Daniel J. Ahearn, LMFT

My clinical work centers on attachment repair: helping people change not just how they think about their relationships, but how their nervous systems experience safety and connection.

I’m a licensed marriage and family therapist and certified alcohol and drug counselor. I trained directly with Dr. Daniel P. Brown and Dr. David Elliott in Integrative Attachment Therapy beginning in 2018. I serve as Director of Culture at Ascend Healthcare, a residential treatment program for adolescents in Los Angeles, where I run attachment repair groups and lead clinical training. My private practice focuses on men’s attachment work, father-teen repair, and families navigating the hardest years.

How I think about this work

Most people I work with aren’t broken. They’re adapted. What looks like emotional unavailability, withdrawal, chronic conflict, or anxious pursuit is almost always an attachment strategy that once made sense. A child who learned that needing things brought punishment learns not to need things. A child who learned that love was inconsistent learns to stay hypervigilant. Those strategies become personality. They become relationship patterns. They become the thing that wears people out.

The work isn’t to override those patterns through willpower or insight. It’s to give the nervous system something it never had: a felt experience of safety, attunement, and genuine care, repeated over time until a new foundation forms. That’s what the Ideal Parent Figure protocol does, and what Integrative Attachment Therapy is built around.

I’m particularly drawn to father-teen repair because it’s underrepresented clinically and deeply consequential. Paternal attachment shapes adolescent identity, risk tolerance, emotional regulation, and the templates teens carry into their own adult relationships. A father who does this work doesn’t just change himself. He changes a family system.
