need help with columbian rainbow boa

[aurora]

I've got a 1 1/2 year old clumbian rainbow boa for about a month now. The prvius owner said it never has been striking at anynody unless it was shedding. But since we have the snake it has bit almost everybody who tries to handle it. It eats very well and sheds great, it also love it enclosure. We also feed it in a seperate container. What advice do you guys have to deal with this snake. Please help, it is my 17 year old daughter's snake and she is terrified of it.

Thanks
