At Chestnut Family Dental our Doctors are committed to providing the very best in general and cosmetic dental care. Our goal is to treat our patients in a professional yet comfortable environment in the most efficient and effective manner possible.

Our dental practice was established over 90 years ago in a small office on Elm St. in downtown Manchester, NH. In the mid 1960s, the office was relocated to Middle St. in Manchester. Our current location, established in the early 1970s, is in an historic 100 plus year old Victorian home. Dr. DeLeo became the third owner of the practice in 2001 and Chestnut Family Dental was born. Dr. Mercado joined her husband, Dr. DeLeo, in 2004. Chestnut Family Dental is located in the prestigious North End of Manchester amongst many other charming Victorian homes housing various commercial businesses. We are easily accessible from both Interstate 93 and 293 and provide ample and convenient on/off street parking.

Once you enter our beautiful building, you will see how old meets new, with original, intricate woodwork combined with the most up-to-date technology in dentistry. The Chestnut Family Dental team provides our patients with the Gold Standard in dental care through our current and ever-advancing knowledge of dentistry and continuing education.

We welcome all patients entering into our practice. Soft music and availability of coffee and bottled water provide our patients with a relaxed dental atmosphere. Our friendly front desk staff is always ready to help with any questions or concerns which may arise with your dental care. We strive to accommodate any special needs that our patients may have and approach each patient with respect and acceptance. As an office, we view community service as both personal and professional priorities. For example: We provide over 100 oral health kits to the New Horizons Homeless Shelter every month. We also contribute yearly to the Union Leader Santa Fund and provide goods to less fortunate families during the holiday season.
