About Me
Dr. Montgomery is a clinical psychologist whose research, training, and clinical efforts are focused on improving patients’ quality of life associated with cancer and its treatment. In particular he is focused on developing and testing mind-body interventions to reduce the symptoms and side-effects associated with cancer and its treatment, such as including pain, nausea, and fatigue. His work recognizes that how we think (e.g., how we evaluate situations, our expectations about how we’ll react to medical treatment), and how we feel emotionally (e.g., anxiety, distress) can have profound effects on how we feel physically. His goal is to provide all cancer patients with the tools and skills they need to enhance their quality of life during the rigors of cancer treatment.
Dr. Montgomery holds two titles at ISMMS – Professor and Vice Chair in the Department of Population Health Science and Policy, and Director of the Center for Behavioral Oncology. Dr. Montgomery also has a secondary appointment in the Department of Psychiatry and is the Director of Psychological Services at Mount Sinai’s Dubin Breast Center. He is a past president of the American Psychological Association’s Society for Psychological Hypnosis (Division 30), and a Fellow of the American Psychological Association. He received his Ph.D. in clinical psychology from the University of Connecticut in 1995, completed a fellowship in Psycho-oncology at Memorial Sloan-Kettering Cancer Center in 1997, and received post-doctoral training in health economics at Columbia University. He has published more than 100 peer-reviewed empirical articles, and has received funding from the National Cancer Institute, the National Center for Complementary and Integrative Health, and the American Cancer Society for his research and training efforts.
Dr. Montgomery is dedicated to mentoring and cancer education, as evidenced by his role as a Principal Investigator of NCI R25E and T32 awards, his direct mentoring of pre- and post-doctoral fellows in behavioral oncology, his supervision of psychology externs, and his teaching in in Mount Sinai’s Graduate School.
Dr. Montgomery’s research work has been recognized not only in scholarly contexts (e.g., conferences, journals), but also in the national and international media. His work has been discussed in multiple media outlets, including: New York Times, Wall Street Journal, Good Morning America, ABC News, CBS News, and NPR.

Research
Dr. Montgomery’s research focuses on developing, testing and disseminating psychological and integrative interventions to reduce suffering related to cancer and its treatment. Critical findings are: 1) Through an RCT of breast conserving surgery patients, he and his group found that patients who received a brief presurgery hypnosis intervention needed less propofol and lidocaine during surgery; reported less pain intensity, pain unpleasantness, nausea, fatigue, discomfort, and emotional upset after surgery; and, cost the institution $772.71 less per patient than patients randomized to an attention control (empathic listening) group. 2) In an RCT of breast cancer radiotherapy patients, our group found that that a brief intervention including cognitive-behavioral therapy plus hypnosis (CBTH) reduced fatigue in patients during radiotherapy, and for up to six months following radiotherapy. Results support CBTH as a highly effective means for controlling and potentially preventing fatigue in breast cancer radiotherapy patients. 3) Dr. Montgomery is presently working to disseiminate this CBTH intervention by training psychosocial cancer care providers across the country in the intervention. This work is supported by the NCI R25E mechanism. 4) Throughout his program of research, Dr. Montgomery has demonstrated that response expectancies and emotional distress play important roles in the development of cancer patients’ treatment-related side effects (e.g., chemotherapy-related nausea, postsurgical quality of life). Current research efforts include a randomized controlled trial to study the use of a three-session hypnosis intervention (R01AT008762, NCT02657993) to reduce musculoskeletal pain and to improve medication adherence in breast cancer survivors prescribed aromatase inhibitors. Overall, Dr. Montgomery’s program of research focuses on developing, testing, and disseminating the effects of behavioral medicine and integrative interventions on the lives of cancer patients and survivors. Through this work he hopes to improve the quality of life of individuals affected by cancer and its treatment.
