IFS Therapy in New York City and Westchester


Internal Family Systems is not a technique. It is a different way of understanding why you feel what you feel, and what to do about it.

Amanda Phillips LCSW IFS therapy New York City and Westchester

Most therapy approaches ask you to change what you think, do, or feel. Internal Family Systems asks a different question: what are those thoughts, behaviors, and feelings actually protecting? That shift in orientation is why IFS tends to reach something that other approaches often don't. And it is why the people who find this work most useful are often those who have already tried other things and found them helpful but not quite enough.


What IFS actually is

Internal Family Systems was developed by Dr. Richard Schwartz in the 1980s and has since become one of the most well-researched models in practice. The core idea is simple, though its implications run deep. IFS understands the mind not as a single unified self but as a system of parts. Each part has its own feelings, beliefs, protective strategies, and history.

These parts are not problems to be eliminated. They are protective adaptations that developed in response to real experiences and have been working hard ever since to keep you safe, functional, or both. The problem is not that they exist. The problem is that they are often running on outdated information, at significant cost to the rest of the system.

What happens in an IFS session

Clients don't usually describe the change as dramatic. It's more like: things that used to take all your energy start taking less. Patterns you couldn't interrupt start becoming visible before they run. The body starts to register something closer to ease, even briefly, and then a little more often.

More specifically, over time clients find:

The patterns make sense rather than feeling like character flaws. There's a reason the anxiety developed and understanding that reason changes the relationship to it.

There's more space between what happens and how they respond. Less reactivity, more choice.

They trust themselves more. Their instincts, their limits, their sense of what they actually need.

They feel steadier. Not because life has gotten easier or the health condition has resolved, but because their relationship with their own internal experience has genuinely changed.

That steadiness is what this work is actually for.

What IFS is particularly well-suited for


  • Anxiety that never powers down

    IFS reaches the protective parts driving vigilance and creates conditions for genuine safety rather than managed anxiety.

  • Anxiety alongside chronic illness

    Addresses the body-based dimension of chronic vigilance directly, working with parts that have been monitoring and bracing on behalf of a body that learned it could not fully trust physical safety.

  • Trauma

    Non-retraumatizing by design. Moves at the pace of the system, working with protective parts first.

  • Depression rooted in exhaustion

    Works with the parts that have been carrying too much for too long, rather than pushing for behavioral activation before the system has internal resources.

  • Jewish identity and anxiety

    Intergenerational patterns, family systems organized around resilience, the weight of collective history. IFS reaches what standard anxiety treatment rarely does.

  • High-functioning adults

    For people whose anxiety looks like capability, who have tried other things and found them helpful but not quite enough.


The research behind IFS

IFS has a growing and credible evidence base. Key findings include:

  • Journal of Rheumatology: IFS produced significant improvements in pain and physical function in rheumatoid arthritis patients, with benefits sustained one year later.

  • Clinical Psychologist (2025): IFS identified as a promising therapeutic approach for anxiety, trauma, depression, and chronic pain.

  • SAMHSA has rated IFS as a promising intervention for generalized anxiety.

My IFS training and approach

I am IFS Level 1 trained through the IFS Institute and listed in the IFS Institute practitioner directory. My work integrates IFS with trauma-informed therapy, understanding that the two frameworks complement each other naturally. IFS provides the map for understanding the internal system. Trauma-informed care ensures that the pace and approach of the work honors the nervous system's capacity at any given moment rather than pushing past it.

I use IFS as my primary clinical framework rather than as one tool among many. That means every session is oriented around the question of what parts are present, what they are protecting, and what they need, rather than moving between different techniques depending on what comes up.
