General Surgery
Care Philosophy

Patients should never feel they have to choose between superior surgical skills and warm, compassionate care. As general surgeons, we have vast experience with both traditional open techniques and minimally invasive approaches. We're known for our expertise in hernia repair. We've performed thousands of procedures on the abdomen, intestines, esophagus, stomach, small bowel, colon, liver, pancreas, gallbladder, bile ducts, thyroid and parathyroid glands, skin and breasts. We are experts in the surgical treatment of all types of cancer, including colon cancer, breast cancer, thyroid cancer, stomach cancer, gallbladder cancer, pancreatic cancer, liver cancer and lung cancer. When cancer is diagnosed and a surgical procedure is done, we make sure patients are scheduled with the appropriate specialists, including medical oncologists and radiation oncologists. Because healing and recovery are typically faster and easier with a minimally invasive approach, our philosophy is always to use the least invasive approach possible that brings the best possible likelihood of a great outcome. We complete 98% of our surgeries laparoscopically, so patients experience less pain, less blood loss and a shorter hospital stay. Our surgeons pursue ongoing education to ensure they remain up to date on the latest techniques and technology.
