About

Bio

I spend the majority of my time dealing with complex diagnostic oncology issues, primarily from the surgical pathology side. At the University of Oklahoma, I've managed the GI tumor board pathology section for the past seven years, and dealt with an abundance of pancreatic, esophageal, gastric, liver and colon cancers. I also have an interest in soft tissue and bone tumors.

Specialties
Doctors may have more than one area of specialty interest. Board certification in a specialty area means the doctor has completed formal training and has practice experience in that specialty, and has passed the certification examination from the corresponding accredited medical specialty board.
