His practice is based in Washington and he communicates in English. He accepts international clients through the practice process and uses a subscription model for sessions that can be canceled at any time.

How evidence-based methods translate to online work

William uses evidence-based therapeutic techniques that focus on practical change. One common approach is skill-based work that helps people learn tools for anxiety and mood management, such as breathing strategies, behavioral experiments, and activity planning to reduce avoidance. This helps when worry or low mood gets in the way of daily life.

Another useful method is trauma-informed processing, which aims to help people name and understand how past hurt shows up now. That can mean pacing difficult memories, rebuilding safety in relationships, and practicing new ways to respond when stress feels familiar.

Choosing the best approach is a team effort. William explores a person’s goals, what has helped before, and current life demands. He then suggests methods to try and adjusts them based on what works in real life. The plan is collaborative and reviewed as progress happens.

For online work, confirm the specific session options before booking so you know what formats are offered. Online sessions can make it easier to fit therapy into a busy week, reduce travel time, and allow shorter check-ins when a full session isn’t needed. Licensed professionals can adapt exercises and homework to remote appointments so progress continues between meetings.
