I am a Level III Certified Pediatric Nurse Practitioner at Boston Children's Hospital within the Motility and Functional Gastrointestinal Disorders Center and am the Clinical Coordinator for the Multidisciplinary Functional Abdominal Pain Program. I care for patients with complex motility disorders, with an interest in pain-predominant Disorders of Gut-Brain Interaction (DGBI). Additionally, I am a member of the GI Safety and Professional Advancement Committees. Prior to my work at Boston Children’s Hospital, I was a Pediatric Liver & Small Bowel Transplant registered nurse at Georgetown University Hospital, followed by a nurse practitioner in Pediatric Gastroenterology focusing on Inflammatory Bowel Disease. I have been a member of APGNN since 2012, serving as the Chair for the Patient & Professional Education Committee from 2017-2019 and President Elect from 2019-2021. My professional joy comes from building relationships with people – families, patients, and colleagues. As APGNN President, my aim is to increase collaboration among members and to promote and advocate for the nursing role in the field of Pediatric Gastroenterology. Outside of work, I love spending time with my husband (Adam) and two little boys (Charlie and Theo). We love animals and have two very old dogs (Everett and Sebastian) and a horse named Melvin.

I have been practicing in outpatient GI for over 12 years. I have worked at Children’s Hospital Colorado in the Digestive Health Institute for 10 of those years and previously worked as an NP in Pediatric Gastroenterology at NYU Langone Medical Center in NYC. As an RN I worked for 5 years on a general pediatric floor at NYU Langone Medical Center. In my current role as an NP, I see general GI patients in our outpatient clinics. I am also very involved in our Intestinal Rehabilitation Program, seeing patients in clinic and on the inpatient service as a consultant.

Within the DHI, I have held the leadership position of Lead Advanced Practice Provider (APP) for the DHI since 2016. In this role I support the APPs in our department with hiring, onboarding, mentoring, scope of practice, and continuing education. I was one of the Tri-Chairs for the Advanced Practice (AP) Council at Children’s Hospital Colorado in which I collaborated with the other chairs to set annual APP goals, represent the voice of APPs in various work locations, determine agenda items, and present at the AP Council Quarterly meetings. I stepped down from this position in early 2021 after 2 years and have remained on the council as one the AP Council Members. In 2019, I attended a 2 day Clinical Leadership Development Program to help improve my leadership knowledge and ability. 

I have been an APGNN member since early 2010. I previously served as the chair for the Clinical Practice Committee for 3 years (2014-2016). This was a wonderful experience that provided both personal and professional fulfillment and I have enjoyed being back on the board as Secretary/Treasurer. Outside of work I enjoy spending time with my husband (Eric) and 2 girls (4 yo and 6 yo). We all enjoy the outdoors, swimming and camping. The girls are learning to ski and I’m sure will be faster and riskier than Eric and me soon!

I have worked as a nurse practitioner in the Department of Gastroenterology, Hepatology and Nutrition at Texas Children's Hospital/ Baylor College of Medicine for the past 11 years.  Prior to that I worked as a Pediatric Nurse in the Pediatric ICU at Texas Children's Hospital for 5 years.  My primary focus has been caring for pre and post liver transplant patients as well as children with fatty liver disease.   We have a large practice with 39 GI/Hepatology attending’s, 9 fellows, 1 advanced transplant hepatology fellow, and 4 APRNs, which has allowed me to specialize in this area.  I have also always been actively involved in our research protocols.  I have been on the Clinical Practice Committee in APGNN for the last 3 years.  During this time, I have networked and helped to develop teaching modules for new nurses/providers while also improving my own knowledge at the same time.  I have 3 children who are actively involved in Cub Scouts, swimming, tennis, and soccer.
