Medical Doctors at Hatmed

Dr. Erwin Lingenfelder

With Hatmed approaching 27 years, it's been a privilege to see it grow from a small but dedicated practice to where it is now. Today, Hatmed's become a renowned and fully-fledged medical centre offering a host of facilities, all designed to make the experience for our patients as pain-free and comfortable as possible.

It's been particularly gratifying working with a new generation of doctors, sharing ideas with them and finding new ways to augment our patients' experiences. I remain positive about South Africa's future, a fact which is endorsed on a daily base working with our future leaders.

On a personal level, I love travelling through our beautiful country. I'm a keen mountain biking novice. I like nothing more than home-cooked meals with my family and friends.

Dr. Johan Momberg

I qualified as a medical doctor at the University of Pretoria, then travelled abroad to spend six months working in England. After returning to South Africa, I went into private practice and became one of the founding members of Hatmed in 1995. I'm a family physician, with a special interest in immigration, pre-employment and executive medicals.

Inspired by my love for travelling and my knowledge of travel requirements, I started Hatmed Travel Clinic. I have a interest in travel medicine and have been a member of The South African Society of Travel Medicine since its inception.

A keen sportsman in my spare time, I completed the Comrades marathon, Argus and 94.7 cycle tours. I've also taken part in various mountain bike races and have summited Mount Kilimanjaro. Another great personal passion is cooking. I love to try out adventurous new dishes and to explore the potential of my pizza oven.

Dr. Engela Niesing

Growing up on a Northern Cape farm, I developed a love for the outdoors, cooking, crocheting and, of course, a good old-fashioned braai. Early in high school, I developed an interest in medicine. I completed my first aid training during this time and offered first aid for all the sporting events in town. After matriculating, I studied medicine at the University of Stellenbosch.

After my MB ChB graduation in 2012, I did my internship at the very busy Leratong Hospital in Krugersdorp. During my two years at Leratong, I had the opportunity to work in most medical disciplines, including surgery, family medicine, internal medicine, obstetrics and gynaecology, paediatrics, anaesthesia and orthopaedics.

Throughout 2015, I completed my community service at 1 Military Hospital in Pretoria, working initially in casualty before moving to anaesthetics. I have a keen interest in family medicine and enjoy the diversity that working with people brings to my life. In my private time, I enjoy travelling with my husband, golfing, outdoor activities, visiting with family and friends or just some quiet time with my husband and our two Scotties.

Dr. Blessing Thusi

I qualified as a medical doctor at the University of KwaZulu-Natal and moved to Johannesburg to start my medical career in an internship at Charlotte Maxeke Academic Hospital-Johannesburg General Hospital. My community service and Medical Officer years were spent in Vereeniging, from 2010.

My passion for clinical medicine grows daily as I view the medical profession as a crucial part of my life. I have a keen interest in paediatrics but enjoy working with people of all ages.

Nothing makes me happier than spending quality time with my beautiful wife, family and friends, and I enjoy preparing food with them and watching sports. Interacting and learning from people of different cultures excites me, and I love to travel yet still believe that we live in the most beautiful and diverse country in the world.

Dr. Eliz-Mari Delport

I qualified as a medical doctor at the University of Pretoria in 2013. I enjoyed being a student at Tukkies and have only the fondest memories of my time on campus and in residence. In 2010, I had the privilege of being Primaria of House Curlitzia.

After graduation, I did my two-year internship at Chris Hani Baragwanath Academic Hospital in Soweto, Johannesburg, and will always be thankful for the amazing training I received there. I returned to Pretoria in 2016 to do my community service at Tshwane District Hospital, where I worked in the HIV clinic. During this year, I also completed my Diploma in HIV Management.

I'm passionate about using the medical profession to impact positively on the youth of today and strive to be a positive influence on young minds. I love being part of a profession focused on helping others lead healthier and happier lives.

In my personal time, I enjoy spending time with my family and friends.

Dr. Annette Preis

After graduating from the University of Pretoria as a dentist, I initially worked at clinics for the Department of Health. I then became a lecturer at the University of Pretoria, where I did an Honours degree in Dentistry and a Diploma in Tertiary Education. I had my own private practice, which I later sold to spend time with my two sons while working part-time.

For years, I was part of the team at a medical centre and enjoyed the interaction with my medical colleagues. I'm a family dentist and like to get to know my patients better while treating patients of all ages. At home, I like to be adventurous in the kitchen with new recipes.

My hobbies include reading, photography, crossword puzzles and sewing. I've written and edited primary school handbooks, travelled abroad and to neighbouring countries and done off-roading. I love nothing more than spending time with family and friends, and when on holiday, visiting and exploring little towns and places.

Elaine Viljoen CA (SA)

I qualified as a Chartered Accountant at Deloitte in 2012. While working for Deloitte, I was exposed to a wide range of industries, and I also had the opportunity to gain international exposure when I briefly worked for Deloitte in Chicago, USA.

Thereafter, I gained experience as a Financial Manager in the micro-lending industry, and as a Financial Accountant in the advertising, media and information technology industries. I love travelling and meeting new people, and my other great passions are food and music. I also enjoy spending time outdoors cycling, running and swimming.
