Above is a link to a Naturopath I saw a year or two ago. His prices (in our area) tend to be on the higher side, but he is EXTREMELY knowledgable. He told me in our first visit "I can't cure cancer". That said, he has extensive knowledge about the body, the disease and how to best support the immune system and body function whether you're in treatment or done with it. I went to him due to problems I was having with my take down surgery (i.e. poop problems!) and he helped me with that. I ultimately ended up opting for a permanent colostomy, but I learned SO MUCH from this doctor. There are other Naturopath's in our area with lower prices - this is just one example. I'm sure prices vary by region of the country as well. Keep in mind that supplements the Naturopath prescribes will represent a significant cost as well - as much or more than their office fees in many cases. Of course this all varies by individual patient and doctor - so this is just a rough idea of costs.
My acupuncture therapist charges me $50 a visit as I don't have insurance. I saw an excellent chiro/Nutritionist the other day and I was charged $56 and she spent over an hour with me and my daughter. These are what I would consider to be on the lower side of costs.
I think the challenge with any alternative service provider, and this holds true for traditional doctors as well, is finding one that suits your needs, your personality and your budget. Once you find one provider - for example, for me it was my acupuncture therapist, who you know and trust, they can often refer you to other providers to fill in any other areas of treatment you want to consider.
