Daniel S. Lobel

Daniel S. Lobel is a clinical psychologist whose books address difficult family relationships through structured communication and boundary-setting skills. When Your Daughter Has BPD was published by New Harbinger in 2017 for parents and other relatives seeking to understand borderline personality disorder. The guide explains patterns that can destabilize a household, then introduces approaches drawn from dialectical behavior therapy and cognitive behavioral therapy. Its focus includes responding without escalating conflict, protecting the wider family, setting consistent limits, and encouraging appropriate care. Publisher biographies identify Lobel as an assistant clinical professor of psychiatry at Mount Sinai and a practitioner in private settings. He later wrote a related guide about mothers with borderline personality disorder, continuing his emphasis on practical family responses rather than abstract diagnosis alone.
