An orthodontist friend recommended Dr. Allan McQuarrie, and after just a couple of visits, he transformed my smile and boosted my confidence. His calm demeanor and clear communication made me feel at ease, and the office staff was incredibly supportive and friendly. I couldn't be happier with my experience and highly recommend Dr. McQuarrie to anyone seeking a dedicated and caring dentist." - John N.

  • "Dr. Machell has been my dentist for over 19 years. I felt like I was one of the lucky ones to be able to have him as my dentist. His disposition and expertise in dentistry are superb! I knew Dr. Machell was looking for a replacement and wondered how he would find someone as talented as him. However, Dr. Allan McQuarrie is truly fantastic. He has Dr. Machell‘s same gentle personality, disposition, and expertise, along with a passion for using all natural products. I am beyond thrilled with how carefully Dr. Machell found the perfect replacement, as Dr. McQuarrie is a wonderful dentist. " - Terry W.

  • "Since moving to New Hampshire in 1988, I've been a patient at John Machell's dental practice in Nashua for 36 years and have consistently received exceptional care. The staff, from the front desk to the dentists, are professional, caring, and highly competent. Despite my aversion to dental procedures, everyone has been reassuring and thoughtful. I am happy to share my experiences with Dr. McQuarrie, the newest addition to the practice, have been just as positive. I feel fortunate to be part of this dental family." - Mary W.
