I believe Dr. Detweiler is a genius. His knowledge of almost all health issues bypasses all other doctors I've seen. He has saved my life numerous times. He listens carefully, and looks at his patients as a whole. He really cares. Anyone under his care is very lucky!

Dr Detwiler has been treating my mom and I over the past 20 years. I dare not even think about where I would be today if it weren't for a very compassionate nurse who recommended Dr Detweiler to me. I am grateful everyday to that nurse, because had it not been for her, we would have NEVER gotten the proper treatment to get well. I can honestly say that Dr Detweiler is very dedicated to his practice and his patients.  In my opinion, I believe he has stepped out against the status pro quo of modern medicine, to be able to gi... read more

I was referred to Dr Detweiler through my Primary doctor. He spends a lot of time with you and he makes sure that you understand everything. He ordered a few simple tests that I could do at home and he found what the problem was. He is a very intelligent individual and excellent at what he does. If you don't want to treat your problems with traditional medicines and choose to do herbs he definitely is the doctor to see. He has no problem in prescribing traditional medicines but I chose the herbs. He is an excellent doctor. ... read more

This Doctor saved my life more than once, and has improved the quality of my life. I would strongly reccomend taking any suggestion he makes. His staff goes out of the way to accommodate your schedule, an budget.I would trust his judgment and follow any recommendations before any other Dr. If he doesnt have the answer he will not rest until he gets the answer or tell you there is no answer..I really can't think of a man I respect more or woman that has treated me. He is brutally honest and direct,and no agenda other than com... read more

Update: Unfortunately, I was trying to give the Doctor the benefit of the doubt in my original review by giving his office more than one star, but based on his response which is not remorseful at all I cannot even offer him that. As soon as I picked up the phone with his receptionist I said I believe there was a misunderstanding and you mistook me for a female on my voicemail and my name is actually Christopher as pleasantly as possible. I was explicit in this so we could proceed normally. She then proceeded to take my infor... read more
