Are genetic counseling sessions confidential if the counselor doesn't have an md?

Yes: Genetic counselors and physicians are bound by the same ethical and legal rules of confidentiality.

Depends: Other licensed health care providers also are bound by federal and state confidentiality statutes, but it may be wise to read hipaa froms (fine print) carefully as to who you may be consenting to release in terms or partners, research, hospital systems etc. If the facility or provider does not have a health-related license - confidentiality can be questionable.
