Dr. Janet S. Rader is currently the Jack A. and Elaine D. Klieger Professor and Chair of the Department of Obstetrics and Gynecology. She received her medical degree from the University of Missouri in Columbia, Missouri and completed her residency in Obstetrics and Gynecology at Michael Reese Hospital and Medical Center in Chicago, Illinois. She then served as a Research Fellow in the Department of Molecular Genetics and Cell Biology, Howard Hughes Medical Institute at the University of Chicago. Dr. Rader completed a fellowship in Gynecologic Oncology at Johns Hopkins University, Baltimore, Maryland.

Dr. Rader has been a continuous recipient of NIH and ACS funding since 1994. Her research work is in early molecular changes in cervical cancer and genetic predisposition. She is on the steering committee of The Cancer Genome Atlas (TCGA) for ovarian cancer and the NCI Cervical Cancer Task Force. She is a member of the Cancer Prevention and Control Committee and the Committee on Experimental Medicine of the Gynecologic Oncology Group. Dr. Rader is associate editor for Cancer Epidemiology, Biomarkers & Prevention and has authored or co-authored 139 peer-reviewed articles. She is PI for several clinical trials in gynecologic malignancies. She is a member of many organizations, including: The Society of Gynecologic Oncologists, The American Society of Clinical Oncology, The American Association for Cancer Research, and The American Society of Human Genetics.

Her laboratory focuses on advancing cervical cancer prevention and control. Infection with high-risk human papillomavirus (HPV) is the primary inciting event, but it is evident that additional factors must be involved, since only a small proportion of infected women develop cancer. The laboratory concentrates on identifying genes involved in the progression of cervical cancer through the analysis of molecular changes in preinvasive and invasive neoplasias of the cervix, in addition to identifying host genetic susceptibility polymorphisms in the progression of disease.

I know I can depend on them for whatever I need or am concerned about.
Dr. Rader is excellent in every aspect. I drive from Oconto to Milwaukee to be under her care because she is the best!
The NP was very attentative when discussing my neuropathy. Gave me options to choose. She is very pleasant to talk to and makes me feel at ease during the exam. Thumbs up.
Dr Rader was fantastic in answering my questions and explaining my care and concerns. She went beyond standard to customize for me.
Everyone I have had contact with are awesome people. I couldn't be happier with Dr. Rader and the staff.
The entire experience was amazing. Dr Rader was fabulous.

I have been coming here for over a year for chemo etc. I have never had a bad experience and "everyone" has been awesome. I believe I have the best doctor for my cancer and her staff Is very good also. I have told family and friends that Froedtert Hospital Is the place to go. Great Job.
Dr. Rader went way above and beyond to provide services for me and to make me feel secure in our decisions that we made. Her team is wonderful. It was just a very great experience. Dr. Rader is such a capable, compassionate physician. I was truly amazed.
I was extremely glad that they got me in to see a doctor so quickly. I am sorry the first person that I worked with was having a bad day or a sad day or a mad day. I don't know, but everyone else I worked with was so kind and so wonderful and I would easily recommend anyone going to this clinic the courage clinic, I'm very grateful that Dr. radar is the doctor that I was assigned to and the young ladies that she was working with were incredibly kind and they were kind of funny when they were checking inside my body. They were kind of cute you're gonna feel safe or nice, so I'm I'm just very grateful and I'm very grateful that I was put on a waiting list just in case his surgery date opens up faster and I'm very grateful that they got me signed for surgery in four weeks. It seems like a terribly long four weeks inside my head but when I look at a calendar, I know it's not really that long . I just really want it out of my body. I am very grateful for the team that I'm working with just incredibly grateful so that's all.
Dr. Rader & her team are amazing. I'm thrilled with their excellent care for me over the past 5 years. I would recommend the entire team to anyone needing quality care. Grateful for all of them.
