How his approaches fit into online therapy
William draws on mindfulness therapy to help people learn to notice thoughts and sensations without getting swept away, which can ease anxiety, depression, and chronic pain. Attachment-based work focuses on how past relationships shape current patterns, helping people understand trust, closeness, and emotional needs. Client-centered therapy keeps the conversation grounded in each person’s goals and values, with the therapist following the client’s lead and offering gentle reflection.
Choosing the right mix of approaches is a collaborative process. He will work with each person to weigh goals, preferences, and what has helped in the past, then adjust methods as the work unfolds. The aim is to find practical tools that fit the client’s life rather than forcing a single technique.
Session formats are not listed in the biography, so confirm current options before booking. Online therapy can make it easier to fit sessions into a busy week, shorten routine check-ins, or allow a quieter setting that reduces travel time. Many people find remote sessions helpful for keeping momentum between in-person visits or for using mindfulness exercises from everyday environments.
