Dr. Isabelle Mercer

Dr Isabelle Mercer is a Clinical Psychologist at Schoen Clinic Chelsea, offering specialist therapy for children, adolescents and adults across a full spectrum of mental health challenges. She supports individuals experiencing both common and complex emotional difficulties, with particular expertise in anxiety, trauma, low mood, chronic pain, relational difficulties and self-esteem concerns.

At the heart of Dr Mercer’s practice is the creation of a therapeutic environment that feels safe, compassionate and thoughtfully challenging. She works with people who may feel stuck in recurring emotional or behavioural patterns and helps them understand the origins of these difficulties and how they continue to shape their lives. Her approach empowers individuals to build emotional insight, strengthen resilience and move towards meaningful, lasting psychological change.

Dr Mercer’s background spans NHS and private sector services, where she has supported individuals from diverse cultural and personal identities, including LGBTQ+ clients and people living with long-term health conditions. She brings a warm, sensitive and highly attuned style to her work, tailoring therapy to each person’s unique story, goals and needs.

She draws on a wide range of evidence-based therapeutic modalities, including:

• Acceptance and Commitment Therapy (ACT)
• Cognitive Behavioural Therapy (CBT)
• Dialectical Behaviour Therapy (DBT)
• Compassion-Focused Therapy
• Internal Family Systems (IFS)
• Psychodynamic therapy
• Trauma-focused therapy
• Integrative therapy
• Mindfulness-Based Cognitive Therapy (MBCT)
• Narrative therapy
• Solution-Focused Brief Therapy (SFBT)
• Attachment-based approaches
• Parent-Child Interaction Therapy (PCIT)
• Play therapy

Dr Mercer believes therapy should offer space for vulnerability, exploration and connection, while also providing structure, clarity and opportunities for insight and growth. She is committed to helping individuals feel understood, supported and empowered to make meaningful changes in their lives.
