About William
William Castillo is a Washington LMHC with 18 years of clinical experience. He works with people who are dealing with stress, anxiety, depression, trauma and relationship problems, and he lists social anxiety among the concerns he addresses.
William keeps sessions straightforward and practical. He listens to what is happening now, then helps people name the patterns that are getting in the way. Conversations focus on small, doable steps clients can try between visits to test what helps in everyday life.
His work uses evidence-based therapeutic techniques to address mood concerns, trauma responses, and relationship difficulties. He pays attention to family history, attachment issues, and common complications such as substance use or co-morbid conditions. That practical attention helps when problems stack up across work, home, and intimate relationships.
William also offers help around communication problems, divorce and separation, infidelity, and the stress of immigration or blended family dynamics. He includes support for people facing medical challenges such as cancer and the emotional strain that can follow.
People who want to start are asked to complete a short matching questionnaire and schedule an initial session. William works to make the first appointment clear and manageable for someone who finds reaching out difficult.
Approaches to online care and how they help
William uses evidence-based therapeutic techniques to guide online sessions. One approach focuses on building skills to manage anxiety symptoms by breaking situations down into smaller steps and practicing new behaviors in real life. This helps people who find social settings or speaking up difficult by making exposure gradual and concrete.Another approach targets patterns from past relationships and attachment history. Sessions look at how early relationship experiences influence current reactions and communication, and then try new ways of relating that reduce repeated conflict or avoidance.
Finding the right method is part of the work. William collaborates with each person to choose which techniques to try first, adjusting the plan as progress and preferences become clear. He checks in about what feels useful and what needs changing so the approach fits the client's goals.
