All About Mattie
Mattie SimBarcelos is a Marriage and Family Therapy Intern at Thomas Jefferson University who believes therapy works best when it is collaborative, authentic, and rooted in real human connection. She approaches therapy as a shared process, one where clients are met with curiosity, respect, and care as they make sense of their inner world and relational patterns.
Her work is grounded in an embodied understanding of healing. By integrating somatic practices, Mattie supports clients in developing greater awareness, emotional regulation, and a felt sense of safety within their bodies and relationships. Therapy is not just about insight, but about learning how to stay present with yourself in moments that once felt overwhelming.
Mattie brings a multidisciplinary lens to her clinical work. She holds a master’s degree in liberal arts with a certificate in global studies and draws from her experiences as a certified yoga instructor, full-spectrum doula, and artist. These roles shape a holistic approach to therapy that honors each client’s lived experience, creativity, and resilience.
As a queer therapist, Mattie is especially committed to creating affirming and brave spaces for BIPOC clients, individuals navigating prenatal and postpartum experiences, and those moving through identity shifts, relational changes, and major life transitions. Her style is compassionate, grounded, and genuine, working alongside clients to deepen self-trust, foster resilience, and support sustainable healing.

✔️ Clients seeking greater mind-body connection and emotional regulation
✔️ BIPOC individuals looking for culturally responsive and affirming care
✔️ Queer clients exploring identity, belonging, and self-trust
