Patient Stories

More About Dr. Merrell

When did you know you were going to be a healthcare provider? (or why did you select a career in healthcare?)
I worked in business for 6 years prior to going to medical school. I realized I wanted more than a job, I wanted something that was intellectually interesting and emotionally rewarding. I also worked on an ambulance in Denver, lights and sirens at 2am is exciting!
What inspires you about your work?
So many things. The great dedicated team I work with inspires me to be a better human and a better surgeon. The patients, some of whom have very serious injuries are inspiring to see how hard they work after surgery to remake huge gains in the function in their arm (I tell them 1/2 the results are from what I do in surgery and 1/2 are what they achieve through their therapy, it takes a team). Thirdly, hand surgery is a relatively young field which started just after World War 2. We continue to make advances in technique and technology and understanding. I am proud to be a part of those efforts.
How would you describe your approach to patient care?
The arm is connected to a patient…We are treating the arm and supporting the patient in that journey! Also we focus on problems and solutions. Sometimes a patient comes in with an MRI finding or a bump and we have to correlate that with their life…is it a problem that needs solving or do we just need to understand more about the condition we have.
