Suggest Treatment For Oppositional Defiant Disorder

Hi I believe my 11 yr old daughter has ODD in addition to ADD, although she does not act out in school or public places she does unload at home.I am her target, I have talked with her ADD Dr. and she does take Concerta, I do work with keeping consistency in home, but the real problem is her father he seems to undermine and re-enforce her bad behavior. What else can I do? Very tired Mom
