Great visit with Dr Herr who I’ve been a patient of for over 20 some years. Knowledgeable and listens then asks questions and summarizes and then gives his opinion and recommendations. Easy to understand and makes time for you.

I have been a patient of Dr. Herr for the last 6-8 years and he is one of my very favorite doctors. He is excellent at what he does, he is a great guy, and he is a man of his word. He has been honest with me from the first time I saw him. I have seen a lot of doctors and Dr. Herr is right at the top. I can't recommend him highly enough.

Dr. Herr has been in practice for over 40 years and knows his stuff. He was prompt, courteous, friendly and took the time necessary to evaluate my problem. His assistant/nurse was the most friendly, kind and caring I've ever encountered.

I saw Dr. Herr for gastroinestinal issues. He did not take my complaints seriously, did not ask me any relevant questions and told me I was fine. I continued having symptoms, went to a different dr. who asked me specific questions, ordered a simple test and discovered I had a very serious bacterial infection. Please do not go to Dr. Herr under any circumstances.

Arrived at the waiting room on time. There were 5 patients in front of me. After one hour I asked the gal at the front desk for the expected wait time. She about shot me. Finally got in to see Dr. Herr. Loved him. However I wont go back again due to wait time and rude staff.
