John Wang

Dr. John Hsiang-Yeou Wang, MD

General SurgeonCritical Care Specialist


John Wang, MD, is a top surgical oncologist specializing in minimally invasive approaches, with a focus on upper gastrointestinal and hepato-pancreato-biliary surgeries. He has been named a Castle Connolly Top Doctor since 2017.He earned his medical degree at University of Maryland School of Medicine and completed his residency at St. Vincent’s Catholic Medical Center. He completed four fellowships, including two in minimally invasive surgery, surgical oncology and surgical critical care. Dr. Wang’s extensive background reflects his intense passion for offering patients only the very best care. “My job as a surgeon is to be a sponge—to absorb, learn and grow,” he says. “I’ve been exposed to a wide variety of techniques, and I’ve incorporated them all along the way.” He enjoys figuring out solutions for the most complex cases and continuing to build his knowledge for every future procedure. Dr. Wang is one of only a few surgeons at Northwell who can treat right-sided colon cancers by using a suprapubic approach, which leaves no visible incision on the patient’s abdomen, offering better cosmetic outcomes. He has trained his surgical partners on the approach as well, noting the importance of working together as a team and sharing knowledge. “Each member of my surgical team brings a different set of experiences to the table,” he says. “For our most complex cases, two sets of eyes and four hands is better than one set and two hands.” Dr. Wang sees this group effort as vital to the patient’s care and experience, which are his topmost priorities. “When you see a patient doing well after a successful operation, that’s better than doing the operation itself,” Dr. Wang says. “It’s the most satisfying feeling in the world.”

Data Transparency and Trust: Understanding WebMD Doctor Listings and Reviews

We know that finding the right doctor or provider is important to your health. That’s why we want to ensure you have confidence in the provider profiles and listings you see on WebMD Care. Our provider data is sourced from the physicians themselves as well as publicly available databases. Any doctor or provider who claims their profile by verifying themselves can update their information and provide additional data on their specialties, education, accepted insurances, conditions they treat, and procedures they perform.

All the physician and provider reviews on WebMD Care are provided by users just like you. Knowing these reviews provide insight into how other patients feel about a doctor, we maintain internal policies and protocols to ensure the quality and accuracy of all reviews. Providers are not able to remove or modify reviews on their own. Reviews can only be removed after an internal review by our customer service team.

We value your input and encourage you to reach out to our support team if you encounter any issues.
