“As an athlete in high school and college, I spent a lot of time around sports medicine physicians.  I was greatly impressed with how they helped me and other athletes get back into the game.  Since I’ve always loved the challenge of making people better, the decision to enter orthopedics was pretty much a foregone conclusion.  Today, I’m still very active with athletics, both as a participant and vicariously, through my patients.”

K. C. Chang, MD

“I would like to take a moment to tell you why I chose medicine as a career.  My father is a physician, so I was naturally intrigued with the possibility of making medicine my career.  When I asked my father for advice, he strongly suggested that I consider specializing in something I was both very good at and that I enjoyed doing.  I really enjoy physiatry, so I guess I’m following dad’s advice.”

“As a kid, I was fascinated by medicine.  A family friend was an OR nurse and suggested I volunteer at my local hospital.  I thought I wanted to become an emergency room doctor, but in medical school I found that I really enjoyed orthopedics and surgery the most.  I like helping fix people from the start of their treatment to their final recovery.”

“The spine is an exciting and complex part of the body which has always been an area of interest for me.  The importance of a healthy, well functioning spine is the ‘backbone’ to a healthy well functioning life. It is remarkable how durable and strong the spine is as it holds people erect while protecting the most delicate structure in the body; the spinal cord. I enjoy the anatomy of the spine and the important role it plays in the body.’

Peter A. Looby, MD

“It seems like a career in medicine has always been my destiny. My grandfather and great grandfather were small town physicians in South Dakota and my dad was a practicing OB/GYN in Sioux Falls. As a youth, I suffered three broken arms from various injuries and then blew out two knees playing football that required surgery. So, I guess my interest in orthopedics was inspired by first-hand experience.”

Matthew J. McKenzie, MD

“I would like to take a moment to tell you why I chose orthopedics as my career. I grew up in a small town in central South Dakota where my father was a veterinarian and although I grew up and admired the work he did, I was not sure I wanted to follow in his footsteps. At the age of 16, I had a significant injury to my right knee. I became intrigued with the way an orthopedic surgeon took me from being nearly incapacitated and unable to get around and training me back to health where I was able to resume normal activities in a relatively short period of time. I eventually decided to enter medical school and progress through my orthopedic training with a goal of providing the same type of treatment to my patients.”
