Dr. Ribeiro has worked extensively with children, adolescents, adults, and families in both individual and group settings. She is especially drawn to the healing potential of group psychotherapy and the creative dynamics that unfold in shared therapeutic spaces.
Her clinical and research focus centers on creativity as a vital force in human health — a core human capacity that supports healing, self-discovery, and the experience of being alive. She sees the act of seeking therapy as a creative and courageous step toward transformation.
Dr. Ribeiro offers a therapeutic space where clients can reconnect with their inner life as an integration of their internal and external existence, fostering a sense of a life that feels worthwhile. She supports individuals dealing with a wide range of concerns including anxiety, depression, trauma, grief, PTSD, ADHD, relationship difficulties, perfectionism, shame, life transitions, creative blocks, and existential distress.
Her integrative, depth-oriented approach honors each client’s complexity and potential. Whether working individually, with families, or in groups, Dr. Ribeiro helps clients unveil their inner resources and creative capacities so they can move toward healing and fulfilling lives.
CORIN CHELLBERG, ASW - THERAPIST
Corin received his Master of Social Work from NYU, received psychoanalytic training at the Institute for Contemporary Psychotherapy in New York, and has since been engaged in psychoanalytic training through the Lacanian Compass.
As an undergraduate, Corin studied English literature because he was drawn to the beautiful complexity of language as art and moved by the noble, impossible project of literature’s attempts to explore and communicate the ineffable human experience. He became interested in psychotherapy in its resonance with that impossible project; psychotherapy as an exploration wielding language and relationship in search of knowledge and transformative growth.
Corin is working with Dr. Sacha Bollas to bring psychoanalytic depth to practical problems of actually changing: the importance of willingness as both a precondition for change and a challenge in its own right, the value of including psychoeducation and clinical interviewing in psychoanalytic work, and strategies for avoiding the common pitfall of psychotherapy producing insight but no action. Corin is also working closely with Dr. Bollas in his work with groups and psychoanalytic case management.
Corin believes that every individual he works with in his clinic is absolutely singular, and that this singularity is and must be the north star guiding every treatment. He believes that every individual is who and how they are because of the infinite specificity of everything that has happened to them and how they made sense of it, everything that has been said to them and everything that they said to themselves. This extruded constellation of events and reactions, words spoken and words heard, has momentum and inertia. The work of understanding it and changing requires commitment and patience.
In sessions, he will ask you to say whatever comes to your mind, and he will listen carefully. He will try to understand you and your history, where you are in this particular moment in your life, and what you hope this experience will help you to do or become. He will think about how to be of use, oriented by a goal to which he is committed for every patient. That goal is freedom: your freedom to follow your desire.
