Matthew Masolini, LMFT, helps patients across California stabilize, heal, and reclaim control of their lives during some of their most challenging moments. He provides individual therapy for adults, offering a steady, nonjudgmental presence for those navigating anxiety, depression, relationship strain, and major life transitions.

Matthew is especially passionate about working with individuals who have been recently discharged from a psychiatric hospital or who are participating in court-ordered treatment. He understands the uncertainty, fear, and pressure that often come with these circumstances and offers structured, compassionate, and goal-focused support to help patients rebuild stability, confidence, and healthy daily functioning.

His clinical expertise includes treating PTSD/trauma, anxiety, and couple’s issues, and he offers additional support for conditions such as bipolar disorder, OCD, ADHD, and sleep disturbances. Matthew also helps patients facing grief, substance-related challenges, or gender-identity exploration, providing a grounded and affirming therapeutic environment.

Matthew draws from Cognitive Behavioral Therapy, Acceptance and Commitment Therapy, and EMDR, integrating additional modalities such as DBT, mindfulness, and exposure-based work depending on the needs of each patient. He works with diverse communities, including LGBTQ+ individuals and military veterans, and welcomes men and women seeking a collaborative and practical path toward emotional wellness.

Outside of his professional role, Matthew values creativity and balance. In his personal time, he can often be found reading unexpected book recommendations, writing, or playing the guitar- activities that help him remain present and energized for his clients.
