Raymon Grogan, MD

Assistant Professor of Surgery

Director, Endocrine Surgery Research Program

Co-Director, Von Hippel-Lindau Disease Clinical Care Center

As an expert in endocrine surgery, Raymon Grogan, MD, specializes in the management of endocrine gland disease, including thyroid surgery and parathyroid surgery. Dr. Grogan treats patients with endocrine cancers, such as thyroid tumors and adrenal tumors, as well as benign gland disorders.

As a clinician and a scientist, Dr. Grogan is actively involved in clinical, translational, epidemiological, and basic science research. He is currently working on identifying genetic and proteomic biomarkers in thyroid and adrenal tumors. Understanding the genetic and molecular changes in these tumors could lead to better diagnosis and treatment strategies for patients with cancer. Dr. Grogan and his research group also are studying the unexplained rise in thyroid cancer incidence worldwide. Understanding the cause of this rise can lead to improved prevention, diagnosis and treatment of thyroid cancer. The ultimate goal of Dr. Grogan's work is to improve patients' lives by translating state-of-the-art research findings into everyday clinical practice.

Learn More About Dr. Grogan

Dr. Grogan and his surgical team’s innovative transoral thyroidectomy procedure offered Sherri Caine a truly scarless alternative to thyroid gland removal. Watch her story.

Dr. Grogan is part of a surgical team that was the first in the Midwest to remove diseased thyroid and parathyroid glands using a minimally invasive approach that leaves no visible scar.

For nearly a decade, surgeons have been searching for a more cosmetically appealing way to remove a diseased thyroid gland. Dr. Grogan explains a new procedure that makes a scarless thyroidectomy possible.

Dr. Grogan removed two life-threatening neuroendocrine tumors from a patient with the rare genetic disorder, von Hippel-Lindau (VHL) disease. Grogan co-directs the multidisciplinary VHL Clinical Care Center at the University of Chicago Medicine.

Dr. Grogan was recently appointed as a Junior Faculty Scholar of the Bucksbaum Institute for Clinical Excellence.
