About William
William Castillo is a Washington LMHC with 18 years of clinical experience helping adults manage stress, anxiety, depression, trauma, and relationship concerns.

Sessions focus on clear goals, practical coping skills, and understanding how past experiences shape current reactions. Conversations are direct and concrete, with an emphasis on small steps that make daily life easier.
Many clients come for help after major changes - a new marriage, a blended household, or immigration. He also supports people facing substance use, domestic violence histories, cancer-related stress, and fatherhood challenges. He understands how loyalty conflicts and shifting roles can affect mood and relationships.
William adapts standard clinical methods to each person's situation. He aims to improve communication, reduce overwhelming emotions, and rebuild confidence. Therapy can include focused skill practice, tracking patterns between sessions, and reviewing progress in measurable ways.

Evidence-based approaches and online sessions
William uses evidence-based therapeutic techniques that focus on changing unhelpful patterns and building coping skills. One common method is structured, skills-based work that teaches concrete strategies for managing anxiety and depression, such as breathing, grounding, and behavior changes to reduce avoidance. These tools are useful for day-to-day symptom relief and for handling stress in blended household situations.A second approach emphasizes understanding attachment and relationship patterns. This involves looking at how early relationships influence current reactions, practicing clearer communication, and trying new ways of relating. That approach is helpful for people dealing with loyalty conflicts, co-parenting tensions, or repeated relationship rifts.
Finding the right approach is part of the work. The therapist will collaborate with each person to choose methods that fit their goals, preferences, and the problems they bring. Treatment plans can shift as needs change and progress is reviewed together.
