I am so pleased with the results and even more than that, thankful for the positive support and care I experienced from Dr Nietz

Your brilliance and kindness combined in a truly remarkable way. You guided us through the complexities of treatment, offering clarity and instilling hope. Your empathy and unwavering support provided solace during the darkest moments, reminding us that we were not alone in this journey.

Your knowledge and commitment ensured I received the best possible care. Your collaboration with the healthcare team created a seamless network of support, fostering comprehensive treatment and instilling confidence.

Sarah, words cannot fully express the depth of our gratitude. You are not only an exceptional Specialist but also a source of inspiration and strength. Thank you for making an immeasurable difference in my life and being so gentle and caring throughout my journey.

At a very scary, heartbreaking and strange time in our lives we were thankfully pointed in Dr Nietzs'direction. Embarking on the path of a cancer diagnosis with Dr Sarah Nietz and her team was a gamechanger in our familys' journey. Dr Nietz was factual, positive and extremely professional while sharing the road ahead with us in an understandable way. No fancy terminology or sugar coating of the situation.

Every step of the way we had Dr Nietz and the entire team with us, supporting us and just making things happen. Appointments were arranged and information shared throughout.

We could not have asked for a better surgeon, and human to be with us on the road we are on, and we are grateful every day that Dr Nietz has been our go to right from the start. That's why in our house she is known as the King Maker!
