About Me
I have always believed there is no greater purpose than to relieve the discomfort of others. After college, I conducted research for the U.S. Department of Homeland Security on preventing biological terrorism and volunteered at a free medical clinic, where I counseled people about their health. I enjoyed working with patients one-on-one, so I decided to go to medical school. I had been an engineering major in college, and surgery appealed to me because it is both technically and intellectually challenging. I also wanted to help patients when they feel vulnerable and afraid.
Many of my patients experience debilitating symptoms, and I am honored to help them. I treat people who have hemorrhoids, fissures, diverticular disease, and colon, rectal, and anal cancer.
I have advanced training in evaluating and managing pelvic floor disorders, such as pelvic organ prolapse and fecal incontinence. I am also trained in laparoscopic and robotic surgery. These minimally invasive techniques lead to a shorter recovery time and less pain.
I take my role as a health educator seriously. My goals are to empower patients to make informed decisions about their healthcare and to help restore their wellbeing and dignity. I feel satisfied when my patients understand their medical condition and have hope for getting better. I am committed to improving patient care through technology and research.
