Dr. Berry joined the Division of Thoracic Surgery at Stanford in August 2014. He came to Stanford from Duke University, where he had most recently served as Associate Professor. He received his medical degree at the University of Pennsylvania School of Medicine after receiving bachelors and masters degrees in Electrical Engineering at the University of Pennsylvania. He completed his residency in Cardiothoracic Surgery at Duke University Medical Center after performing a residency in General Surgery at the Hospital of the University of Pennsylvania. His Cardiothoracic Surgical training included a year dedicated to Minimally Invasive General Thoracic Surgery, a period that also included an American Association for Thoracic Surgery sponsored Traveling Fellowship at the University of Pittsburgh.

Dr. Berry practices all aspects of thoracic surgery, including procedures for benign and malignant conditions of the lung, esophagus, and mediastinum. He has a particular interest in minimally invasive techniques, and has extensive experience in treating thoracic surgical conditions using video-assisted thoracoscopic surgical (VATS), laparoscopic, robotic, endoscopic, and bronchoscopic approaches. He serves as the co-Director of the Stanford Minimally Invasive Thoracic Surgery Center (SMITS), and has both directed and taught in several minimally invasive thoracic surgery courses.

Dr. Berry also has a Masters of Health Sciences in Clinical Research from Duke University. His clinical research activities mirror his clinical interests and activities in optimizing short-term and long-term outcomes of patients with thoracic surgical conditions. He has more than sixty peer-reviewed publications, most of which are related to both the use of minimally invasive thoracic surgical techniques as well as evaluating outcomes after treatment of thoracic malignancies. His clinical practice and his research both focus on choosing the most appropriate treatment and approach for patients based on the individual characteristics of the patient and their disease process.

Dr. Berry is an INCREDIBLE physician; I would recommend him with no reservations to anyone who suffered from a thoracic tumor; no one could have removed my tumor with more skill. than Dr. Berry.
