Mariana Psyrdellis, HCPC

Mariana Psyrdellis is a psychologist registered with the HCPC in the United Kingdom with 12 years of professional experience. She focuses on thoughts and everyday habits to help people manage stress, anxiety, low self-esteem and depression. Mariana aims to make the first steps toward change feel safer and more manageable for each person she meets.

She speaks English and Spanish and has worked in clinical and academic roles, including research and teaching. That background informs a practical approach that blends psychological knowledge with everyday problem solving. Sessions are shaped to fit the person’s specific issues, goals and circumstances.

Mariana pays attention to how family, social context, identity and biology interact to shape behaviour and mood. She adapts conversations and plans so they reflect those individual details. This means looking at patterns of thinking, daily routines and relationships to find small, realistic changes.

People come to her for help with relationship strain, communication problems, abandonment and attachment concerns, body image, caregiver stress, and the fallout of separation or infidelity. She also supports those dealing with addiction, guilt and shame, immigration stress, isolation and impulsivity.

Her stated style is compassionate, respectful and flexible. She works with each person to tailor the dialogue and a plan that fits their life, rather than applying one set method to everyone. That personalised focus is intended to support steady, achievable progress.

How therapeutic approaches shape online therapy

Mariana draws on evidence-based therapeutic techniques that focus on thought patterns and daily habits. One common strand involves identifying unhelpful thoughts and testing them against real-life evidence, which helps reduce worry and low mood by changing how people interpret situations. Another part of her approach looks at routines and small behaviour changes - adjusting daily activities can improve mood and increase a sense of control.

Choosing the right approach is a collaborative process. The therapist will discuss goals, preferences and practical needs and then agree a plan together. That plan can change over time as progress is reviewed and new priorities emerge.

If you are considering online therapy, confirm the session formats available before booking, as the biography does not specify formats. Online work can make it easier to fit sessions into a busy week, reduce travel time, and allow people to meet without rearranging their whole day. It can also allow shorter check-ins when a brief review is helpful, or audio-only conversations when video is difficult. Discussing which ways of meeting suit you best is part of the first steps with the therapist.
