I really love the dental office and everyone is friendly and courteous. The office is clean and the best dental hygienist I’ve ever had is Karen .. both of my children go there as well and they really enjoy it.
From the moment I step in the door, I am treated like a welcomed guest, especially appreciated when it is a dentist office you are entering. It was a hygiene visit and it went very very well. Karen was thorough, professional and addressed all my questions and concerns about my teeth in a knowledgable and concerned way. I would recommend Saw Mill Dental to all my friends!!
They made me feel most comfortable and walked me through everything. Sawmill dental is the only place i will go for dental work in the future
There’s not enough I can say about Dr. Friedman and all his staff. Everyone is amazing. Professional and courteous. I moved over an hour away but trusting my children’s care to another dental office was not an option. I highly recommend Saw Mill Dental for all your dental needs. I’d give them 10 stars if I could!
EVERYONE is so friendly. I’ve been going to this office for over 10 years and even though I have moved upstate, I still go to Saw Mill Dental.
I have to say that I was VERY VERY happy with the service, and care. Everyone in the office treated me with kindness, care and professionalism. I am very afraid of the dentist chair. The doctor made me feel very comfortable. I need two root canals and a wisdom tooth pulled, so I need serious work. They gave me a good price. Not one of the other three dentist that I went to offered me any hope with…
from setting up my first appointment on the phone. To my first appointment at the clinic. Everyone one i encountered, from the front desk to the examination room , treated me with the upmost respect and courtesy . They took xrays and explained to me throughly the treatment plan and my options. Honestly speaking it couldn’t have went any smoother . Above excellent!
This was my first time at Saw Mill Dental and everyone there was very courteous and professional. They made me feel calm since I am always nervous when I visit the dentist. The hygienist did a very thorough job and the dentist explained everything to me in great detail. I would definitely recommend Saw Mill Dental to anyone looking for a dentist to go to.
I have been going to Saw Mill Dental since my daughter was 6 years old………she is now 36 years old…I believe that, in itself, says a great deal about the entire team at Saw Mill Dental!!! Keep up the great work!!!!
I really appreciate the excellent service and care your office provided me I also look forward to my next visit on Friday I know you’ll do your best to accommodate my situation Best Regards Kevin
My experience was Very Calm and Painless. Both the doctors and office staff are very caring and ready to make you feel at ease and answer any concerns the patience/myself may have. Thank You!!
