Dr. Huntoon at 845-561-BACK (2225) to discuss your options or click on our E-Visit to do it via e-mail. 
Thank You for your consideration.
