Patient Reviews
Nov 14, 2021
Jim Markowitz saved our son. When we arrived in his office our 12-year-old son was just 58 pounds and suffering painful daily stomach aches. Our pediatricians completely missed the diagnosis and ignored our pleas for help. So our son hadn't grown for about five years -- since he was about 7. As parents, we were at our wits end trying to discover what was happening. The minute we sat down in Dr. Markowitz's office he looked at our son and said, "I know why you have stomach aches. I know why you're not growing. And I'm going to help you feel better." And he did, indeed, help our son feel better. Thank goodness for Dr. Jim Markowitz.
