Testimonial:

I’ve known I wanted to be a pediatric hospitalist since my days in medical school, particularly inspired by the great clinical educators I’ve had throughout my training. After graduating from a high-volume and high-acuity pediatric residency, I felt well-trained to take care of patients, but decided to pursue a fellowship in hospital medicine to further my skills in teaching. Little did I realize how much more there was to learn in this exciting and growing field! The first year of the fellowship provided me exposure to such a diverse range of clinical, educational, administrative and research encounters; the second allowed me the time and mentorship to develop my specific interests and projects. I discovered in this process a passion for work in quality improvement and patient safety that I had never known, and in the meantime have been able to integrate teaching a quality curriculum for the residents, as well as participate in a national collaborative designed to improve communication between providers at the time of hospital discharge. I am incredibly honored to have been the first fellow for a wonderful group of hospitalists at Children's Hospital Los Angeles and grateful for the dedicated time to complement my clinical work with the pursuit and development of my academic and administrative interests.

Testimonial:

My journey to become a pediatric hospital medicine fellow at CHLA did not start right out of residency, but rather after I had already embarked on a career as a pediatric hospitalist at a community hospital. While my work as a community pediatric hospitalist was rewarding in many ways it also helped me recognize that there were skills I needed to acquire in order to go from being merely a good pediatric hospitalist to an exceptional one. I joined the fellowship program at Children’s Hospital Los Angeles with the goal of enhancing my clinical, teaching, quality improvement, and research skills, and thus far this program has delivered on all of these fronts. In particular, I am enjoying the opportunity to learn more about research methodology, and the guidance from my excellent and enthusiastic research mentor. Informed by my experience as a community hospitalist I am pursuing a research project comparing the care of children with technology dependence in children’s versus non-children’s hospitals.
