I chose to specialize in Hand and Upper Extremity because this is the most elegant instrument that I know exists. Our hands are so versatile and they allow us to do so many different things. We have this fine sense in our fingertips that we instantly know what we are feeling and we can adapt without even thinking about it. It’s not only mechanical – there is something deeply personal about our hands. These are what we use to hold a loved one’s hand, hug our kids or make a personalized pizza with them! I am committed to seeing you thrive and it is my privilege to be entrusted with your care.” – Dr. Kolahi
