About William
William Castillo is a licensed mental health counselor practicing in Washington with 18 years of experience. He works with people facing stress, anxiety, depression, trauma and relationship concerns. He aims to make talking about hard things feel manageable and focused on practical change.
William uses straightforward, evidence-based techniques to help people find relief from intense emotions and rebuild trust in themselves and others. Sessions focus on clear goals, learning new ways to handle thoughts and feelings, and improving communication.
Background and approach
He tailors the work to each person’s history and current needs. He pays close attention to how past wounds - such as abandonment or attachment issues - shape present behavior. He also addresses problems tied to addiction, domestic violence, immigration, cancer, and the strains of blended-family life.
Conversations may cover boundaries, impulsivity, infidelity, or co-occurring problems that complicate recovery. William emphasizes a culturally responsive stance and listens for strengths people already have. Together clients identify small, achievable steps that build confidence and reduce distress.
Progress is tracked in ways that make sense for daily life. People meet with him by video, phone, live chat, or text-based messaging. Those options make it possible to keep therapy consistent around work, caregiving, or relocation.
He accepts international clients and offers services in English.
How evidence-based methods translate to online care
William uses evidence-based therapeutic techniques that focus on changing unhelpful patterns and strengthening coping skills. One common approach helps people identify and adjust thought patterns that worsen anxiety or depression, teaching practical steps to reduce distress and improve mood. Another approach concentrates on relationships and attachment - looking at how past losses or abandonment shape current interactions and building clearer communication and boundary strategies to improve those connections.Finding the right approach is a team effort. The therapist will work with each person to choose methods that match their goals, preferences, and daily life. That means trying a few strategies, reviewing what helps, and adjusting the plan so sessions stay relevant and effective for the individual.
Online sessions offer convenience and consistency through video calls, phone conversations, live chat, or text-based messaging. Video calls allow face-to-face work for deeper conversations, phone sessions are a good fit when bandwidth or screen time is limited, and chat or messaging can support quick check-ins or ongoing reflection between meetings. These options make it easier to fit therapy around work, caregiving, or travel while keeping the work focused and goal-oriented.
