It is very important to have a GOOD chiropractor. If she did not see an improvement in the past month, why did she continue having you come in so much. Usually a good chiropractor will recognize sooner that they have done all they can do. Perhaps a different one, that you know is better, can examine to make sure nothing is out of place. Especially after an accident you have to be very carefull. A Naturopathic doctor would be good.
