Holly Daniels, PhD, LMFT

Holly Daniels, PhD, LMFT, is a licensed marriage and family therapist, meditation teacher, and mental health advocate.  As director of Advance LA, she oversees the management of the program and works closely with administration, staff, and coaches on behalf of its clients and residents.

Holly has had several roles in mental health treatment centers, including Primary Therapist, Clinical Director, Academic Director, and Outreach Director. She has worked with teams at Monte Nido and Associates, the Valley Community Clinic, The Canyon in Malibu, and Sober College residential treatment center, where she specialized in helping  young adults with complex issues including co-occurring addictions, eating disorders, post-traumatic stress disorders (PTSD) and associated mood and anxiety disorders.

Holly believes that strength-based, solution-focused techniques work best with young adults who need support moving forward into healthy independence.  She enjoys the team approach at Advance LA, which encourages clients to know their own strengths while teaching the skills necessary for building connections with family, friends, coworkers and others – creating and sustaining fulfilling and productive lives and livelihoods.

As a mother of two teenagers, one of whom was identified with ASD as a toddler, Holly understands firsthand the many difficulties young adults face as they navigate through life and try to find balance between independence and healthy interconnection.  She finds joy in helping clients and family members progress and celebrate the milestones along the way.
