He is truly and amazing doctor, he explains everything he is doing, draws pictures if he needs to for your to understand exactly what he is saying. He spends a lot of time with his patients and make sure you don't leave the practice feeling confused. Sometimes the wait can be a little difficult (20-35mins), but you know that the same level and time you received, everyone else did also. His staff is very caring and knowledgeable; spending time with you, answering any questions and going out of the way to help.

My family has been going to Dr Lown for many years. He is extremely intelligent and has a warm personality. He gives you all the time you need and is a superb diagnostician. I always feel that he is genuinely interested in my well being. I highly recommend him. He also picks wonderful assistants to work with him.

Have been going to him for almost 20 years. Tried a couple of others in between and are not as good as him-not even close. He is thorough, answers questions clearly and does not rush. H

I don't undersatnd the "rude" comments. I have seen Dr. Lown a few times and have never experienced him being rude to me or anyone else. He has helped me a lot with my sleep issues- he is a busy man but that's the way it is in the medical field these days.
