About me

I am an experienced Adult and Adolescent Psychotherapist and Counsellor practising counselling and psychotherapy in Harley Street London, Brentwood and Hoddesdon in Hertfordshire. I provide counselling and psychotherapy in a safe, confidential and non-judgmental environment. Within my private practice I work with individuals on an open-ended or time limited basis for an agreed time period, with the aim of enabling you to enhance your life and change unhelpful patterns and behaviours. My Harley Street psychotherapy practice is a short walk from Oxford Circus and Marylebone. My psychotherapy practices in Brentwood and Hertfordshire are within easy reach of public transport or by car.

I am an experienced counsellor and have been successful in helping clients who have experienced difficulties with stress, anxiety, depression, panic attacks, self harm, eating disturbances, relationship issues and bereavement to name a few. I also work with patients who suffer with chronic fatigue syndrome, fibromyalgia and related conditions. Making the decision to look for a counsellor can be daunting, but it is the first step.

My counselling and psychotherapy practices in Harley Street, Brentwood and Hertfordshire offer a confidential, quiet and reflective space where we can explore whatever is on your mind.

What is Psychodynamic Psychotherapy?

Psychodynamic psychotherapy aims to assist you in changing unhelpful thoughts and behaviours in your life. As well as discussing your current situation we will also explore some of your earlier experiences as these may affect you later on in life. Psychotherapy is a safe, confidential and non judgemental space where we will work together to explore and address whatever is troubling you.

Further information

Alongside my work with adults I'm also a trained adolescent psychotherapist. Adolecence is a transitional period of development where both physical and psychological changes are negotiated. It is a turbulent phase and brings with it its own stresses and concerns, for parents as well as the adolescents themselves. If you are a parent who is concerned about their son or daughter please feel free to contact me.

If an adolescent is struggling in any area psychotherapy can assist him or her in negotiating difficult and painful problems which may be holding them back from their full potential. Some problems encountered during adolescence are eating disturbances, peer pressure, exam stress, confusion regarding identity, differences in behaviour at school/home, obsessive behaviours and self harm to name a few.

While adolescence presents with its own stresses and strains, it is also a rich time of development where positive and effective changes can be made.
