Dr David Zemmel

My medical training was undertaken at Trinity College, Cambridge University for my first three years and then I moved to London to complete my studies at Royal Free and University College Medical School. Following medical school I worked in junior hospital doctor posts in a variety of specialities. This has given me exposure to a wide range of clinical challenges and experiences and this has fueled my ability to be a General Practioner. I have worked as a doctor in, Accident & Emergency, General Surgery, General Medicine, Orthopaedics (Bone surgery), Obstetrics and Gynaecology, Paediatrics (Children’s medicine), Dermatology (skin), Genitourinary Medicine (I worked in a sexual health clinic) and Psychiatry.
My title is Dr David Zemmel MA MBBS DRCOG MRCGP.
MA and MBBS refer to my medical school degrees, from Cambridge University and Royal Free and University College Medical School
DRCOG refers to a Diploma of the Royal College of Obstetricians and Gynaecologists – I have these letters as I’ve passed an exam, which means I’ve undertaken extra training in obstetrics and gynaecology. MRCGP means that I’m a member of the Royal College of General Practioners – I have these letters as I gained a Merit award in an extra exam which tests a wide range of areas required to be a General Practioner in the UK.
As well as having the required diversity of knowledge and skills required to be a GP, I also have specialist training in certain areas. I am the clinical lead for the Attenborough Surgery’s Anti coagulation Monitoring Clinic. This means that I’m the doctor who manages the running of our clinic for monitoring the blood tests of our patients who are required to be on warfarin. I also provide regular cryotherapy sessions at the surgery; this means that I see patients with certain lumps and skin lesions which can be “burnt” off using a liquid nitrogen spray. Patients who have skin lesions appropriate for this clinic, will be referred to it by me, or one of my GP colleagues.
Away from the surgery, I enjoy spending time with my wife and three young children. I also try and keep as fit and active as I can through regular sport and exercise. Sometimes, I even manage to cycle to and from the surgery and have been known to do the odd home visit by bike.

Dr Zanne Lewis

My medical training was undertaken at University College London Medical School. I was on the Barnet Hospital Vocational Training Scheme and have worked as a doctor in Accident & Emergency, General Medicine, Surgery, Paediatrics, Obstetrics & Gynaecology and Psychiatry. I therefore have lots of experience in a wide range of clinical areas. I have also undertaken extra training in Obstetrics & Gynaecology and Paediatrics and have achieved a diploma in both these areas.
I have worked as a GP in Hertfordshire for over 5 years prior to joining Attenborough and do regular out of hours sessions for Herts Urgent Care. Away from the surgery, I enjoy spending time with my husband and 2 young daughters.

Dr Sandip Pramanik

I joined Attenborough Surgery as a GP Partner in October 2013.
I completed my medical training in 2008 at the University of Manchester. Following this I worked in various posts as a junior doctor at University Hospital Birmingham and then City Hospital.
Over the last 3 years of my GP training I have worked in Paediatrics, Accident & Emergency, General medicine, Acute Medicine, Obstetrics & Gynaecology, Elderly care and Intensive Care. Much of this has been in Watford General Hospital and I have worked with many of the local Consultants of these specialties. I have also worked as part of the Community Mental Health team and worked on call with psychiatric emergencies in the neighbouring units in Hertfordshire.
In addition to my hospital jobs I have already worked at Attenborough surgery for over a year as a GP registrar. I have a particular interest in Child Health, General Medicine and Psychiatry. I have also undertaken a BSc in Biomedical Science and a Masters degree in Immunology and hold a strong interest in research and academic medicine. To further my interest in child health I have recently completed the Diploma in Child Health.
Away from work I enjoy playing badminton, golf and cricket and like spending time with my family and friends. I also do charity work and act as a mentor to young aspiring doctors.
