Hear It From Our Patients!

I love Chestnut Family Dental, not only for Drs. DeLeo and Mercado, along with their entire staff, are dedicated to patient care. They are compassionate and care deeply for their patients. I would highly recommend them as a family dentistry group.


I've been with Chestnut Family Dental for over 40 years. Moved to Plymouth but continue to make the bi-annual trek. They are the best both as professionals and as people helping to keep us healthy. Jim, Daphne, and the complete staff are 5 🌟


Dr. Mercado and her staff are hands-down the best dental practice I’ve ever found. State-of-the-art, caring, professional and friendly. Didn’t know it was possible to get it all in one dental office!


Dr. DeLeo and Dr. Mercado are both the most genuine people and the most amazing dentists I've ever experienced. All of the staff at Chestnut Family Dental from the front desk to the hygienists/assistants, go above and beyond to make sure you're comfortable and have a pleasant experience. They are all so friendly and great with kids! Highly recommend this office


I have been going to Chestnut Family Dental for many years. I feel very comfortable there. Dr Mercado goes out of her way to make sure I understand what treatment I will be receiving, and I feel absolutely safe in her hands. The staff is very professional, and they work hard to make my experience pleasant. And as an added bonus, when I have an appointment, I usually come away with a great book recommendation...Dr. Mercado loves to read!


Caring, professional, attentive to your individual dental health is how I describe the staff at Chestnut Family Dental. They are the best dental practice if you need a no stress, no nonsense, quality dental experience!!


The people at Chestnut Dental are courteous, professional, and friendly. From the moment you are greeted upon arrival, throughout your dental procedure and checkout, all the people at Chestnut Dental make your visit a very good experience. They truly care about the comfort and wellbeing of their patients. There is no better staff and people than Chestnut Dental.
Highly recommended!


Chestnut Family Dental is just what the practice is all about...how you are treated the minute you walk through the door. Everyone , from the office staff to the highly competent dentists, treat you with kindness and respect. Dr. James DeLeo has been my dentist for over twenty + years. He has continued to study and implement the newest dental techniques available. I have been able to have several beautiful crowns completed in his office, in one visit, and absolutely no problems. This practice is a great place to become part of a family. Thanks


Wonderful experience at Chestnut Family Dental this morning. The staff is professional and friendly. I know after each visit I am receiving the best care!


Chestnut Family Dental always treats me like family. They are all very patient, caring & explain everything so that I always feel at ease no matter what the visit is for. They are the only practice I recommend to friends & family.


Been going to Chestnut Family Dental for many, many years. It has always been a wonderful experience. The front desk staff has always been unfailingly pleasant and helpful. Drs Mercado and DeLeo are wonderful, caring, and thoroughly gifted professionals. The office always has the latest equipment and they utilize the most modern dental techniques.


The staff and Dr Jim are always top-notch. Dare I admit that I enjoy visiting the Dentist? It’s true!


My wife and I have been going to Chestnut Dental for many years now. We moved to Portsmouth 12 years ago and still come back for all our dental work. They’re the best!


I’ve been to a few offices, and this has by far been my favorite! Dr. DeLeo makes sure that you’re comfortable throughout your procedures and you can tell he truly cares about his patients as well as his staff. Highly recommend this office!


Dr. DeLeo and Mercado, and all their staff are highly qualified, knowledgeable, caring and friendly (as well as being very gentle). Their team is all about preventative dentistry and constantly informing me of the best ways to care for my teeth and gums. I highly recommend Chestnut Family Dental for all ages.
