"I switched to cornerstone dental about 4 years ago from another dentistry and have been amazed with the team as a whole. Becky and Dr. O’Brien have been nothing short of incredible with keeping my smile healthy and providing insight on other mouth care that I wouldn’t have received at my previous dental office. Thank you, Cornerstone!"
-Brandon E
"Hygienist was knowledgeable, pleasant and informative. Dr. O'Brien was great as usual! Both gave me a thorough exam. I wouldn’t give my business to any other office! Thank you!"

"I have had multiple visits with cornerstone dental and every time has been an effective use of my time. I’m writing a review to let people know that Dr. Portnoff and staff are the best you will find for your dental needs. I have referred people here and will continue to do so."

"To say that I have enjoyed every appointment I've had at Cornerstone Dental might sound strange, but it's genuinely true. The office is clean and modern and inviting, with water and coffee available in the waiting room along with a large variety of reading material. More importantly, the staff is exceptional. I have never encountered a more kind and welcoming group of employees at ANY doctors/dental office. The women at the front desk are simply the best. Always there to check you in or out with a smile on their faces. The dental staff is informative and gentle. I never have once felt like I was being "upsold" for any services, as I have at other dental offices I've been to. The hygienists are also very intelligent and help you to feel comfortable and calm throughout your appointment. I truly can't say enough about this place. If you're looking for great Dental Care, i HIGHLY recommend Cornerstone."

A welcoming greeting when I entered the reception area. The whole office atmosphere was comfortable, clean and pleasant. CDC staff members were very professional, informative, confident and most of all friendly. I truly felt relaxed and at ease in the chair!

This was my first time meeting Dr. O'Brien. She was an absolute pleasure. She listened to my problem and came up with a solution and was extremely understanding. It further reinforced how happy I am with the care I receive at your office.

I'm a patient of Dr. Lynch and I see why she choose to join/merge with this office! This was my first time in the new office and EVERYONE could not have been more pleasant. I absolutely love the design/decor of the office.

Why wait until 2:30, make your appointment now
I have been a patient here for several years now, my wife as well, and we wouldn't think of going anywhere else. Everyone is friendly, professional, and, unlike many doctor's offices, fully aware of how important your time is. You don't feel like you're visiting the dentist, more like you're dropping in on friends.

Consistent High Quality & Comfort
I have been going to this dental office for many years now. I am happy to say that I have never had to wait more than 5 or 10 minutes to be seen, and I am always greeted with a smile and treated in a warm manner that takes away any trepidation I might have. The staff is always up to date in their knowledge and always concerned with helping me acheive excellent dental health. I highly recommend this practice for anyone considering a dentist in the Metrowest area.

Super-dentist and super office
Simpy put, I would not be going to the dentist if your office did not exist. I have phobia about dentist complicated by a history of poor care. Only by developing a long-term relationship with super-understanding, caring, careful people, am I able to go to the dentist at all. My kids and whole family love you and we would not be there if there was a single problem. We have all five come regularly since you opened and agree you are the best dentist we have ever had. (Tanya deserves special mention because she even reminds me to take medicine the day before I come in!) This is a great dentist and she is surrounded by great people. I cannot rate you highly enough.

Goodie Bag
Love, love, love the citrus lip gloss in my goodie bag. One of the best promotional giveaways I have seen. May have to get my teeth cleaned very month. (Then I won't have to floss - LOL!)

Best Dental Office...not just in Westborough!
Dr. Traci and her staff are friendly, kind, compassionate. I have tried other dental offices and they cannot compare to the excellent treatment found here.
