Oscar takes a relational and developmental approach using evidence-based practices (e.g., CBT, CPP, etc.) in working with adults, adolescents, children, and infants.
He specializes in working with individuals and families who have experienced stress, trauma, depression, and anxiety by creating a collaborative alliance that is compassionate and safe, and providing the skills and reflective space to become your best self. Oscar also works with parents/caregivers in helping them strengthen their relationship with their children and addressing behavioral/emotional issues that may be present.
