Dr. Erwin Lingenfelder

With Hatmed approaching 25 years it has been a privilege to see it grow from a small but dedicated practice to where it is now: a fully-fledged medical centre offering a host of facilities all designed to make the experience for our patients as pain-free as possible. As we near that milestone it is particularly gratifying to work with a new generation of doctors and share ideas with them. I am extremely 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 in our beautiful country. I am a keen mountain biking novice. I like nothing more than a home-cooked meal with my family or friends, and on weekends you are sure to find me at my braai!

Dr. Johan Momberg

I qualified as a medical doctor at the University of Pretoria and then traveled abroad to spend 6 months working in England. After returning to South Africa, I went into private practice and became one of the founding members of Hatmed during 1995. I am 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 particular 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 have 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 did 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. During 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 bring 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 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 pediatrics but enjoy working with people of all ages.

I love spending time with my beautiful wife, family and friends and enjoy preparing food with them and watching sports. Interacting and learning from people of different cultures excites me and I love to travel yet I 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 Res. In 2010 I had the privilege of being Primaria of House Curlitzia.

After graduation, I did my 2 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 am passionate about using the medical profession to impact on the youth of today and strive to be a positive influence to 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 (Dentist)

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 am 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 are reading, photography, crossword puzzles and sewing. I have 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)

Elaine 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 traveling, meeting new people and my other great passions are food and music. I also enjoy spending time in the outdoors cycling, running and swimming.
