I give Dr Sebastian Kwon a ⭐️⭐️⭐️⭐️⭐️ and more. He is the best and most compassionate specialist doctor my husband and I have met. We have recommended him to our friends and relatives who needed help with his specialisation and we're proud to say, the one's who've been under his care were very happy too. I saw him again yesterday, 28th May 2025 in his new room at Nepean Private Hospital, and he has nor changes, still compassionate and the best. Thank you very much for your help Dr Kwon. May God bless you and your family more and protect you all always🙏🙏🙏

I saw Dr Kwon at his Penrith rooms and at Penrith Private Hospital. I found him to be engaging, informative and easy to talk to. He explained my up coming hernia surgery very well and shared and explained my completed surgery along with photos taken during the surgery. I would thoroughly recommend Dr Kwon to anyone considering similar surgery.

Dr Kwon has an excellent bedside manner and I was so lucky to be operated on by him. I had an emergency gallbladder operation at Norwest Private hospital so had no choice in choosing my surgeon. He was very caring and explained everything he was doing so well. I am so grateful for his expertise and would recommend him.

Dr Kwon is a very professional practitioner. He explained my procedure to my satisfaction and he was able to allay any concerns I had. The operation went smoothly and I didn’t experience discomfort. I met an ex-patient of Dr Kwon in Penrith before my procedure and she was full of praise for Dr Kwon’s work. Dr Kwon is a gentleman with a good sense of humor and I can heartily recommend him to anyone who may require his services. Michael Childs -Blaxland NSW . March 2025

I had x4 (count ‘em), hernias repaired in 1 sitting January 2022 by Dr. Kwon, and I couldn’t be more grateful for his skill and expertise. 3 years later, I haven’t had a single issue, and the keyhole surgery through my belly button barely left a scar. The precision and care Dr. Kwon and his team demonstrated throughout the process made all the difference in my recovery. I feel truly privileged to have been in the hands of such a talented surgeon.Highly recommend! Thank you Dr. Kwon!!!

I’m lucky in the fact I’ve been in good health for all my life. I don’t even have someone that I’d call ‘my doctor’. That said I lifted a heavy object and suffered a hernia as a result. A visit to a local GP saw me get a ‘highly recommended’ referral to Dr Kwon. I could understand why after I met him. He explained every detail of why it happened, how it will be corrected and what I can expect along this short journey. Like I said, I don’t have much experience with these situations but this whole process was like a Swiss watch. I could not fault the any of process and extremely grateful with my now full recovery. 10/10. Dr Kwon is a true professional and I’m so glad to have been in his care.

Called Dr. Kwon’s practice last Friday and was told there was an opening for a consultation that day. Dr. Kwon was extremely meticulous in diagnosing and articulating my medical history. He took a great deal of care in establishing the context, problem and solution. By the end of the consultation, I knew exactly what my problem was and what the surgical requirements were. Importantly, I knew I was in capable hands.I had my surgery shortly after. Everything went smoothly. I was impressed with how quickly everything was arranged, and how little the entire process impacted my life. I’m back to work now, only a week later.Of course, the timing of my experience may have been unique, but I think it’s a testament to the practice and their experience to be able to deliver such quality outcomes in a limited amount of time.Thanks Dr. Kwon!

In my experience with Dr Kwon, I found him to extremely professional and well versed in his medical field.From the initial consultation to post surgery, I was always kept updated with my progress. I had Laparoscopic surgery for a inguinal hernia and after 6 weeks I can barely see the scars.I would recommend Dr Kwon with full confidence.

I was referred to Dr S Kwon for my GI related issues through my ENT specialist. I am glad I trusted his recommendation and went ahead with hiatus hernia repair surgery. I want to express my gratitude to Dr Sebastian Kwon for treating me with my medical procedures in June, July 2023 and subsequent follow up gastroscopy in August. He is very thorough and confident of his analysis, especially the pre and post process of providing a detailed consult or op report unlike other specialists surgeons that I have been to.Dr Kwon is indeed an experienced GI surgeon and I would highly recommend him to anyone looking for a specialised laparoscopic surgery.Also, thanks to his former reception team Kim and Fanny.Patsy

My introduction to Dr Kwon was due to an urgent gall bladder removal surgery that I needed to undergo. I am grateful he was able to accommodate me despite his packed schedule. He walked me through the process and in a matter of hours, the surgery took place. I must mention this is not my first laparascopic surgery and I can say Dr Kwon’s technique is clean and impeccable!It is also worth mentioning that his Medical Receptionist, Sunni, is so lovely, accomodating, and genuinely cares.

I had a large hernia repair with associated muscle separation. From the first consult Dr Kwon was able to put mind at ease. He discussed the options available for repair. I eventually decided on the best course of action from the detailed information provided . This included photos and other important details. The operation took place at Nepean private. The operation was effective and will allow me to continue working in a heavy industry, without fear of recurrence or pain of a new hernia. I could not be happier with the outcome of the operation.

Our mum Carmen Xiberras recently underwent a major large Hernia keyhole surgery (2). From the beginning Dr Kwon has been so thorough and has shown the highest level of professionalism and throughout this entire process he has continually communicated everything exceptionally well to our 79 year old mum, my sister and I. He is very welcoming and easy to understand and explains what to expect after surgery...Sunni, his secretary has also been patient and fantastic in taken my calls. She is very knowledgeable in her field and will always return our calls and check to see how mum is progressing. She is so lovely and thoughtful. Mum and I appreciate this very much and thankyou for this service Sunni...The Xiberras family can not thank Dr Kwon enough for everything he has done for our elderly mum and we would highly recommend him for Hernia surgery to absolutely anyone that needs him.Best Wishes and may God bless you always and your wonderful work.Carmen Xiberras and her 7 children...xxxx

Look, major surgery is no-one's favourite recreation, but if you need abdominal surgery, Dr Kwon is a top choice.The first reason is that he is very approachable, has a great sense of humour, and is extremely thorough in explaining what is needed, why, and how he will do it. For me, it meant I went into the surgery confident he knew what he was doing, and would do it in the best way. That trust is essential: for peace of mind, you need a surgeon you have confidence in - after all, you are trusting them with your life.But the most important reason is that he is a really good surgeon. I needed a double hernia repair (turned out I had had them for quite a while; I'm almost certain I can recall when I tore one, over 60 years ago). Since I had had two previous major abdominal surgeries for other issues, Dr Kwon was expecting the worst in terms of what he would find. He wasn't wrong. There were adhesions all over the place from the previous surgeries (I have the photos to prove it). What would normally be a half hour surgery took over one and a half hours. That must have taken immense concentration: one and a half hours where a single wrong move could be fatal. Thankfully, he did it. And he did it for a fixed fee, despite knowing ahead of time that this was probably what he was facing.The results are amazing. You expect some pain and debility after surgery, but it really wasn't much. I didn't need or use any painkillers after the surgery, and slept fine that evening. I did have a couple of paracetamol the following morning - for my arthritis! I'm in my 70s, yet I was able to do a kilometer walk the afternoon of the following day, and 5 kilometers in hilly country the day after that. It confirms that Dr Kwon had done an amazing job, despite the complications, in minimising physical trauma. Six weeks later, I feel fitter than I have in 20 years. In fact my biggest problem is remembering that I still have limitations, and not to lift more than 10Kg (Dr Kwon's schedule goes up to 20Kg in a couple of weeks, which will be a bit easier to remember).Added 2024: now a year later, I'm back to full duties, including construction, on our bush block. That involves carrying 40Kg items around on a steep block, shovelling hundreds of kilos of earth, etc. I have had no problems at all with the hernia surgery.Dr Kwon has my very strongest recommendation. You may, if you are very lucky, find his equal, but I really doubt you will find anyone better, no matter how hard you search.

GWS Surgery is a great facility. It is modern, clean and has off street parking. The receptionist there was helpful, caring and the waiting room was not packed out with other patients. Saw Dr. Kwon there twice, each time without any major issues.

I recently had a gastroscopy and colonoscopy performed by Dr Kwon. Thankfully all went well and no issues were identified. Dr Kwon has carried out these procedures for me in the past, as well as the removal of my gall bladder a few years ago. In every case he was professional and pleasant to deal with, explained what was happening and answered all my questions. My post op recoveries have been good and I’m sure this has to do with Dr Kwon’s surgical abilities. He is a likeable man who genuinely cares for his patients (and is clearly a very good surgeon). I would be happy to have Dr Kwon treat members of my family and so I am happy to recommend Dr Kwon to anyone looking for a great GI surgeon.

Dr Kwon is an excellent practitioner. He is very welcoming and understanding and listens plus explained in detail what is happening and why. He followed up on everything he said he would do and provided outstanding documentation after ever consult / procedure so we always knew exactly what was happens and what the results were. I had my Gallblander removed by Dr Kwon, it was hassle free experience and he arrange everything in a very short space of time, I went home the same day and had basicly no pain or side effects and he followed up to make sure everything was fine. Dr Kwon had an amazing bedside manner and alway made me feel comfortable. I was so happy with his service that I had him look after my wife who is extremely ill due to cancer, he expedited her procedure due to urgently and went out of his way to assist, Dr Kwon communicated and consulted with other specialists who were looking after my wifes care and made sure he and everyone else knew exactly what was happening. Dr Kwon at every stage showed a level of care which I find is rarely seen. Thanks Dr Kwon.

Dr Kwon and his staff were fantastic. Very professional. Always willing to answer and questions I might have. My initial consultation was brilliant as he helped out my mind at rest about a potential issue but continued to offer to do an investigative gastroscopy and colonoscopy to help alleviate anxiety and give the all clear. His reports were well documented and follow up was prompt and professional. A pleasant manner and easy to relate with. Would recommend!
