About Sonya Sanmateu, LCSW

I believe you don’t need to be fixed—you need to be understood.

I’m an online therapist based in Bucks County, PA and serving clients across PA & NJ. I specialize in eating disorders, disordered eating, anxiety, & big life changes.



The things that brought you here today? There’s a reason for them.

Whether it’s an eating disorder, harsh self-talk, or those people-pleasing patterns you can’t seem to break—these are not “flaws.” They’re invitations to tune in to what those symptoms are really trying to tell you.


Because meaningful change begins with compassionate understanding.


Often, no one has higher standards for themselves than my clients. They are the women who do “all the things” and still feel like it’s not enough. They often appear composed and in control, even when inside they feel consumed by stress, pressure, or self-expectations. And while they are insightful and caring with others, they often struggle to offer themselves the same compassion.

In our work together, I’ll help you honor the strength & success that’s gotten you here, while freeing you from the things that no longer serve you: the self-talk you’d never use with someone you love, the pressure that isn’t actually yours to carry. By uncovering the deeper roots of what brought you here, you can grow in compassion toward your own mind, body, and experiences and come home to a version of yourself that finally feels safe, grounded, and, above all, enough.

My approach:

Exploring the “why” beneath the “what,” then building new ways to respond.

I view therapy as both an exploration and a collaboration. Together, we’ll examine the patterns, experiences, and emotions that have shaped how you cope today—and then identify what’s no longer serving you. In addition to making sense of what’s underneath, we’ll also explore new, more supportive ways of relating to yourself and navigating your life. That can look like developing more supportive and sustainable ways to manage stress, process emotions, and care for your needs.

At the end of the day, this is a process that will honor your story and go at your pace, all with a deep belief in your capacity for genuine, lasting change.


Therapy with me is…

  • With years of experience in higher levels of care—including residential, PHP, and IOP—I bring deep expertise in my specialties, so you know you’re sitting down with someone who truly ‘gets’ it.

  • Creating space where you can show up as you are—without fear of criticism. Recovery is never linear, and I’ll offer patience, flexibility, and steady support at every stage.

  • Helping you uncover what’s underneath your habits or patterns, make sense of them, and then translate that insight into lasting change.
