Katie Ganser, PA-C

Prior to graduating from PA school from the University of Colorado, I earned my bachelor’s in Biology from Merrimack College in Massachusetts and Master’s in Business and Management from Trinity College in Dublin, Ireland. While living in Dublin, I was a Victory Scholar through Sport Changes Life and coached at risk youth, played basketball, and traveled much of Europe!

I grew up in Needham, MA with my two incredible younger sisters and two very inspiring parents and moved in Colorado in 2018 with my partner and our two dogs. When not at the hospital, you can find me playing in the mountains, fostering puppies, and painting!

I spent many of my formative years working with children as a basketball coach, camp counselor, aide for medically complex children, and a volunteer at children’s hospitals’. Though I started PA school with an open mind about what population I would want to work with, as soon as I had my first pediatrics rotation it was clear that working at Children’s Hospital of Colorado would provide the opportunity to combine my passion for medicine with the unique resiliency of children and their families. How many people get to say they work at a place where they can watch service dogs wrestle in the dog park, play Spiderman with kids walking down the hall on rounds, and help a young aspiring medical provider listen to their own heart for the first time all? We get to do this – every day – while serving the complex physical and emotional needs of our patients.

I am honored to be part of this fellowship program to further build my foundation in pediatric inpatient medicine. It is a privilege to help provide care to a diverse array of children and their families and learn from leading medical experts.

Chelsea Hartman, CPNP-AC

Hartman, Chelsea

In 2019, I graduated with my Doctorate in Nursing Practice, certifying in both Pediatric Acute Care and Pediatric Primary Care from Creighton University. Prior to graduate school, I was a Division I swimmer at The University of Nebraska in Omaha while pursuing a Bachelor’s in Community Health Education and then went on for my Bachelor’s of Nursing at Creighton University. I have spent almost all my nursing career as an Acute Care Float Nurse at both Children’s Hospital and Medical Center in Omaha, Nebraska and here at Children’s Hospital Colorado.

Originally from Colorado, it has been so important for me to stay close to my family while working somewhere that I have always wanted to work, which makes me thrilled to be chosen as a Fellow in this program! I am so excited for the educational opportunities which will help me to become a more well-rounded provider while supporting me as I make the transition from bedside nurse to provider in the only field that I have ever loved, pediatrics. 

Davis Lehman, PA-C


I was born and raised in the San Francisco Bay Area and studied at University of California, Santa Cruz where I earned a bachelor's in Ecology and Evolutionary Biology. I went on to complete my physician assistant training at Pacific University in Hillsboro, Oregon. I am incredibly grateful to be a part of the Inpatient APP Fellowship program.

As a youth lacrosse coach I have always been drawn to working with children and their families. My passion for pediatric acute care medicine took flight while working as a technician in a pediatric ICU. This program stood out to me because it offers such a unique and diverse array of speciality experience that cannot be found elsewhere. It is an exceptional opportunity for any APP interested in learning the subtleties of pediatric critical care medicine or looking to develop the confidence, competence, and flexibility it takes to bring their very best to their peers, the patients, and the parents.

Morgan McMahon, PA-C

I grew up in NC with my amazing parents and triplet younger siblings who sparked my interest in health from a young age. At Wake Forest University, I created an interdisciplinary major in Global Health, and then worked with an inspirational group of providers at a primary care health start-up. I next attended Stanford University’s MSPA program with a concentration in Healthcare Leadership and Administration where I also helped develop a healthcare tech nonprofit focused on health coaching.

I am honored to have the opportunity to be a part of this fellowship program to fuel my growth as a provider and a leader. I look forward to applying my passions for motivational interviewing, healthcare tech, and DE&I in healthcare while learning from the exceptional providers I am surrounded by each day at Children’s Hospital of Colorado. And, on my days off, I’m thrilled to continue exploring outdoor adventures in Colorado with my husband and dog.
