Bio

I am a Consultant Psychiatrist with over 20 years of experience in psychiatry, including more than 10 years working as a Consultant Psychiatrist for the NHS. I provide compassionate, personalized care for adults experiencing a wide range of mental health difficulties such as depression, stress and anxiety, ADHD, bipolar affective disorder, schizophrenia, and personality disorders.

I have completed my BSc, MBBS medical degree, MSc, and PGCMedEd at University College London (UCL) and undertook my postgraduate psychiatric training in North London. I obtained my Membership of Royal College of Psychiatrists (MRCPsych) and gained my CCT in General Adult Psychiatry, as well as having Section 12 approval from the Secretary of State. I have been working for the East London NHS Foundation Trust for over a decade as a Consultant Psychiatrist in both the community and hospital, and also hold positions such as Undergraduate Lead and Inpatient Ward Lead Consultant.

My approach is collaborative and evidence-based, combining medication management with psychoeducation and other treatment modalities to promote recovery and resilience. I believe that understanding is the first step toward lasting change, and I take time to ensure my patients feel informed, heard, and empowered throughout their care. Alongside my clinical work, I’ve published and presented internationally on psychiatric education in conferences, reflecting my ongoing commitment to improving understanding and outcomes.

I had the best experience with My Doctor. She has been kind and professional in every aspect. She was able to understand my current situation very well and I found this appointment very useful. I was able to arrange an appointment so quickly. I would definitely recommend Psymplicity. Thank you so much once again. Really appreciate all the help and time .

Fantastic service from start to finish

The doctor was very kind and patient, I felt well taken care of.

The Dr was really calm and attentive which put my son at ease, which created a sense of trust between them. The Dr explained things very clearly. Would highly recommend Psymplicity

Very happy. The consultant was excellent.

We had a good meeting with my Doctor who is always very helpful and understanding. Efficient service. Thank you again for all your help.

My Doctor was very helpful and we felt all our questions were answered.

My Doctor is an amazing doctor- I always feel so listened to and looked after by him. I also really value the service you offer at Psymplicity from the admin staff, billing process and the different length of appointments you offer.

Nothing to say, all went as I'd hoped, My Doctor is great.

Service has dramatically improved over the last couple of months.

My doctor is amazing, he's change my life so much, he's a really good dr, and shows he cares so much better than the NHS and worth every penny! He's always been amazing.

Again a fantastic service

Excellent. Professional all of them

Well, it's been an expensive experience, obviously - but has so far has been worth the money:)

A methodical approach, understanding everything clearly and talking us through next steps. Admin was also really helpful in sorting out the appointment.

Excellent quality service, outstanding patient care

Very professional highly recommended. I felt at ease and relaxed and under no pressure.

Very pleasant from start to finish. Can’t fault them at all.

All round excellence especially from my Doctor

As always, I am really pleased and impressed with my Doctors empathetic, understanding, sympathetic attitude and clinical expertise.

I felt listened to and found my consultation / ADHD adult assessment really beneficial for my mental and physical health. I am going to put some of my Dr’s advice into practice.

The Dr would like me to send her a written account of my experiences living with ADHD. I am pleased I have had the assessment and consultation as it has helped me to understand my neurodivergent brain and to lose some of the awful shame I felt about never being good / competent/ intelligent enough.

I was very impressed with how I was professionally and non judgementally assessed. I felt valued and listened too.

I cant put in to words how greatfull that I am from speaking withmy Doctor. She has been absolutley amazing with everything & I cant thank her enough even speaking with my sister & coach getting my background and knowing me in as little as 2 hours.

I always find Psymplicity to consistently provide excellent, professional and prompt treatment and response to any queries.

The entire team, from the admin and accounts staff to the wonderful doctors who always go above and beyond to ensure your concerns are met with compassion, understanding and empathy which goes a long way

Thank you to all the brilliant team; I will continue to recommend Psymplicity to all family and friends who require medical care and have done so already, being a patient for 6 years myself.

Very professional and quite life changing

Very pleasant experience. Good communication and comprehensive information provided before and during appointment.

Brilliant service. Quick to be seen. Thorough approach. Wonderful service by everyone involved throughout.

My doctor was was brilliant!!!

Really smooth process, easy to follow. Really great clinician, very understanding.

Recently I decided as recommended by a friend to have a ADHD assessment. Much to my amazement I was diagnosed with ADHD. My whole life suddenly felt very normal for the first time in what felt like forever.

I cannot thank Psymplicity enough. I was coming to the end of my tether. Psymplicity has helped me more than i thought possible. The knowledge alone has been a life changing experience for me. Hopefully can further my career without my ADHD holding me back.

Very efficient and easy to book, super quick to get an appointment

The psychiatrist I spoke to made me feel seen and heard for the first time in my life. I always felt like an oddball when explaining my symptoms to a g.p. Yet, today I was made to feel understood. I cannot thank him enough for his help today. To realise it wasn’t all because I was a bad kid, it was because I have autism and a.d.h.d. Has made me feel compassion towards myself instead of shame.

The process was so straightforward and simple. I wish I had done this sooner. All the years of anxiety and feeling different, changing myself to fit with people. I could cry with relief. I've suspected for years but still doubted that an assessment/diagnosis would clarify things, more just say I needed to concentrate or pay attention. However, it explains everything and I feel freed and validated for the first time in my whole life.

Very professional admin team that answered my numerous questions over the phone with understanding and patience. Would recommend to any individuals seeking psychiatric help.

It was a review appointment with my Doctor following 6 months shared care. As always the appointment is informative and helpful. My Doctor has helped make a huge difference to my life. So glad I’ve had his continuous care over the last 18 months. It’s been worth the initial teething problems with Admin at the practice. Which also seems to have improved.

From start to finish everyone has been so lovely and kind. Couldn’t ask for a better service

Really easy to book and great communication leading up to the appointment and very friendly and professional Doctor, felt at ease very quickly and he was so kind and reassuring.

Very professional highly recommended. I felt at ease and relaxed and under no pressure.

Good service and helpful staff, thank you

Very happy. A business that recognises existing diagnosis rather than trying to screw as much money out of one as possible. Very pleased.

My doctor is a thorough and approachable practitioner - I feel utterly heard and have time to ask questions etc.

I had a very good all round experience, very professional.

Easy to get appointments with excellent professionals

My doctor was amazing to speak to, he very often explained how things may make me feel and the explanations were incredibly accurate. Many thanks to him

It was great

After 15 years of suffering and being misdiagnosed, finally had a psycatrist who listened to my needs and was able to offer me the best advice. I’m looking forward to being able to start my journey

Really thorough assessment with a very kind and understanding psychiatrist. Can’t fault the service so far.

Absolutely amazing

very happy & felt well listened to and was given plenty of time to talk

Very positive and great experience

Efficient supportive admin, excellent Doctor - wide ranging conversation and advice.

I had a great experience with my doctor, she was very considerate throughout and explained things clearly and concisely.

It was a very valuable experience

Very positive!

Would highly recommend

I was extremely delighted with the consultation and feel confident that I will be able to get the help I need to get back on my feet. Very pleasant and helpful doctor.

I've been using Psymplicity for over a year now. Treatment has made such a difference in my life and they are to thank for it!

I have been a patient at Psymplicity for over 3 years now and I have received nothing short of excellent service from all of the clinical, admin and staff in general.

The team always go out of their way to ensure I can see a psychiatrist when needed, the staff are responsive and the psychiatrist I see, has been extremely helpful in the management of my anxiety and ADHD symptoms, with an extensive amount of medical knowledge and experience.

Very good!

Felt respected and listened too - very grateful

I really wanted to get a straight answer and I finally have!

Really easy experience, my consultant made me feel at ease and I am just very happy to have answers finally. Would recommend

A private psychiatrist company that isn't trying to drag out ti e and milk you for as much money as possible. Really good and they recognise previous diagnosis, which many do not.

An absolute pleasure to deal with from beginning to end. Many thanks to everyone on the team.

Highly recommended. The appointment was well organised, with even a reminder email containing the meeting links on the day. The doctor was polite and considerate and really easy to speak with.

They really help people.

Great follow up contact rom admin and help and advice from my doctor

I contacted them about an adult ADHD assessment. NHS waiting times for adult ADHD in the UK are just unrealistic when you’re searching for clarity about yourself. I had the assessment within a few weeks. Great service.

Fantastic service, very professional and knowledgable. Would recommend this service to any ody

Had no problems with booking, the Dr I see was very nice,pleasant,helpful and honest. Just what you want and need. Could not fault at all. Highly recommended.

Highly recommend. Quick, efficient, empathetic and professional - thank you.

Very professional and useful advice.
