Dr. Was Hours late to procedure.
His office refused to do a follow up appointment with me. Him and Dr. Class. Talk about “Do No Harm””. Treat me, prescribe Rx, tell me to call and set appointment. Then dump me. Unprofessional and very unethical.

I’ve been a patient for almost 7 years. And I’ve referred several people to him.
Like me, they have been 100% satisfied
with his genuine concern, care and advice. As a medical professional, he’s the best listener of any I’ve had.

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.
