She helps clients build emotional awareness, set healthy boundaries, and cultivate self-compassion, addressing both the “why” behind patterns and practical tools for change.

Monique begins by exploring each client’s story, history, and goals. Together, they create individualized, evidence-based treatment plans, regularly adjusting as needed. Sessions are collaborative, providing insight, practical tools, and emotional support to apply in real life. Progress is measured not only by symptom reduction but by increased self-awareness, emotional stability, and confidence in navigating challenges.
