Dr. John P Pietrasik

DO NOT GO HERE! Originally saw Dr. Ramos and she was very unprofessional and open made comments about how my cavity filling wasn't properly done but said " if it's not broken don't fix it" not even 24 hour later and the filling fell out. When back to get it fixed and about three weeks later it fell out.

Dr Ramos was awesome! She took her time to fix my gap between my teeth and made them look natural and perfect. Her assistant Rachel was also amazing. They were both very nice to talk to and made the appointment enjoyable. The whole staff is great!

I just went to DMD Katherine Tyros for 3 minutes of "Limited Oral Evaluation" with complain of partially chipped filling and she professionally charged me $109 for advising that it does not require any re-fill. They know how to value their time, so I will look for someone that will value mine.

Love this dental office. The hours are so convenient - I usually get an appointment in the evening when the kids are in bed. They give straight forward advice, do honest work, and never make you feel like you are being sold a bill of goods. I have been to many dentist offices over the years and some of them were quite predatory. Walking into this practice was such a relief- the quickly debunked what I had heard in other places and saved me quite a lot of money.

It has been many years now, and time has proved their advice was the best. As an additional bonus, all the hygienists that I have had there over the years have been friendly and interesting as well as skilled and that is important as they are the people you spend the most time with. The dentists and hygienists seem to have a mutually respectful relationship which also inspires confidence and adds to a more positive experience.

Happy to find a new dentist. The dentist I had seen for the past 40 years retired. I couldn't be more pleased with the services received yesterday at Chelmsford Dental Associates. Everyone there was very pleasant and professional. The staff took the time to make sure that everything was very clean before I was examined and the dentist was very thorough in his examination; he even cleaned my teeth himself because it was my first time as a patient.

My appointment went very well. I waited in the car until it was time to go into the office. Everyone was welcoming and I felt very safe. My hygienist was efficient and professional and very pleasant. Dr. Pietrasik was very thorough and gentle. I am very pleased with my visit and I highly recommend this practice to anyone in the Chelmsford area.

I (personally) hate going to the dentist. The tools, the noises, the dreaded fluoride. pretty much everything. Kelly changed my opinion in one visit. She was super nice and made the overall experience not so bad - which may not seem like a compliment but if you know my strong dislike for the dentist, it's HUGE. She told me what she was going to do before she did it, made pleasant conversation and before I knew it. it was over. I will without a doubt request her every time I go. Thanks Kelly!

I have been going to Chelmsford Dental Associates for many years and have been treated so well by the professional staff in every department. I recently went to the office for my regular cleaning and felt completely safe with excellent protocols in place. I highly recommend this office to anyone, especially if they are anxious about dental work. Well done CDA!

Chelmsford Dental Associates is the best dental practice I have ever used. The office and its staff on every level is marked by its friendliness, accomodation to emergencies, and professionalism. I have been a patient of Dr. Tyros for the whole time. I cannot praise her for her skill and manner. Her supporting staff and the dental hygienists and assistants do a great job in maintaining my oral health. They are extremely careful and friendly and I have gotten to know several of them, such as Melissa, Erin, Kayleigh, over a number of years. Very satisfied indeed.

Excellent service! All staff are friendly and compassionate about their jobs. The dentist and all technicians took the time to explain everything in great detail. I also felt very safe coming to this office during COVID pandemic. All staff had appropriate PPE in use and followed clean or sterile protocol when needed. I've seen a lot of bad dentists, so I was relieved to finally find a good one in Lowell! 10/10 would recommend!
