One of the most refreshing, incredible dental experiences I've ever had in my life. Dr Brownstein's staff goes above and beyond to make sure you are comfortable. Dr. Brownstein himself is a true professional , never had an experience with my teeth that was truly painless like this. Thank you guys!

Dr. Brownstein & his staff are wonderful! I would highly recommend them! This was my first root canal & he explained everything to put me at ease. A big thanks also to Cheryl for being able to get me an appointment so quickly. If you need an endodontist, this is where you should go!

I can't say enough positives about Dr. Brownstein. When I learned I needed a root canal, I was so scared but to learn I needed it two, I was petrified. Dr. B was highly recommended by my dentist so I made the decision to book the appointment with him and have faith I'd be in good hands. I AM SO HAPPY I did! In the first few minutes of meeting him, my nerves were calm and I felt confident I'd be just fine with little to no discomfort. He split the visit in two as a safety measure to ensure no post op infection would incur. I agreed that I'd rather be proactive especially with my trepidation. From start to finish, I had a great experience and although I hope another root canal is not in my future, I would only go to Dr. Brownstein! Truly top notch and cares about his patients. Not that it matters but I would like to add that my insurance was being difficult and Dr. B took the time even though it's not his responsibility to assist me in making sure it was covered. Thank you, Dr. Brownstein!

I needed a root canal for a tooth that was becoming infected. Cheryl was most pleasant to deal with and got me a much needed appointment without delay. Dr. Brownstein put me at ease right away. He has a light touch and was able to do this root canal in one day! Never before have I had a root canal with so little hassle. I highly recommend Dr. Brownstein!

I had a good experience with Dr. Brownstein. He was very knowledgeable about root canals. He made sure I was comfortable by asking me if I was okay. I'm going to see him next week for my second part of the root canal procedure.

I hope William G. Brownstein improved his skills since I went to him years ago. He did a root canal on the WRONG tooth, a perfectly healthy tooth! It was my very first root canal and I was in severe pain. Dr. Brownstein had just gotten his latest digital x-ray technology and had read it wrong! When I left the office and the numbing wore off, my tooth still hurt severely. Dr. Brownstein even admitted to the error and said he would do the right one for free. He had me sign a waiver. Both teeth he did now needed to be extracted! I'll never forget the comment he said when I asked why I all of a sudden need a root canal at 42 years old. He said "That's what happens when you're middle aged". If you want to trust him, go ahead, it's your teeth, your mouth. In reply to the office's response: It was many years ago since Dr, Brownstein claimed at the time he had not used that machine yet and I obviously was the guinea pig. Yes, this review is present now since feedback wasn't available then. I wanted to tell others of the long term end results of Brownstein's work and ethical tactics. I hoped he had improved since I lost a healthy tooth because of him. Look up your records, invoices and waviers if you question my statement. I have no reason to write this other than reasons of the truth. And who are you writing in behalf of the dentist? How can you state what Dr. Brownstein would NEVER do?

Dr. Bill did a GREAT job with my root canal. Very professional, and nice office. Staff was great as well. Spoke to Cheryl on Monday, and was in the chair on Tuesday! Thanks again for everything!

I had a dental emergency after receiving a root canal here and Cheryl gave me a vague answer telling me to go to my general dentist first, but that makes no sense since brownstein worked on it last. Seemed like she just didn't want to deal with me and show me that she doesn't understand patient care. I think brownstein is a good dentist but staff (cheryl) not so much...
