Meet Our Orthodontist in Littleton, Plymouth, NH & St. Johnsbury, VT

Dr. Hiller started his first specialty of orthodontics practices in Conway and Berlin in 1983 and currently has practices in the communities of Littleton, Plymouth and St Johnsbury. Dr. Hiller is as passionate about his work today as he was over four decades ago. He is still known and loved for his wonderful sense of humor, quality treatment and warm personality.

“The most rewarding part about devoting my professional life to orthodontics is that I have the privilege of improving a person’s confidence and self-esteem through their new smile,” Dr. Hiller says.

Dr. Hiller also enjoys golfing, viticulture, hiking and boating and is an avid Boston sports fan. He and Pat, his wife of 47 + years, have four children, five outstanding grandsons and six beautiful granddaughters (thousands of pictures available!). A northern NH resident by choice, Dr. Hiller has been an involved community member serving on many boards and committees over his career.

As a very involved member of his professional associations, he has served as Trustee to the New Hampshire Dental Society; President of the North Country Dental Society, President of the Northeastern Society of Orthodontists; member of the Sports Medicine Committee of the NH Interscholastic Athletic Association (NHIAA) as well as a Chairman of the Council on Governmental Affairs of the American Association of Orthodontists (AAO) and is the current Speaker of the House of Delegates of the AAO.

Education
Dr. Hiller was born and reared in Nanticoke, a small town in northeastern Pennsylvania. He attended Rensselaer Polytechnic Institute where he earned a Bachelor of Science in Biology; Temple University School of Dentistry where he earned both a Doctor of Dental Surgery (1981) and a Master of Science in Dentistry and certificate of specialization in orthodontics (1983).

Continuing Education
By participating in more than double the required hours, Dr. Hiller is adamant to stay abreast of all the developments and provide the most advanced care possible. His memberships make it possible for him to continue his education and grow his knowledge and skill as an orthodontist. He is currently an Invisalign® Platinum Plus Provider.

“The many wedding and graduation photos as well as thank you notes from both current and past patients remind me of the impact I have made on their lives.” – Dr. Dennis Hiller
