I saw DR Buck while I was in the hospital. I liked his approach and manner and asked if he would take me on as a patient. He agreed. After that, I was unable to connect. The office management is a nightmare. It doesn't matter if you have good docs if the patients do not have access. Very disappointed in the practice.
