I have worked as a nurse practitioner in the GI department at Nationwide Children's Hospital for 17 years.  While I have had a variety of roles within the division, my primary focus for the past 10 years has been caring for patients with Inflammatory Bowel Disease in both the inpatient and outpatient setting.  We have a large practice with 23 Gastroenterologists, 9 fellows, and 6 APN’s which has allowed me the ability to specialize in this one area.  I became a member of APGNN over a decade ago and remain a member because this is the only nursing organization in the country that allows me to network and learn from other Pediatric GI nurses.  This has substantially improved my clinical skills and knowledge with regards to the care of the pediatric GI population.  One thing you may not know about me… I have 3 kids that are very involved in volleyball, so between club, school, and college games I feel I am never too far away from a volleyball court!   And, while it may be super loud, it is never cold like those crazy early spring soccer games – so glad they changed to indoor sports!

I have worked as a nurse practitioner in the GI department at Levine Children's Hospital for 9 years.  Prior to my role as a nurse practitioner, I worked as a staff nurse in the Pediatric ICU and Pediatric Emergency room settings since the late 90s. Although I care for patients with a plethora of gastroenterological conditions, my two specialties are in regard to enteral feeding tubes and caring for patients with Inflammatory Bowel Disease primarily in an outpatient setting.  We have a medium sized practice with 8 GI attending physicians, and 3 ACPs. I became a member of APGNN in 2008 as soon as I joined the practice at the encouragement of my primary supervising physician.  I have grown and prospered in my role in Peds GI directly related to the networking and professional development opportunities afforded by the organization. Learning directly from other experts in this field at our annual conference and through my board and committee work, has kept my skills relevant and dynamic.  My experience in leadership through the APGNN executive office has been challenging but has enriched my personal and professional life in more ways than I can count.

I’m honored and excited to be the next APGNN President Elect.  My background is solely in Pediatric Nursing since graduating from UNLV in 1996, then getting my PNP from SUNY Stonybrook in 2002, and going straight into Peds GI from there.  I have now been working in Peds GI private practice for 15yrs doing a little bit of everything.  I joined APGNN in 2003 and enjoyed my time with Membership since 2005.   As much as I love caring for “little butts and guts,” my favorite job is being a mom to my 13yr old daughter.

After graduation from nursing school I spent 2 years working in an adult intensive care unit and decided I would prefer more patient interaction and a pediatric focus.  I was hired in the field of Pediatric Gastroenterology at the University of Nebraska under Dr. Jon Vanderhoof where I was able to be involved with complex case management of children with a variety of gastrointestinal (GI) disorders including short bowel syndrome, those undergoing intestinal transplant and Crohn’s disease functioning as the Clinical Research Coordinator.  I currently work as a nurse practitioner in Pediatric Gastroenterology with Dr. Vanderhoof where I spend 80% of my time with clinical responsibilities and 20% time functioning as a research coordinator within the GI department at Boys Town National Research Hospital. I see patients 3 times a week in a clinic setting at our outreach locations in 3 cities outside of Omaha.  I have been an APGNN member since 1985; one year after the group was formalized and I have held various offices. The organization has grown and I find it provides valuable information and networking opportunities which have advanced my practice.    Second only to my husband and children, my position provides me immense personal fulfillment.

I am a Certified Pediatric Nurse Practitioner at Boston Children's Hospital within the Motility and Functional Gastrointestinal Disorders Center and the Aerodigestive Center, and am the Clinical Coordinator for the Multidisciplinary Functional Abdominal Pain Program.  I care for patients with complex motility disorders, aerodigestive disorders, and patients with pain-predominant functional GI disorders.  Prior to my work at Boston Children’s Hospital, I was a registered nurse on the Pediatric & Small Bowel Transplant Unit at Georgetown University Hospital, followed by a nurse practitioner in Pediatric Gastroenterology with an emphasis on the Inflammatory Bowel Disease population. I have been a member of APGNN since 2012 and contributed to the Social Media and Program Planning committees in past years. I also had the privilege of presenting with Dr. Samuel on  multidisciplinary approach to Functional Abdominal Pain Syndrome at the World Congress in 2016.  I enjoy program development and believe that patient and family education is not only a critical aspect to quality care, but a fundamental building block of nursing.
