About William

William Zahn is a licensed psychologist who focuses on helping people manage stress, anxiety, depression, grief, relationship challenges, and other life disruptions using a thoughtful, person-centered style.

Background and approach

With 20 years of clinical experience, he draws on a range of evidence-informed methods to tailor care to each individual’s needs, emphasizing compassion, respect, and practical strategies that fit a person’s natural way of being.

He trained at Princeton University and earned a PsyD from CSPP-San Diego, and his practice includes work with ADHD, addictions, LGBT concerns, trauma and abuse, sleep problems, and coping with chronic pain, illness, or disability.

William also brings skills in mindfulness and mind-body practices, and he aims to help clients align therapeutic work with their personal goals rather than asking them to conform to an external ideal. In sessions he integrates approaches such as Internal Family Systems alongside attachment-informed and cognitive-behavioral techniques, offering a collaborative, respectful environment that supports self-understanding and practical change.

He works from California and conducts therapy in English.

Integrative Approaches and Online Access



Internal Family Systems (IFS) views the mind as composed of different parts that hold various emotions, beliefs, and impulses; IFS work helps clients identify those parts, build compassionate inner leadership, and reduce internal conflict, which can be useful for anxiety, trauma responses, and issues like shame. Attachment-Based Therapy focuses on how early and current relational patterns shape feelings of safety and connection, helping people reorganize relational expectations and improve emotional regulation in close relationships. Client-Centered Therapy emphasizes a nonjudgmental, empathic therapeutic stance that supports self-exploration and personal growth by prioritizing the client’s experience and goals.

Finding the right approach is part of therapy, and he collaborates with each person to determine which methods fit their needs, goals, and preferences. That may mean emphasizing relational work, guiding inner parts exploration, or teaching practical cognitive and behavioral strategies depending on what arises in sessions.

Online therapy options include video calls, phone sessions, live chat, and text-based messaging, offering flexibility for different schedules and communication styles. These formats make it easier to maintain continuity of care while adapting methods like mindfulness, skills training, and parts work to the medium, and they allow clients to choose the interaction mode that feels most helpful for them.
