As a pathologist, you may never meet me in person, but I am working hard behind the scenes to provide you with the same high quality and thoughtful care that I would my own family. My job is analyze the tissue from your biopsy or surgical procedure under the microscope and make an accurate diagnosis, which guides your other doctors to offer you the most effective care. I treat every case as more than a number, piece of tissue, or slide - you, the patent, are always on the front of my mind.
