What could be improved
    Dr. Derleth is not only a very highly qualified outstanding doctor, but also has so much compassion patience and sensitivity for his patients. He has been my mom’s gastroenterologist for about five years. He is very calming and patient. He saw my mom on time and wasn't rushing to get to his next appointment. I highly recommend him. A great doctor -- competent and caring! He is truly the best!
