I cannot comment on UIC, but remember that most programs teach fundamentals in growth and development and diagnosis among other areas. The clinical part cannot be mastered in 2-3 years. It takes years of "practice". I still use some of my wire bending skills now, but I have perfected a system of treatment that has been confirmed successful due to the large numbers of patients I have treated. I NEVER learned these techniques in residency.
Learn DIAGNOSIS. This is what separates the specialists from everyone else. The clinical aspect comes later.
