I love interacting with patients and getting to know them. Helping them navigate the health care system and ensuring they get the care they need is extremely gratifying.

To properly care for patients, I believe a team approach is important, as well as multiple facets that must be considered beyond just their health care to also include their family, life experiences, and spirituality.My role is to help them make the best choices for their overall health.

In medicine, a major goal is to decrease pain and discomfort and increase patients' quality of life, and the GI specialty is no exception. This means I get to first work with patients to determine the daily life activities that are meaningful to them. I then take those goals and using my knowledge and training, work to find lifestyle, medication, or surgical interventions to help them get back to whatever it is they want to be doing again.

One of the greatest rewards is hearing a patient say that because of whatever intervention we implemented they are now able to do those things again - whether it's going out to eat with friends, playing with their kids, getting back outdoors, or simply enjoying their life.
