Continuing Your Care After the Retirement of Dr Ken Wong
A message for patients transitioning to the care of Dr Peter Hamer
We would like to extend a supportive message to patients who were previously under the care of Dr Ken Wong.
After many years serving the Central Coast community, Dr Wong has now retired from surgical practice. To ensure his patients continue receiving safe, high-quality and uninterrupted care, all bariatric and upper-gastrointestinal patients will now be supported by Dr Peter Hamer, an experienced Upper GI & Bariatric Surgeon based in Gosford.
Our entire team is committed to making this transition smooth, comfortable and fully supported.
You will continue to be offered the same high quality surgery, in the same locations (in person or telehealth) at the same pricepoints as Dr Wong has always offered.
