Pediatric Gastroenterology

Welcome to the Pediatric Gastroenterology Fellowship Program

The Division of Pediatric Gastroenterology, Hepatology and Nutrition at the Medical College of Wisconsin is committed to the training of our fellows as academic pediatric gastroenterologists. The purpose of this fellowship is to train academic pediatric gastroenterologists who can function both as clinicians and scientists. The Fellowship Program will be under the direct supervision of Dr. José Cabrera, Assistant Professor of Pediatrics. In addition, once a research mentor has been identified, that individual will serve as the faculty advisor for the research portion of the program. Each fellow will also develop a scholarship oversight committee to oversee his/her progress through the program. 

The Medical College of Wisconsin is associated with Children's Wisconsin, a free-standing 306 bed children's hospital located in Milwaukee, Wisconsin. Children's Wisconsin ranks as one of the top Children's Hospitals in the United States. The department of Pediatrics currently has 240 full time faculty members. Other facilities on the Milwaukee Regional Medical Complex campus include the Medical College of Wisconsin and Froedtert Hospital.

The Division of Pediatric Gastroenterology, Hepatology and Nutrition has 16 pediatric Gastroenterologists, 5 Nurse Practitioners, 11 Dieticians, 1 clinical psychologist, and 1 independent lab research PhD. Clinical activities include general pediatric gastroenterology and specialized clinical programs in Feeding and Swallowing Disorders, Obesity (NEW Kids Program), Inflammatory Bowel Disease, Cyclic Vomiting Syndrome, Motility Disorders, Liver Transplant, Celiac Disease, Eosinophilic GI Disorders, Nutrition, Functional GI Disorders, Constipation and Infant Gastroesophageal Reflux. Research programs include Inflammatory Bowel Disease, Genetics and Pharmacogenetics, Mucosal Immunology, Visceral Pain and Developmental Biology. Our large faculty with a large breadth and depth of clinical and research expertise facilitate clinical learning from different styles and a variety of research pursuits.

About the Program
During the first year, the Fellow will be exposed to a wide variety of patients with gastrointestinal, hepatic and nutritional diseases. Education will focus on the development of expertise for appropriate work-up, diagnosis and treatment of these conditions. In addition, the Fellow will develop familiarity of the pediatric and adult gastrointestinal literature through literature search and active participation in patient care conferences, departmental conferences and journal clubs. Towards the end of the first year, the Fellow will identify a research mentor and together select a specific project to pursue during the second and third year of the Fellowship under the direction of the mentor. During the second and third years, the Fellow will learn research techniques, develop project for presentation at a national meeting and develop experience in writing a grant proposal. 

We will accept two fellows through the National Resident Matching Program (NRMP).

Fellows Through the Years

Vikram Christian, MD – Graduated June 2019 and became Pediatric GI Faculty at University of Minnesota. “As a pediatric resident, I had aspired to complete my fellowship training in an academically strong program that offered good clinical experience. I found the Pediatric Gastroenterology training program at the Medical College of Wisconsin to be exactly that. Strengths of the program include a large faculty group with diverse clinical interests, high patient volume and complexity, abundant procedural experience, several well-established clinical programs, extremely supportive clinical and administrative staff and a strong focus on research/academics. Constant mentoring and support over the past three years have allowed me to conduct clinical research, present at national conferences, publish in reputed journals and solidify a career path in nutrition. The faculty, administrators, nurses, dietitians, psychologists and support staff were very easy to get along with and will be missed as I graduate from training.”

Prasanna Kapavarapu, MD – Graduated June 2019 and became Pediatric GI Faculty at Children’s Hospital of Philadelphia. “The pediatric gastroenterology fellowship program at the Children's Wisconsin/Medical College of Wisconsin is one of the few outstanding clinical and research fellowship programs in the nation which offers unequivocal opportunities for fellows in training. My fellowship journey here at Children's Wisconsin/MCW has taught me a lot of important life worthy lessons. The breadth of clinical care exposure during fellowship is worth mentioning especially given that Children's serves as the tertiary referral center for the whole state of Wisconsin. The GI Division's commitment to encourage research by fellows is enormous, and this is reflected very well through the support I received in pursuing both bench and clinical research during my fellowship. The Neurogastroenterology and Motility team is a big strength of this program, and I was fortunate to be trained by this excellent team to build a career as I graduate from here to join a premier institute at the Children's Hospital of Philadelphia. Above all, I really cherish my time and the relations built during my fellowship here at Children's Wisconsin/MCW. “

Sarah Cole, MD
- Graduated June 2018 and became Pediatric GI Faculty at South Dakota – Avera McKenna Hospital and University Health Center. “After interviewing for fellowship here in Milwaukee, I knew that this program was the perfect fit for me. My initial impression proved to be true as my fellowship experience was challenging and extremely educational. The faculty are each specialized in various areas within pediatric gastroenterology including advanced endoscopy, eosinophilic esophagitis, inflammatory bowel disease, cyclic vomiting syndrome, hepatology, nutrition, and motility. Fellow are provided with a substantial amount of support in pursuing their research interests. I was involved in the care of patients with a wide variety of interesting presentations and disease processes. The faculty are very helpful and provide an appropriate amount of autonomy. I feel very prepared to begin my career as a pediatric gastroenterologist.”

Ammar Khayat, MD - Graduated February 2018 and returned to Saudi Arabia to practice. “I’m very proud to have been trained in this program as it offered me the opportunity to not only work with world experts in the field but to be exposed to all Sub-specialties of Pediatric GI such as liver diseases, IBD, functional, nutrition and TPN care, CVS, obesity, and motility where this program exiles. The program also allowed me to customize my training based on my needs and my future job and interests. This was - in my case more so than others- a big plus considering the work environment I’d be in is completely different. A big strength I’d like to highlight is my comfort level in endoscopy procedures including specialized procedures like esophageal dilations and PEG tube placements; thanks to the high volume of procedures performed in this program. Academically, I had the opportunity to work on different research projects of my choice and based on my interests. My mentors were very supportive and involved in guiding me through every step. Most faculty in this program were very encouraging and idea-stimulating so I had no shortage of opportunities to work on projects. As an international graduate, again I’m very proud to have graduated from this program that gave me the confidence to practice Pediatric GI in any kind of clinical or academic setting.” 

Julia Fritz, MD - Graduate June 2017 and became a faculty member of Pediatric GI at Maine Medical Partners in Portland, ME. “Coming to Milwaukee for my pediatric gastroenterology fellowship was the best decision I ever made. Yes, a large part of that is because I met my future husband in Milwaukee, but it also has to do with the training I got at Medical College of Wisconsin/Children’s Wisconsin. The robust clinical experience (made possible by the size of the hospital and the variety of interests of the faculty) meant that I feel prepared to practice in a smaller, more generalized practice because I was able to care for and learn from a wide range of patients during training. In addition, the flexibility of the program allowed me to pursue my interest in quality improvement and receive the necessary training to make this a part of my future career. While traditional clinical or bench research was not my cup of tea, I feel confident that the program provides strong opportunities and support for fellows seeking this path. More than anything, what makes me thankful for my time at MCW is the people I met there. Nurses, administrators, and faculty members became friends who supported me through the tough times and celebrated my joys (in and out of work). Having a supportive network is essential during fellowship regardless of where you train, and I found it at Children’s Wisconsin.”

Rachel Dunn, MD - Graduated June 2017 and became faculty member of Pediatric GI at St. Vincent Medical Group in Indianapolis, IN. “Choosing a fellowship program is never easy. There are so many things to consider! I first heard about the program at Milwaukee back when I was applying for pediatric residency. Since I knew then that I had an interest GI and heard so many great things about the program here, I decided to pursue my residency and hopefully my fellowship at MKE. Life worked as planned and I am very happy to have completed my fellowship with this program. The size of the program and number of faculty provided both a great general and sub-specialty exposure within GI. I feel that I was exposed to so many rare cases here that I would not have seen at a smaller practice. In addition, I was able to receive training in advanced endoscopy techniques as a fellow! Thanks to my program, I feel ready to pursue my career as a pediatric gastroenterologist.”

Catherine Larson-Nath, MD - Graduated in July 2015 and became a faculty member of Pediatric GI at the University of Minnesota Masonic Children's Hospital. "I had an amazing experience training in Milwaukee. I was supported through every step of the fellowship process from clinical care to research mentorship. At the Medical College of Wisconsin you are exposed to all areas of Pediatric Gastroenterology, from general GI and IBD to more specialized areas of motility, nutrition, feeding team, and liver transplant. This is very unique and makes Milwaukee special and an excellent place for training. Coming into fellowship I was worried about research as I had no experience. Once in Milwaukee I felt well supported and now know that research will always be a part of my career and that is due to my experience in fellowship. Most importantly I feel prepared to start my career as an Pediatric Gastroenterologist and have come away from fellowship with countless new friends and mentors."

Sarika Rohatgi, MD - Graduated in July 2015 and her faculty appointment is pending. "MCW is a great place to get a diverse clinical exposure in a wide variety of basic as well as uncommon GI diseases, outstanding endoscopic procedural experience and good research opportunities. It has a great group with helpful, understanding and approachable colleagues and a strong support system of nurses, nurse practitioners, psychologists and dietitians. Fellowship here has taught me a lot and groomed me well as a physician and a person."
