About Sonya Sanmateu, LCSW, CEDS
I believe you don’t need to be fixed—you need to be understood.
I’m a licensed clinical social worker and Certified Eating Disorder Specialist (CEDS) based in Bucks County, Pennsylvania, offering online therapy across Pennsylvania, New Jersey, and New York.
I specialize in the treatment of eating disorders, disordered eating, and body image concerns, and also support individuals navigating anxiety and life transitions.
My clinical background includes extensive experience across residential treatment, partial hospitalization (PHP), intensive outpatient (IOP), and outpatient settings, supporting individuals navigating complex relationships with food and their bodies.
My work is grounded in evidence-based eating disorder treatment and informed by mindfulness, embodiment, and compassionate curiosity. I help clients better understand the patterns shaping their experience, reconnect with themselves and their bodies, and move toward meaningful, lasting change.

The things that brought you here today? There’s a reason for them.
Whether it’s an eating disorder, harsh self-talk, or patterns you can’t seem to shift—these experiences don’t come out of nowhere. They often develop for a reason, even if that reason isn’t immediately clear.
Together, we’ll begin to understand what these patterns may be protecting, managing, or trying to communicate—and what might become possible beyond them.
Because meaningful change begins with compassionate understanding.
You may be someone who appears composed and capable, while internally carrying pressure, self-criticism, or exhaustion. You may be used to showing up for others, meeting expectations, and holding it all together—even when it comes at the expense of your own needs, emotions, or sense of self.
In our work together, we’ll honor the strength that’s gotten you here, while also creating space to question the patterns that are no longer serving you. By understanding the deeper roots of these patterns, you can begin to relate to yourself with more compassion and move toward a version of yourself that feels more grounded, authentic, and at ease.
My approach:
Exploring the “why” beneath the “what,” then building new ways to respond.
Together, we explore the patterns, experiences, emotions, and internal narratives that may be shaping how you relate to yourself today. From there, we focus on developing more supportive ways of relating to yourself, your body, and your life.
At times, we may slow things down and notice what’s happening in the moment—your thoughts, emotions, or physical sensations. This can help deepen awareness and support meaningful change, especially in patterns around food, movement, and self-criticism.
This process honors your story, moves at your pace, and is grounded in the belief that meaningful, lasting change is possible.
