William J Quest, Ms DDS
William J. Quest and Diane Johnson, a respected provider of orthodontic care in the communities of Mooresville, Plainfield/Avon, Camby, Monrovia, Martinsville, and Danville. Our practice's top priority is to provide you with the highest quality orthodontic care in a friendly, comfortable environment.

We utilize the latest technological advances in the industry, such as clear ceramic braces and Invisalign, along with the latest in computer technology (digital imaging and advanced computer graphics) to ensure that you receive the most effective care possible. We recognize that every patient has different needs, and we pride ourselves in the courteous service we deliver to each person who walks through our doors.
Services
Dr. Quest believes that orthodontics is a valuable part of a person's overall healthcare and is dedicated to creating outstanding smiles for his patients, using the latest technology available. Dr. Quest is an accredited orthodontist. This means that he is a dental specialist who has completed an advanced post-doctoral course, accredited by the American Dental Association, of at least two academic years in the specialty of orthodontics.
Our goal is to allow you to be seen on time for your appointment, do all necessary scheduled treatments, make appointments as stress free for you as possible and to minimize interruptions to your busy schedule. We understand that everyone has important obligations throughout the day and that your time is very valuable.
The cost of your orthodontic treatment may vary depending on your individual needs and treatment plan. Our staff will discuss with you the cost of your treatment and your payment plan options so you can make the best choice for you, and your smile. It is our mission to provide you with affordable, high-quality treatment that fits your budget!
An orthodontist is a dental specialist in the diagnosis, prevention and treatment of dental and facial irregularities. Orthodontists must first attend college, followed by a four-year graduate dental program at a university level dental school accredited by the American Dental Association (ADA).

They must then successfully complete an additional two to three-year residency program of advanced dental education in orthodontics accredited by the ADA.Only dentists who have successfully completed this advanced specialty education may become an orthodontist. It is usually difficult for you to determine if treatment is necessary because there are many problems that can occur even though the front teeth look straight.
Fear of the unknown is human nature and some nervousness is to be expected prior to starting orthodontic treatment. Your first visit to our office is a time for us to get to know you and determine what your main concerns are. We will ease your fears by giving you as much information as needed to help you feel comfortable.

My daughter has anxiety and a slight learning disability and they are wonderful with her! All the ladies and Mr. Johnson are wonderful people! They are great at their job and make everyone feel welcome. If you or your child(ren) need braces, this is the best place to go.

The two DR'S here are wonderful. I have used them for over 10 years. Sad to say though their receptionist Kelsey is VERY rude. Enought to make me not want to send anymore business their way! Don't get a customer service job if you can't speak to people nicely!

I remember enjoying the atmosphere as a kid, but recently found out that I have to get a root canal because of something they did incorrectly when I had braces 8 years ago. The issue causing my root canal has been gradually getting worse and worse and it all could have been resolved if they didnt go with a "quick fix" solution all those years ago.
Also, every visit I've had there, they've told me that I HAVE to get my wisdom teeth removed (and even refused my service at my last appointment UNTIL I get them removed) yet every other dental professional I've seen has told me that it's not necessary

This office is amazing. I have a daughter in braces now and another daughter getting them on Thursday. The staff is the most friendly staff I've ever come across in the medical field. They treat everyone who walks in the door like family and always make you feel welcome. You are making the best choice in your childs orthodontic needs by picking this office.

They do good work, but they change their hours often and also will close on some weeks/days making very difficult to schedule. There are two main doctors a several assistants. No reason to not have a steady set schedule with a skeleton crew. Two of the three times my daughter broke her retainer I called to schedule and they were closed for the week or a few days. Yet they still made a big deal about her going so long without a retainer. I cant get a new retainer if you are not open. My son needs braces. We are going elsewhere when its time.

This place is awesome! It was so nice going in and knowing everyone, while everyone there knows your name and talks to you. The staff there instantly becomes like family to their patients, which is why they aren't afraid to tell you how your teeth are, no matter what. I highly recommend this place for anyone willing to put the time and effort into their teeth.

Staff was good but they work with a lot of highschoolers and teens so one of the women working there seemed to talk down to me throughout my 14 months with them. Otherwise my teeth look great. Very happy with that
