About William

William Castillo is a Washington-based licensed mental health counselor with 18 years of experience. He helps people facing depression, anxiety, stress, and relationship struggles. He focuses on practical steps clients can use in daily life to feel steadier and more in control.

He works in a culturally aware way and pays attention to each person’s background and story. Sessions are collaborative - he listens, reflects, and helps people set realistic goals. Conversations often focus on managing intense emotions, improving communication, and rebuilding self-worth.

Over nearly two decades he has supported people dealing with trauma and abuse, changes after separation or divorce, and problems tied to addiction or illness. He also helps with attachment wounds, abandonment fears, and blended family challenges. His experience includes work around impulsivity, infidelity, and immigration-related stress.

William uses evidence-based therapeutic techniques to guide the work. That means treatments grounded in research but tailored to the person in front of him. He emphasizes building resilience, practicing new skills between sessions, and tracking small changes over time.

People who choose him can expect steady, straightforward care that balances empathy with practical tools. He aims to help clients regain a sense of direction, strengthen relationships, and reduce the daily impact of depression and anxiety.

How evidence-based techniques translate to online therapy

William uses evidence-based therapeutic techniques to guide sessions, focusing on methods that help people change patterns and manage symptoms. One common approach is skill-based work that teaches practical coping strategies for anxiety and depression, such as identifying unhelpful thoughts and testing new behaviors. Another approach emphasizes trauma-informed care, helping people process difficult memories and reduce their everyday impact through grounding and stabilizing practices.

Finding the right approach is part of the work together. He will talk with each person about their goals, preferences, and what feels manageable, then adapt techniques to fit those needs. The process is collaborative and paced to the client’s comfort level, with homework and small experiments between sessions when helpful.
