We place a high value on the confidentiality of the information that our clients share with us.  We make every reasonable effort to safeguard the personal information of the client. If for some reason there is a need to share information, clients will be consulted and asked to sign a form authorizing a transfer of the information.  There are several instances when confidential information may be released to others, a few are:

  1. a referral of a client by the Court
  2. Clients involved in litigation and informed the court of the services that they received from us
  3. Clients threaten to harm themselves or others
  4. Abuse or neglect of children
  5. when clients waive their rights to have their records protected
