About me
My aim to provide the best possible mental health care to those I work with by practicing within well-established, evidence-based psychological models that adhere to The NICE guidelines.
I am recognised by all major insurance companies and also welcome self-funding individuals.
I am an experienced clinical psychologist with over 20 years of dedicated practice in the field of adult and older adolescent mental health. My approach is both compassionate and evidence-based, specialising in providing therapy to individuals navigating a wide range of psychological challenges. My work spans anxiety, depression, trauma, relationship issues, and personality disorders. Or you may be struggling with something vaguer, such as feeling lost or not reaching your full potential. Whatever you are struggling with, together we can get you to a better place.
I completed my clinical training on the Oxford Doctoral Course of Clinical Psychology which is closely affiliated with the Oxford Cognitive Therapy Centre, a centre of excellence for Cognitive Behavioural Therapy (CBT). I have post-doctoral qualifications in Cognitive Analytical Therapy (CAT), Dialectical Behavioural Therapy (DBT) and Eye Movement Desensitisation Reprogramming (EMDR). Rather than working purely within one model, I tend to draw flexibly on all of these models in order to tailor my approach to match the needs of those I am working with.
Throughout my career, I have worked in diverse settings, including the NHS and private practice. I am committed to ongoing professional development and am registered with the British psychological Society (BPS), The Association of Cognitive Analytical Therapy (ACAT), The Health and Care Professions Council (HCPC) and adheres to the code of ethics set for these governing bodies.
What my clients say
Dr Blackwell is an outstanding psychologist. She has a wealth of skills and is highly personable. I trust her completely and have seen some remarkable yields from her involvement in people’s lives, from times of vulnerability to those of strength.
Siobhan listens, understands and collaboratively empowers people to believe in themselves, connect with the world and feel resilient. She retains professionalism, humility, a good sense of humour and will stand shoulder-to-shoulder with you on an unwavering journey of hope. I highly recommend her caring, thoughtful and methodical approach to shared success.
Everything Siobhan says is said with the purpose of getting you to where you want to be. She is direct, honest and without her I could never have broken the lifelong patterns of self-sabotage I was struggling with. My life now is where I want to be.
