Patient Care Philosophy

As a pathologist, I incorporate all the information, quality resources and team approach necessary in order to achieve the most accurate diagnosis possible for patients so that they can receive the optimal treatment they deserve. For example, I will take the time to discuss with patient's primary clinicians about symptoms or incorporate the latest published research to best specify a diagnosis.
