What our patients say

Very happy with the care from Dr. Allen

I have been happy with the care provided by Dr Allen, who has found a combination of medications which have significantly improved some of my symptoms.  I do not yet regard myself as "cured", and I think Dr Allen would agree that my treatment is ongoing.  I am pleased that Dr Allen is now able to provide appointments via Zoom, and that I can arrange these appointments with him directly.  This is extremely convenient.

I would highly recommend him!

Dr Danny Allen was extremely helpful in diagnosing my ADHD and was highly knowledgeable on the subject, picking up on specific traits of mine that I had not initially thought to link to my attention deficit and giving great advice in regards to medication. I would highly recommend him!

I feel I can carry on with my life again

I had a very successful outcome after being treated by Dr. Allen. I was in desperate need of help as I felt I was verging on a mental breakdown. I was also seen within 2 days of being referred by my GP which is amazing. I feel now as if I can carry on with my life again.

I cannot thank Dr. Allen enough

I was incredibly nervous prior to my initial appointment with Dr Allen but from the moment the lady helped me find the clinic door my mind was put at rest. I feel positive following my treatment with Dr Allen and can not thank him enough for the changes he has made to my life.

Dr Stoffel is one of the UK’s leading authorities on rTMS

I have known Dr Stoffels for around 6 years and have first-hand experience of her expertise in running a mental health practice. Being one of the first practitioners within the UK to implement the use of Repetitive Transcranial Magnetic Stimulation (rTMS) for a number of conditions including depression and memory disorders, Dr Stoffel’s is one of the UK’s leading authorities on this particular treatment platform. I have always been impressed by Dr Stoffel’s professionalism and ability in offering tailored treatments to meet the needs of each individual patient

The feedback I got from patients treated by Dr. Stoffels was always positive and glowing

I first met Dr.Stoffels 3 years ago as a Physiotherapist in Burton Park hospital. Dr. Stoffels is a very humble individual who gets along very well with her peers and patients as well as the clinical team.

I was always very impressed with Dr.Stoffels's ability to handle stressful situations and get patients to relax when others could not. Her professional approach,ethos and passion definitely helped to increase the hospital 'success rate.

Dr.Stoffels has an exceptional sense of responsibility and that has caused her to spend consecutive days here at the hospital caring for patients. Her medical experience and clinical knowledge allowed her to work with patients of all ages and all neurological conditions and her effectiveness knows no bracket. The feedback I got from patients treated by Dr.Stoffels was always positive and glowing.

Dr Allen’s diagnosis and subsequent treatment has been nothing short of life-changing

I couldn’t be happier with the care I have received. I have been listened to and understood and Dr Allen’s diagnosis and subsequent treatment has been nothing short of life-changing. I am thriving in my job instead of feeling overwhelmed and the improvements to my marriage and my relationship with my children have been beyond what I had hoped for. Dr Allen 1, ADHD nil, I’d say. Thank you so much for turning down the volume so I can start living my life again. Male, Buckinghamshire

Dr. Allen has had the biggest impact on my health and well-being

I want to thank you for your knowledge, help and prescribing these two excellent drugs, as it's really made a very positive impact on my health and well-being - the biggest impact any doctor has managed yet.

Dr. Allen is a very caring doctor

I would like to thank Dr Allen for the support he has given me and my husband in the few times we have seen him. We have seen him at very emotional times for us and his support has helped us very much. I think he is a very caring doctor and this is shown with the attention he reminds his patients of the appointments or the fact that he checks on the status of his patients. This is important for me as I never felt alone. I would not hesitate to recommend Dr Allen to anybody for his medical expertise but also for the way he has treated me and my husband who came with me to some of the appointments.

I have never felt so comfortable, open and honest with a psychiatrist before

I was diagnosed with bipolar disorder six years ago. I benefitted from NHS and private psychiatric care in Oxfordshire for four years, before moving to Beaconsfield where I was referred to Dr Allen. Now, aged 32, I have never felt better. I attribute that in largest part to Dr Allen’s professionalism and experience. To give a flavour of his methods:

Dr Allen has true expertise; he is authoritative but quietly unassuming in his approach. Dr Allen establishes a strong and genuinely empathic doctor-patient relationship that is based on mutual trust. I have never felt so comfortable, open and honest with a psychiatrist before.

Dr Allen is also extremely patient, almost subtle in his approach. Patients are rarely surprised when they are first diagnosed - after all, it is your life history - but then what? Mental illness is a difficult thing to accept because it trespasses on your (subjective) perspective of who you are. Acceptance means coming to terms with the objective prognostic nature of the diagnosis and its treatment. It took me years to get to that stage.

Dr Allen maintained his patience and he acted as the voice of reason - that is no small comfort during a transitional period when you cannot always trust your thoughts. Bipolar disorder did not define me; but I accepted it at last.

Finally, the search for the most appropriate treatment(s). This can be a frustrating process - we are all different and there is no substitute for trial and error. Dr Allen communicated his strategy clearly and he was only too happy to involve me in the decision making process, which included making appropriate dosage adjustments based on my feedback as a medication-sensitive individual. Not only is that degree of personalised care a rarity, it was also very clever: it empowered me; it gave me some degree of control over my treatment; I willingly complied and my condition improved markedly as a result.

I have never looked back and I wholeheartedly recommend him.

Dr Stoffels’ positivity has enabled real successes to be achieved for her Patients

I have always witnessed Dr Stoffels having a compassionate Patient centred approach together with the skill of listening, both with her Patients and their families, never avoiding those sometimes difficult conversations but always considering the emotion and wellbeing of those she is speaking with. As a Mental Health Advocate I welcome a Consultant having an open door policy, Dr Stoffels has always afforded me this. Welcoming questioning and discussion to both find a way forward for the wishes of her Patients and the Medical need.

Dr Stoffels positivity has enabled real successes to be achieved for her Patients largely in line with their wishes and always in their best interests. Dr Stoffels in my experience is both a credit to herself and the Mental Health / Acquired Brain Injury Profession.

I look forward to Advocating for Dr Stoffels Patients long into the future.

A highly respected expert in her field

Dr Martine Stoffels is a much valued colleague and a trusted and highly respected expert in her field and, very importantly, always a pleasure to work with.

Appointments are now available online via a fully secure platform - and thus accessible to all.

In my professional opinion, a safer pair of hands in the specialist field of psychiatry and mental health, especially in our shared special interests of acquired brain injury, dementia and neurobehavioral disorders, would be very tricky to find.  It gives me great pleasure to recommend Dr Stoffels, especially at this current time when the need for this type of expert care is so great.
