Consultant obstetricians

Dr Aamna Ali

Dr Aarthi Mohan, MRCOG, PhD

Dr Johanna Trinder, RFCOG

I am a consultant obstetrician with expertise in maternal medicine. I qualified in London 1990, moved to Bristol in 1994 and took up my consultant post at University Hospitals Bristol in 2003, in obstetrics and maternal medicine.

I hold an honorary senior lectureship at the University of Bristol and I am a fellow of the Royal College of Obstetricians and Gynaecologists. I am a member of the MacDonald Obstetric Medicine Society, the British Maternal Fetal Medicine Society and secretary of the UK Maternal Cardiology Society, since its foundation in 2019.

I have a long term interest in education, hold the diploma in postgraduate medical education and have organised numerous local, regional and national maternal medicine teaching events. I am also head of school for O&G Postgraduate Education South West-Severn and am a qualified coach/mentor, holding the Institute of Learning and Management level 5 certificate in coaching and mentoring.

I have developed and led the tertiary maternal medicine service at UHBW over the past 19 years and set up the Regional Cardiac Obstetric Network ft in 2005, which was the first of its kind in the UK. I have been invited to lecture and teach at many national meetings and courses. I keep my knowledge up to date by attending national and international meetings and am involved in contributing to, and reviewing national guidelines on management of pregnant women with medical problems. I have published research in the field of maternal medicine, predominantly on the subject of heart disease in pregnancy.

Outside of work I spend my free time dog-walking, gardening, sailing and seeing friends.

Dr Rebecca Simms MD, MRCOG, DFRSH, MBChB

Consultant in obstetrics and maternal-fetal medicine. I have been a consultant in obstetrics and maternal-fetal medicine at St Michael's Hospital, University Hospitals Bristol and Weston, since 2015. Prior to becoming a consultant, I trained in obstetrics and gynaecology and then completed my subspecialist training in maternal-fetal medicine (SST MFM) in the Severn postgraduate deanery.

I have been the lead obstetrician for haematology since becoming a consultant and I am a member of the British Society for Haematology Obstetric Haematology Special Interest Group.

I work very closely with our obstetric haematologist and colleagues at the Bristol Haematology and Oncology Centre. As our Trust is the tertiary referral centre in the South West for haematology, I am closely involved in managing women from across our region with an extensive range of haematological conditions as part of our experienced multidisciplinary team.

I am also the South Bristol Obstetric Academy lead for the Reproductive Health and Care of the Newborn (RHCN) course, a part of the University of Bristol's medical undergraduate degree.

Specialist midwives

Hannah Collins - Maternal Medicine

I qualified as a midwife in 2016, and worked in South Devon until moving to Bristol in 2017.

I have worked in many different departments including Central Delivery Suite, Antenatal/Postnatal Ward, Transitional Care Ward and the Midwifery Led Unit.

I have worked as a core midwife on the antenatal /postnatal ward since late 2019, and still do part time. I started this role as maternal medicine specialist midwife in April 2022.

I have a special interest in women who have medical conditions, how this affects their pregnancy, and vice versa. I attend our maternal medicine clinics and will see women who are admitted to the antenatal/postnatal ward on our daily ward rounds.

Vicky Fisher - Diabetes

I've worked at St Michael's hospital as a full-time midwife since qualifying from the University of Worcester in 2005. I've gained a wealth of experience caring for women during pregnancy, birth and the postnatal periods, both in hospital and at home. I believe it's important to get to know women and building meaningful relationships throughout pregnancy, so particularly enjoyed my years as a community midwife. I studied diabetes in pregnancy at Warwick medical school and have held the post of diabetes specialist midwife since 2018. I work closely with obstetricians, diabetes nurses and endocrinologists to provide care for pregnant women with all types of diabetes.

Lisa Boyce - Diabetes
