Dr Stephanie Ulmer of Betterlife Surgery, leading Bariatric & Gastric surgeon
in Auckland

About the practice

Surgeon Stephanie Ulmer is the lead healthcare provider at BetterLife Surgery. She is passionate about weight loss surgery and the outcomes that can be achieved for her patients.

Training and experience

After completing her surgical training in 2006, Stephanie gained specialist expertise in Australia utilising many different forms of laparoscopic weight loss surgery.

Upon returning to New Zealand, she was appointed Consultant in General Surgery at Auckland’s Middlemore Hospital where she now treats many conditions – including obesity.

BetterLife Surgery was established in 2008 to provide excellent and specialised private weight loss surgery to those seeking a better life.

Since starting BetterLife Surgery, Stephanie has completed over 300 Bariatric procedures.

Stephanie is New Zealand's only female surgeon currently practicing weight loss surgery.

She regularly travels overseas to ensure that the very best techniques used worldwide are also available to her patients at BetterLife Surgery.

Difficult cases are welcomed - especially those who have had previous weight loss surgery requiring revision.

Stephanie takes immense satisfaction from the life-changing experience that surgery brings to her patients.

“I love Bariatric Surgery and the potential it gives my patients to realise their own potential. For so many people their weight is a major issue - whether this is physical, emotional or both - and it doesn't have to be that way. I love the journey that patients go on with this surgery. From the first consultation through to following up my patients years after their operation it is a privilege to be part of that journey. The challenges are significant, but the rewards are even bigger both for me, as the Surgeon and for
my patients."

Stephanie is married and is the proud mother of 4 young children.

I have been a Registered Dietitian for the past 16 years and started working at Wellington Hospital on the Surgical and ICU wards. I then travelled overseas for 6 years and worked in several hospitals in London in the areas of Bariatrics, Upper/Lower GI Surgery, Gastroenterology, Renal, Diabetes, Haematology, ICU and Hepatology. On returning to NZ I worked as an ACC Dietitian which involved weight management and behaviour change.

Working with people having Bariatric Surgery combines three of my favourite areas of nutrition including surgery, clinical dietetics and behaviour change. I am a non-diet Dietitian and will encourage you to make food choices that support your health while also maintaining your quality of life. I also have three young children and understand the time and energy barriers that can get in the way of good health. I aim to provide evidence based, yet realistic and practical advice to help you throughout the bariatric surgery process.

I love supporting people on this life changing journey and look forward to meeting you at the first appointment!

Jennifer MacDonald

Registered Nurse

I have worked as a Bariatric Nurse Specialist for the last four years. In my role at BetterLife Bariatric Surgery I strive to provide a high standard of care and excellence in a warm, caring, professional environment. I am passionate about my work, with an interest in diet, exercise and the psychology of eating behaviours.

My background is based in Surgical Nursing. I have worked as a Theatre Nurse/Surgical Assistant in the Operating Room specialising in ENT, Head & Neck, Gynaecology, Urology, Orthopaedics, Plastics and General Surgery for 35 years and as an Appearance Medicine Nurse providing Botox, Fillers and Laser Therapies for treatment of vessels, pigmentation and hair removal for the last three years.

I believe these three chosen areas of nursing in which I work complement each other. Although in essence they all provide a physical service. I believe they also improve the client’s mental health by increasing their confidence and self-esteem.

Administration Manager/Receptionist

I am Carmen, receptionist at BetterLife Surgery. For the previous 17 years, while my two sons were growing up, I have run the office of our family business. This allowed me the flexibility to still be a hands on mum while working full time. In the past I have worked in reception, office administration and accounting within New Zealand and in various other countries. I have also worked with both the elderly and with children in teaching and care roles.

As a larger person myself I hope that my previous job experiences and my own personal journey will help to provide you with a safe and comfortable place to start this new chapter of your life.

I genuinely look forward to meeting you on the phone or in clinic and hope to make your time as a BetterLife Surgery patient an easy, enjoyable experience.
