Great experience! Pain free! I highly recommend George Manthas, DDS if you're looking for a dentist in the area.

Good medical practice but confusing information about alternatives that ended up to an overpriced treatment.

The office staff is incompetent and can’t keep track of appointments they scheduled and confirmed. As a result I am going to another Dentist.

Dentist was great, woman working the front desk was not pleasant at all. The way she received me and her overall attitude may deter me from going back. I did not feel welcome at all.

Excellent dentist
September 19, 2017Michael K.Verified patient
The doctor and his dental hygienist were both great. The assistant at the front desk was not the nicest but the rest of the team made up for it.

The dentist was great & the cleaning felt thorough. My one complaint was the receptionist. She was very short and almost rude.
May 25, 2017Initials hidden
Dr. Manthas is a nice man with a kind heart. However, he never actually looked at my teeth. His assistant took care of the cleaning, which was complete in 20 minutes. She flossed one quadrant of my mouth and then said I was done. Admittedly, I'm on an HMO insurance plan, and perhaps this was part of the reason for the rushed service, but this certainly was a different experience than I have received from other dentists.
Michael G.Verified patient
Every dentist I have been to after Dentist Manthas has told me my filings were not done properly. The infection continued to spread and I now have to get surgery. Other than that he is really friendly and great guy.

Amazing dentist!
December 8, 2016Briana W.Verified patient
Had a great experience with Dr. Manthas as usual. Zocdoc listed him as accepting my new insurance when I scheduled the appointment but he was unable to accept it when I arrived. Thankfully it was only a cleaning, but I had to cover the cleaning on my own since he wouldn't accept my insurance.
Always a great experience, but call to verify if your insurance is covered because Zocdoc listing may not be accurate.
December 6, 2016Geoffrey E.Verified patient
Although Dr. Manthas was very polite, he spent a total of about 5-6 minutes cleaning my teeth - there was NO hygienist who cleaned my teeth. Upon asking why my visit so quick, and if everything was okay, I was told that the equipment being used made the cleaning procedure more efficient, and that my teeth were great. I would prefer a deeper clean since I usually go to the dentist about once a year.
December 3, 2016Stavros L.Verified patient
That was my first time here; highly recommend him. Very polite, helpful and straight to the point. He really wants to help the patients.
July 11, 2016Nicolaos I.Verified patient
All the time hi is great
Graciela S.Verified patient
Dr. Manthas was able to identify the cause of my discomfort and treat it quickly. He was very nice and took the time to explain my options to me. I will be returning to him in the future.
July 16, 2016David S.Verified patient
George was awesome. Told me the dentist that insisted I get my teeth filled was being dramatic and probably trying to get more business from me. He fixed up one issue and gave me a full cleaning and gave me advice for how to manage the tiny chip in my tooth. Checked with my insurance and he only billed me for what he did.
Felt like he truly had my best interest at heart. Would definitely recommend.
May 13, 2016Brian B.Verified patient
Incredibly nice dentist. He gave clear feedback and was very personable. He's been in the neighborhood for a while and makes you feel comfortable. No complaints at all.

Awesome! So fast and efficient and super nice!
March 11, 2016Holly H.Verified patient
Allways is good
March 14, 2016Graciela S.Verified patient
I went here for a cleaning after my insurance changed and forced me to find a new provider. I'm so happy to have found an efficient, straight-forward, local dentist. I highly recommend Dr. Manthas.

Got my extras done and cleaning done all within 45 min. This dentist is not looking to over charge he just wants you to have good teeth. He is our new dentist for sure.
