What to expect

Prior to our first session we offer a free 15 minute telephone consultation to help you decide whether therapy can be helpful for you. During initial sessions you will be asked questions about your current difficulties and your hopes for therapy. Following this an individualised treatment plan will be agreed between you and your therapist, including an estimate of the number of sessions required, to help you to address some of the areas you wish to work on.
The length of treatment varies from person to person, however, most difficulties can be effectively addressed within 6-20 sessions, with each session lasting for 50 minutes.

Harriet truly is a one of a kind therapist that utilises her empathy and knowledge in conjunction with her kind and proactive nature to really engage with any individual allowing them to feel entirely at ease, creating a much more effective and productive environment to remedy whatever may be troubling them at that time. Would highly recommend Harriet to anyone that is currently looking for a therapist as she really has made a positive impact on my life - thank you Harriet!

I made good progress through my sessions with Harriet. She is an empathic person who is easy to talk to, has a great deal of knowledge, and was able to offer me a constructive plan. I would definitely recommend Harriet to anyone considering therapy.

Client - 2020


I have had a truly wonderful experience which has changed my life and how I manage my anxiety for the better. I have got more out of CBT than I could ever have hoped and have Harriet to thank for that - she is amazing at what she does, she makes you feel at ease from your first session and has equipped me with practical tools and strategies that I can use going forward to help me manage my anxiety and make a positive impact on my life. Thank you!

Therapy has been a massive help to helping come to terms with the recent diagnosis and having to live with a life long condition. Having had therapy I would be open to future sessions in the future if needed as I have found the results to be very positive for me.

Client - 2021


Harriet has been a fantastic source of strength, insight and compassion which I have no doubt has considerably shortened my road to recovery.
