Are there any Sugar Glider Vets in Rhode Island?

I am looking for a vet that deals with sugar gliders but I cant seem to find any nearby. I have one male that is byhimself he is very aggressive I have tried working with him for almost a year and he is just way to stubborn. In a seperate cage I have a female with I believe 2 joeys in pouch her (husband)and thier 5 mth oop son and I would like to have the males fixed I dont wanna seperate the 3 if I dont have to because they are all very friendly get along well and are hand tame but I also dont want the mother to become a (baby factory) its not fair to her plus that will be to many for me to handle. Does anyone know where the closest vet is to or in Rhode Island? Also does anyone have an idea on pricing? Thank you very much in advance
