Therapy Sessions

We begin with an introductory assessment. In this session we discuss your history, concerns, aims and expectations in order to assess which methods and strategies will suit you best.

The next step is to develop an initial collaborative plan addressing the issues identified during our assessment, then monitor its progress in individual sessions of about 50 minutes in length.

Finally, at the end of the process we will review your progress, identifying what the biggest challenges were, which techniques worked best, and give further recommendations if needed.

Sessions can be held in English or Hebrew.

About the service

I provide online and in-house psychology and psychological executive mentoring services.

I believe that modern life and the job market, with ever increasing demands to excel and get ahead, may be exciting but at the same time can be very wearying. Whether we are successful or not, we are likely to pay a high price for our attempts to reach our full potential. This can damage our well-being, our ability to be productive, creative and innovative, and even our relationship with families, friends or colleagues.

I believe that a high-quality psychological executive mentoring service, utilising the most effective methods that psychology has to offer, should be available to anyone who wishes to cope better with life’s challenges, to improve their performance, and to live a more meaningful life.

I provide online and face-to-face services so that our clients can always get the help they need, when and where it suits them best.

One-to-One Therapy
Therapy Session

One-to-one therapy aims to improve an individual's well-being, remedy or moderate any unhelpful behaviours, improve relationships and help an individual to cope better with life’s challenges. A systematic exploration of the individual’s difficulties based on proven evidence-based models, in a warm, confidential, non-judgemental environment which encourages growth. A usual one-to-one therpay starts with an assessment aimed to identify the main diffculties and the different facotrs that impcat it. At the end of this phase we will have a full formulatin that relfects the main challnges, the factors that influence it, and an intital model to inorm our treatment ahead. In order to get the best results I use an eclectic approach to tailor-fit the best avilable model to my clients needs (I draw my work on Cognitive Behavioural Therapy, different psychodynamic models, Accapatnce and Commintment Therapy, and Compassion Focused Therapy)

Imposter syndrome
Imposter syndrome

Imposter Syndrome is a very common and normal experience for both men and women, usually experienced as persistent self-doubt about one's achievements. The typical thoughts that characterise this condition could be: “I am not as bright as people think I am”, or “I am not as talented or smart as people think I am”. Consequently, people can be convinced that they are frauds and fear that others are about to expose them as imposters in any moment. This fear remains despite evidence to the contrary. It can damage one’s well-being and mental health and can, in extreme cases, prevent individuals from fully engaging with life and work. 

Research has suggested some possible mechanisms that may be responsible for the condition, and several potential treatments. 

In my clinical work I have specialised in Imposter Syndrome and successfully worked with many people experiencing it. With dedicated work positive change is possible.

Psychological executive mentoring helps those who feel that the stress of their professional lives is placing a strain on their ability to pursue their potential, stay productive and innovative, damages their relationships and their ability to stay happy and live a meaningful life.
