About me

I’m a Clinical Psychologist who helps people make sense of what they’re going through and find a way forward when life feels overwhelming, confusing, or stuck.

I offer a warm, supportive, and non-judgemental space where you can talk openly about whatever is on your mind. Together, we can explore your experiences, understand the patterns that may be affecting your wellbeing, and work towards changes that feel realistic, meaningful, and right for you.

Having trained and worked in both Poland and the UK, I bring an understanding of how culture, language, and personal history can shape the way we experience, express, and cope with emotional difficulties. I value taking the time to understand each person’s unique story and the context of their life.

I work with both Polish- and English-speaking clients, and sessions can take place in whichever language feels most comfortable and natural for you.

Approach

Treatment Approaches
CFT: Compassion-focused therapyRecommended for those who want to be kinder to themselves and reduce negative self-talk, often using mindfulness techniques.
DBT: Dialectical behaviour therapyRecommended for those who want to learn skills to manage intense emotions and improve their relationships, especially if they feel easily overwhelmed.
Integrative therapy Recommended for those who prefer a flexible approach that combines different therapies to meet their unique needs.

My therapeutic approach is relational, collaborative, and compassionate. I believe that a strong therapeutic relationship provides the foundation for meaningful change, creating a space where you can feel understood, reflect openly on your experiences, and develop a deeper understanding of yourself.

My work is informed by psychodynamic thinking and Cognitive Analytic Therapy (CAT). Alongside exploring current difficulties, we may consider how past experiences, relationships, and ways of coping have shaped the patterns that influence how you think, feel, and relate to yourself and others.

At times, these patterns can leave us feeling stuck in cycles of anxiety, low mood, self-criticism, or difficulties in relationships. Together, we can work to identify and understand these patterns, explore the purpose they may have served, and develop more flexible and compassionate ways of responding to life's challenges.

I tailor therapy to the individual, recognising that each person's experiences, strengths, and needs are unique. My aim is to offer a thoughtful and supportive space where we can make sense of difficulties together and work towards meaningful and lasting change.

Experience

10 years in practice

I am currently working as a Clinical Psychologist in NHS settings, supporting clients who experience difficulties with emotional regulation, relationship challenges, unhelpful patterns, and trauma-related symptoms. My work focuses on helping individuals understand the factors contributing to their difficulties, identify patterns that may be maintaining distress, and develop more effective ways of responding to emotional and interpersonal challenges. I draw on psychological formulation to make sense of complex presentations and guide therapeutic direction.

During my Doctorate in Clinical Psychology, I gained experience across a range of NHS placements, working with children, adolescents, adults, older adults, and individuals with learning disabilities. This allowed me to develop a flexible, lifespan-informed approach to psychological care across diverse settings

Prior to training, I worked as an Assistant Psychologist across community and inpatient mental health services, supporting people in moments of significant distress and emotional difficulty. Much of this work involved sitting with people during periods of crisis, uncertainty, and overwhelm, and helping them find a bit more steadiness as things felt difficult to hold.

Alongside this, I volunteered with Victim Support, offering emotional listening and practical support to people affected by crime. This often meant being alongside individuals in the immediate aftermath of upsetting or life-altering experiences, when
