About Me:

I am Board certified in General Surgery and a Fellowship trained Foregut surgeon. After obtaining my medical degree from Creighton University, I completed my General Surgery residency at Oregon Health and Science University and went on to complete a fellowship in Thoracic and Foregut surgery at Swedish Medical Center. I chose a specialty in Foregut Surgery as it allows me to deal with complex problems with access to multiple different techniques to find the best solution for each patient. My aim is to provide comprehensive care, including both diagnostics and treatment through minimally invasive and endoscopic techniques. I enjoy the opportunity to treat both malignant and benign esophageal and gastric conditions as well as general surgery problems including hernia, gallbladder and intestinal diseases. Outside of work, I enjoy spending time with my wife and 2 children, enjoying the outdoors and exploring the Pacific Northwest.
