Contact the Mental Health Services Oversight and Accountability Commission.
They read letters, too.
This link will take you to brief biographies of each member of the Mental Health Services Oversight and Accountability Commission. You may have something in common with one or more of these members – from the same area of the state, have a family member who works in the same occupation, etc. The more you personalize your letter, the better chance you have of making an impression.
Send mail to each of them at MHSOAC, 700 N. 10th Street, Suite 202, Sacramento, CA 95814.
