    Dr. Buckle seems to care a lot about his patients and goes out of his way to help them in non-medical issues. We are self-pay and when we turned down the chemo infusion because of cost he offered us the oral medication. That is also expensive but he told us about Good Rx and found a coupon for us that saves us thousands of dollars every session
