About Justyna Garzennec

I am a highly experienced, accredited Cognitive Behavioural Therapist and Interpersonal Psychotherapist, with 18 years' experience working in a busy NHS psychological therapy service and 7 years in private practice. I offer therapy online and in calm, welcoming consulting rooms in Central London.

My work is grounded in warmth, empathy and collaboration. I aim to offer a safe, respectful and non-judgemental space where you can explore your challenges, understand the patterns that may be holding you back, and begin developing practical strategies that support lasting change.

I carry out comprehensive clinical assessments and provide psychological interventions for people experiencing depression and a range of anxiety-related difficulties, including panic disorder, health anxiety, obsessive-compulsive disorder, social anxiety, specific phobias, generalised anxiety disorder and post-traumatic stress disorder.

I also specialise in helping people who struggle with high self-criticism, perfectionism, low self-esteem and stress — including work-related stress or burnout — as well as people whose depression or mood-related difficulties arise in the context of relationship challenges.

Alongside my clinical work, I also provide supervision to qualified CBT therapists and therapists in training.

Our Work Together

How We Will Work Together

Starting therapy can feel daunting, especially if it's the first time you're sharing your inner world with someone else. My priority is to help you feel safe, understood and valued, so that trust can develop at a pace that feels right for you. I bring a naturally warm, empathetic and compassionate style, and I hold a deep respect for each person's individuality and humanity.

I draw flexibly on a range of therapeutic approaches, depending on what you need at any given time. In our first session, we will explore your difficulties, clarify your goals, and agree on how we will work together. If you've had previous therapy, we can reflect on that too, so this experience feels grounded and supportive from the start.

Depending on your goals, we may work on gently challenging unhelpful or self-limiting thoughts, developing greater acceptance of difficult feelings, building specific skills such as assertiveness, or cultivating a kinder, more compassionate relationship with yourself — especially if high self-criticism plays a role in your difficulties. Where helpful, we may explore past experiences in more depth to understand how they have shaped the beliefs you hold about yourself and others, and work on shifting the beliefs that no longer serve you so you can begin to experience yourself and your life in a healthier, more balanced way.

Sometimes emotional distress is linked to significant interpersonal events — such as bereavement, relationship changes, conflict, or feelings of loneliness and isolation. At other times, it may follow major life changes, including job loss, changes in physical health or other important transitions. When low mood or emotional overwhelm takes hold, it can become harder to navigate relationships, which in turn can intensify how we feel. In therapy, we will focus on helping you understand and work through these experiences, develop healthier ways of relating to others, and build more satisfying and supportive connections - all of which can have a powerful positive impact on your wellbeing and quality of life.

Throughout therapy, we will regularly review your progress to ensure that our work remains aligned with your needs and goals.

When life feels difficult, therapy can help you find a way forward.

Many people come to therapy because the ways they have been coping no longer feel enough. You may feel overwhelmed, stuck, anxious, low, disconnected, or unsure how to move forward.

Therapy offers time and space to understand what is happening, explore what may be contributing to your difficulties, and build new ways of responding to life's challenges.

A central part of my work is helping people recognise and draw on their own inner strengths and personal resources. I believe this is an important part of building resilience, confidence and a greater sense of emotional wellbeing.
