I’m from Big Spring, Texas. I played volleyball at ASU before going to medical school at Kansas City University Medical School in Joplin, MO.
I had never heard of Internal Medicine before my third-year rotations, but then fell in love, switched specialties that month, and I now plan to be a hospitalist.
I had only been to Denver a couple of times before coming here recently, and now I absolutely love it and hope to stay here. I moved here with my boyfriend Casey and our two dogs, Arlo and Pippy. We are looking forward to skiing, hiking, playing video games at home and enjoying all the types of the local sports that Denver offers. We are especially excited about football, as everyone in my family is a huge Broncos fan. I’m hoping that my two sisters and parents will visit frequently!
I was born and raised in Boise, Idaho. From a young age, I was fascinated by innovation and the human experience. Early in life, I assumed a caregiving role for multiple family members, inspiring my pursuit of medicine. During my undergraduate years at the University of Idaho in Moscow, I co-created a viral TED talk titled “A Crash Course in Organic Chemistry” with my mentor, Dr. Jakob Magolan, and worked in a multidisciplinary video game studio with my computer science and genetics professors.
After graduating with degrees in microbiology, molecular biology, and biotechnology, I went on to the University of Colorado School of Medicine where I served as executive producer on an upcoming documentary, “Diversity and Inclusion in Medicine: The Journey.” I’m passionate about nearly every discipline within and outside of medicine, and am eager to begin this residency as an internist at Sky Ridge Hospital.
In addition to mastering the skills to become an excellent physician, I am committed to finding creative ways to bring comfort and joy to his patients during their most challenging times.
