Get to Know Me
I am a board-certified medical oncologist who specializes in treating patients with gastrointestinal cancers. I have a special interest in caring for patients with an inherited risk for colorectal cancer.
I work very closely with a team of surgeons, oncologists, gastroenterologists, and radiation therapists to provide the best treatment and care for each patient.
In addition, I have a separate genetics clinic where I provide clinical counseling and genetic testing for people who may have an inherited predisposition to gastrointestinal or other cancers. Based on genetic test results and family history, I help men and women with cancer incorporate genetic information into their treatment plan and the surveillance of cancer after treatment.

My research focuses on the discovery of novel cancer-susceptibility genes and the development of new approaches to cancer screening and prevention in high-risk families. I have received an American Society of Clinical Oncology Career Development Award, and more recently was honored to be selected for a Clinical Investigator Award by the Damon Runyon Cancer Research Foundation for my research on the genetic causes of cancer in patients with early-onset disease.
Through funding secured via the National Institutes of Health, I am also studying genetic susceptibility in patients who have more then one malignancy. I am an active member of the American Society of Clinical Oncology and recently served as chair of its education committee on cancer genetics.
A gastrointestinal (GAS-troh-in-TES-tih-nul) medical oncologist is a cancer doctor who specializes in gastrointestinal (GI) cancers. This includes anal, colorectal, esophageal, gastric (stomach), liver, and pancreatic cancers, as well as GI stromal tumors and neuroendocrine tumors.
A clinical geneticist is a scientist with special training in diagnosing and treating genetic conditions. They can help explain your risk of getting a genetic condition that is passed on from parents to children.

Excellent
I didn't know I had an appt. I don't feel it was communicated enough to me about the appt. It went up on my chart. However the doctor called me and was excellent.
She was very knowledgeable and professional explaining everything in detail.
The genetics team is amazing. Truly amazing. It's been a long journey of almost 20 years but the teams constant follow up, check ins and updates when new science became available led to a diagnosis after almost 20 years. The best part of this news is my daughter can now be tested for the mutation rather than undergoing surveillance for the rest of her life! The team seemed as excited as I was to share the news.
I feel very fortunate to be in such great care
