Dr. Donald John Zeller, MD

Dr Zeller is my favorite and best doctor that I have ever had. He also is excellent with making recommendations to specialists. Basically if Dr Zeller refers me to another doctor I will get fit into the new docs schedule within a week. He is clearly very well thought of by his peers as well as patients. If I got my way he would be practicing until he is 100 years old. I followed him to Devon from Phoenixville and would follow him elsewhere if need be. He is really smart, kind and friendly. He always is right with diagnosis so I never doubt him. He always takes the time himself to call with test results and he always returns messages. I give him a 10+ in all areas of practice.

So happy he's not practicing at Devon Family Practice any longer.

I highly recommend Dr. Zeller to anyone seeking an excellent primary physician. He is very kind, concerned and extremely professional. Never do you feel rushed or is your issue minimized in any way. Dr. Zeller made a few recommendations as to lifestyle changes I could make to improve my overall health and they were right on the mark. You immediately gain a full sense of confidence in any diagnosis he might make and the few times I was ill his course of treatment was exactly what I needed. Dr. Zeller's professionalism extends to the entire office as all the folks there are most efficient, pleasant and polite. That's an added bonus

Dr. Zeller has been my primary care doctor for the past 8 years now. Great service, always takes the time to explain things in laymans terms and is accessible for urgent appointments.

Doc Z has been my family physician for around a decade's time and has always been available when need be. He remembers his patient's names and what they share about their personal life. I have never felt rushed or brushed aside by my doctor. He came into the medical profession for all the right reasons and still lives by those ethics in practice.

Dr. Zeller has been my family's primary care physician for 7 years. He is always caring, conscientious and professional. He greets his patients with a smile, listens carefully to their concerns and after an examination, he takes the time to explain his diagnosis and answer questions. All family practice physicians should be so good!!
