Should I trust a health care provider that offers other therapies that I consider fraud?

We have two beautiful children, a set of 7 years old identical twins. Sharing the same genetic code, they share many of their talents and challenges. One of their (few) challenges lies in their fine motor skills, which makes it harder for them to learn to write.

Their school suggested a physical therapist (or physiotherapist) specialized in children, which they have good experiences with. Our initial contacts so far have proven pleasant and promising. Checking out their website, however, I noticed they offer some other therapies as well, tat I consider highly disputable. For instance: therapy aimed at infants in which they stimulate the neck muscles and vertebra to combat the KISS-syndrome. (Most of the scientific world considers this syndrome as nonsense and this therapy as dangerous.)

My dilemma is that my wife and I are about to hand our children into the care of people that work for the same ‘clinic’ that offers therapies we both consider to be fraud. My wife’s thinks we should just continue since we will not be ‘using’ the disputed therapies and most if not all physiotherapists are engaged with the ‘alternative scene’ in some way or another.

I am hesitant, since I feel we are about to engage with people that work in a highly questionable facility.

I would appreciate your thoughts
