About Dr. Sethness
Dr. Sethness


As an internal medicine and pediatric doctor, I enjoy caring for patients of all ages and getting to know families. I particularly love being a primary care physician because I can develop relationships with patients over time. By learning about my patients’ lives and communities along with their needs and values, I can partner with them to make the best individualized care plans possible. I am excited to be a part of a fantastic physician group at UCHealth, a system where providing outstanding patient care is the priority.

My husband and I met in medical school in San Francisco, California and continued our training together in Houston, Texas. We moved to Denver so that he could pursue a Neurology fellowship in Epilepsy and decided to stay because we loved everything that Colorado had to offer. We have an amazing young son and delight in watching him grow, learn, and discover new skills. Our home is also filled with a sweet lab mix dog and two playful cats. In our free time, you can find us outdoors hiking, biking, running, camping, or snowboarding. We also like to travel; our hope is to one day visit all of the U.S. National Parks!
