I’ve been to many dentists in my life, but none like this office… First off, this group is clean and well-kept. Everything is cutting edge and of the highest quality. The staff… amazing. Friendly, comforting, attentive, professional. The hygienists and assistants have been there for me through the ups and downs of my dental health. Dr. Zachary Grillo is the best. He is honest, detail-oriented, friendly, professional, superrr patient, knowledgeable, and he makes you feel like he cares. I’ve had a lot of dental trauma in my life and have seen many dentists in my life… but this is the office I’ll be sticking with. I feel like I’m family and not a money tree. If you’re looking for a dentist to take good care of you, give this office a call. You won’t regret it.

I have had a great fear of the dentist for many years. However, I recently found Grillo dental and I can’t even put into words how wonderful they are. I vocalized my fears and Dr. Grillo (both doctors, as I have seen them both) and all of their staff have been incredible. They are thorough, kind, comforting, and take the time to explain everything to you. They truly do everything they can to make your experience as comfortable as possible.

State of the art knowledge and equipment combined with caring, professional skill and accommodating staff make Grillo Dental an excellent choice. I have been a patient of Robert Grillo for decades. It is a pleasure to now work with Zack Grillo, who brings new energy to the practice. Keep up the good work!

I accompanied my brother for his first visit with Dr. Grillo, and our experience couldn’t have been better. He was prepared to meet and examine his new patient and spent a lot of time getting to know both of us. My brother’s exam was thorough, his needs were completely met and Dr. Grillo’s wise advice will be followed. The staff rounded out our complete satisfaction with this practice. It will be a pleasure to recommend Dr Grillo to other interested parties.

I had an infection in a molar that was extremely painful, and Dr. Z came in on a Sunday to help. I subsequently had the tooth pulled and an implant put in. Everyone at Grillo was and continues to be helpful and understanding. Dr. Z is always available, and followed up with me personally the evening after the implant was put in to make sure I was feeling okay. Jennifer is also incredibly kind, and always makes me feel comfortable in my appointments. Everyone at Grillo is ready to help and make your visit as easy as possible!

So happy to be a dental patient of Grillo Dental. Fine dentists, Dr. Robert Grillo and Dr. Zachary Grillo are personable, caring, committed to the best in dental care. The office setting is a welcoming environment, relaxing and comfortable. The entire facility is meticulously clean. Upon entering, the administrative staff are friendly, welcoming, knowledgeable and helpful. The dental hygienists are knowledgeable, skilled and kind. I am a dental patient of Dr. Zachary Grillo, who is an outstanding dentist. I have had same day crowns made in the office, that are beautiful, and recently, had a bridge made, that is better than any other I have had. Dr. Zachary’s attention to detail, meticulous dental work, being very talented and experienced, has brought my teeth and smile to a whole new level. So very grateful to be a dental patient at this dental practice. Thank you Dr. Zachary Grillo and Dr. Robert Grillo.

Quite pleasant. No selling of unnecessary services. Very careful examination. The doctors and staff are very amiable. I felt comfortable immediately. Dr. Robert Grillo examined me, but Dr. Zachary Grillo took the time to introduce himself, and even found the practice’s therapy dog, Jerry, so that I could meet him. I wish I could comment on actual dental work, but I was blessed with very good teeth. I know other patients who are extremely pleased with the work done, though!

My teeth are very important to me. I have an extreme fear of the dentist.The staff is wonderful. Office staff very professional and on top of what your insurance covers . The Doctors father and Son are also very professional as well as very concerned. They just make you feel like part of the family.

Grillo Dental has consistently proven to deliver state of the art, high quality care in an immaculate, hygienic, spa-like environment. Drs. Robert and Zachary Grillo have unquestionably restored my smile. I can honestly say that their meticulous technique is superbly gentle and pain-free (Dental Hygienists care included). The staff is very attentive, warm and always welcoming. They’ve treated my loved ones and me like family over the years. I have enthusiastically referred my friends and family to this FANTASTIC practice.

I had about 5 visits over a few months to take care of a lot of dental work I had been avoiding. Every visit the staff was friendly and helpful and Dr Grillo was professional and you can tell he cared about making you comfortable and took pride in his practice. The office is beautiful with high end and feels very welcoming. They are also very kid friendly here. This is the perfect dental practice and I highly recommend.

I am so happy I found this place!. I tend to pass out at the site of a needle so needless to say dental appt’s cause me a lot of anxiety. Dr. Zach was aware of my fear and made sure I was completely comfortable during my procedure. He even waited a little longer for my anti-anxiety medication to kick in rather than trying to rush through everything. The entire staff is so friendly and professional. The women at the front desk explain everything to you regarding billing and they are always so friendly. The office is beautiful and has a nice home feeling rather than a stale dental office. I saw Ann-Marie yesterday for my cleaning and she is so nice and gentle as well. I highly recommend this practice to anyone looking for a dentist.

I have been with the office since 1990. Dr. Grillo and his wonderful staff have seen me through many life changing events, both dental and personal. My teeth always seem to take the brunt of any major stress in my life, so there are hardly any dental procedures I haven’t had. Dr Grillo’s expert and compassionate care has resulted in permanent improvements in my mouth and a beautiful smile. I have always said I wish that everyone could go to his practice, and I have been traveling there from my home in Farmington for many years. Thank you all,

I can’t say enough good things about Grillo Dental! Their whole staff is so kind and explain things in ways anyone can understand. I don’t think there’s a dental office around better than these guys!

Janet Dexter Moberg (Source: Facebook)


Personable, attentive, professional, caring. This practice has gone a long way by doing what they do every day to mitigate my dentist anxiety that seemed to develop out of nowhere over the years. No one likes huge dental bills, least of all those of us on a fixed income. Yet caring for one’s teeth means caring for overall health, and both my husband and I have had lots of work done, so we speak from experience when we recommend this practice highly. It’s a beautiful office, but more importantly, a local team of dental professionals we’re grateful to know!

Amazing team all around. My comfort is always their utmost concern. They are friendly, personable, knowledgeable and great at their jobs. As long as Grillo Dental is around I will go here. Thank you for caring about your patients so thoroughly!

Great cleaning w AnneMarie. She’s is always friendly, warm, talkative , such a pleasure. Always knows when to suction your mouth, gives you a chance to speak during the cleaning. She never hurts your mouth or gums. she’s efficient and gets your teeth so squeaky clean. Dr Zack comes by to check everything out. He’s always so friendly, such sincere questions about my family life. He’s always smiling

I went into Grillo Dental as a New patient today and had a wonderful experience!  I know most people don’t use ” wonderful experience ” and  “dental office “in the same sentence but  I can absolutely share that happily!  I am a retired hygienist of 32 years and have seen a lot!  I was extremely impressed with the quality of care provided to me by Dr. Grillo and his dental assistant , Jennifer.  The office is state of the art in every way starting  the friendly and knowledgeable office staff  , Covid precautions, high tech equipment, and painless treatment! I am bringing my whole family over!  We are very happy to have found such a friendly and professional dental home!

I felt comfortable when I went for the evaluation. As dental work is costly even with “dental insurance”. I prolonged my next visit until there was pain. So I needed a root canal. Which in my opinion was almost painless. I had no pain after either. Then that evening Dr Grillo called to see how I was doing. I found my forever dentist. I’d recommend him always.

I have been going to Dr. Grillo for many, many years and would not consider going anywhere else! Dr. Grillo and his team are the best and always make you feel comfortable! They all take pride in everything they do!

Grillo Dental is hands down the best dentist I have ever been to. I will continue to come back and refer my family and friends. Such a friendly atmosphere. Everyone there really takes the time to get to know you. The fireplace in the waiting room is extremely relaxing. The hygienist took time to teach me all about gum decay and answered questions about teeth whitening and things I never felt comfortable to ask anywhere else. And of course there is Dr. Grillo who makes you feel right at home. You always know you’re in good hands with Grillo Dental!

I chose this dental office based on other reviews I read regarding the office. Having not been to the dentist in a while due to other health problems, a tooth needed work quickly. The office gave me strict instructions on what i needed to do beforehand. I followed these instructions and was able to get my tooth takes care of. I cried because I had finally found a dental group or doctor’s office I could trust. It was an amazing experience from the moment I checked in. Dr. Zachary Grillo is a profoundly professional dentist, and I’m so grateful to have chosen this office. Their kindness embraces you the entire time you are there.

Extremely happy with the work. I LIVE In Thailand and I have come home to the doctor do three implants for me. He is all about service and care of his patient.I am very happy with the doctor’s work.You can feel his expertise as he does his work. You know he knoes what he is doing.. i highly recommend him.

Janet Moberg (Source: Google)


I leave this amazing office feeling encouraged by the entire staff. Why? Because everyone, from the moment you walk in the door, is attentive to you. They are an example worth following of professional excellence as well as just down to earth good people to know. Look, dental problems can be serious and sometimes painful, right? Yes, they know it too, and my trust was earned when I was and continue to be made to feel like I matter. In an age where it seems like we’ve become cogs in a wheel in medicine, Grillo Dental stands out as a breath of fresh air in genuine positive regard for everyone. I’m so glad I chose them! Have a high regard for the entire Team.

My experiences with Grillo Dental have always been top notch!!!! They are the definition of your friendly neighborhood Dental office, and Sue (with whom I have had clean my teeth for 20 years) is the epitome of a thorough, hard-working dental hygienist. Please keep up the great work!!! #smalllocalbusinesses #loyalty

This past visit, Dr. Grillo offered to fill a cavity for me immediately so that I didn’t have to come back from college for a separate visit. Employees there are professional, conscious of your comfort, and very friendly. Also, I receive phone calls whenever it’s time to schedule my next appointment which makes it super easy to do so. I have been coming here since I was a kid, and confidently would recommend Grillo Dental 🙂

Grillo Dental is an excellent experience. Warmly welcomed by the office staff you can then be seated in an inviting waiting room. But not for long as most visits are timed perfectly. My hygienist visits with Maureen are always informative and comfortable. My visit today was based on her findings and communication with Dr. Zachary Grillo. This is my first visit with Dr. Zach. He is well versed in his profession and I immediately felt comfortable with his manner. He has a great smile and relaxing tone to his voice. He communicated very well about what we would be doing. He and Lee took care of the last of my silver fillings that were giving me issues. The time taken to do the repairs was just right. I was so relaxed that I actually napped a little while the work was being done. There was no discomfort at any time during the procedure. I must also say that the same can be said for Dr. Robert Grillo. He has always made me feel comfortable and the whole staff communicates well so that everything is taken care of properly. I highly recommend Grillo Dental for all of your dental needs.

Thanks to the tag team of Grillo and Grillo and with the help of their wonderful assistant Lee, I was able to arrive with a broken tooth and leave with a perfectly fitted crown. Always a wonderful (and painless) visit. Highly recommended!

They have a super staff. They can always get you and never make you wait. The hygienis are all very pleasant and well trained. Never a painful experience. The dentists are so nice and take special care of you and they do an exceptional job. I have had a ton of different kinds of procedures done here and have been with the practice for 14 yrs. I would suggest them to everyone. My teeth look and feel great!

For years, I had a pain in one of my molars. My dentist took x-rays and sent me to an endodontist bc he couldn’t find anything. I switched to Dr. Grillo. Within minutes, he took some special kind of image with a different kind of machine. He thought he saw a crack on the tooth. While I was still sitting there he sent the X-ray to another specialist to confirm. Before I left, the other guy confirmed. It was determined that I needed an implant instead of a crown. Then, he sent me to the best around. Four yrs later, the implant holds strong. So, in summary, years of complaints with the first dentist., 15 minutes with Dr. Grillo. Problem solved. I switched dentists to Dr. Grillo and have been happy ever since.

This was my initial visit to Grillo Dental and I was very impressed with the office, staff very friendly and doctor extremely thorough in his explanation of what he saw and next steps. I definitely would recommend Grillo Dental based on my first visit.
