About William
William Castillo is a licensed mental health counselor with 18 years of experience. He helps people manage stress, anxiety, depression, trauma, and relationship concerns in a direct and practical way. Sessions focus on clear goals and steps that fit each person's daily life.
He draws on evidence-based therapeutic techniques to address issues such as low self-esteem, abandonment and attachment concerns, and difficulties with communication. William also works with people facing substance problems, domestic violence aftermath, and the emotional effects of chronic illness such as cancer.
How William works
He pays attention to how immigration, blended family situations, and fatherhood stress can affect wellbeing. William emphasizes a respectful, culturally aware approach. He listens for each person's background and tailors strategies accordingly.
The work can include learning new ways to cope with intense feelings, reducing impulsive responses, and rebuilding trust after infidelity or separation. Practical skill-building is a common part of sessions. That may mean rehearsing difficult conversations, setting boundaries, or developing routines to steady mood.
He helps people spot patterns that keep problems going and then try small experiments to change those patterns. People can expect collaborative care that focuses on next steps. William aims to make therapy understandable and useful for everyday life.
He offers sessions in English and accepts international clients while practicing under his Washington LMHC credential.

Online support options
Evidence-based approaches and flexible online care
William uses evidence-based therapeutic techniques to help people make practical changes. One common approach focuses on recognizing and changing unhelpful thought and behavior patterns to reduce anxiety and depression; it helps people test new ways of thinking and behaving. Another approach centers on processing traumatic experiences in smaller steps so memories feel less overwhelming and everyday functioning improves. Finding the right approach is part of the work. William collaborates with each person to choose methods that match their needs, goals, and preferences. Together they review what’s helping, what isn’t, and adjust the plan as therapy continues. Online sessions are offered by video calls, phone sessions, live chat, or text-based messaging to make therapy fit into busy lives. Video lets people maintain face-to-face interaction, phone can be easier when bandwidth is limited, live chat supports shorter check-ins, and messaging is useful for ongoing reflection between sessions. These options support continuity of care and let people access therapy from different locations and schedules.Start online instead of waiting
