Excellent Doctor; Superb office staff and setting.
My son is extremely happy to see Dr Marston as he feels listened to, that no unnecessary dental work is undertaken and when he was struggling with his space saver (he got angry and broke one), Dr Marston was really sympathetic and offered alternatives. All the staff are lovely, they remember us when we go in and as you would hope, the whole team are very professional.

Professional and friendly
Staff is great and Dr. Marston always asks me and my boys if we have any issues, questions or concerns. Dr. Marston always recommends monitoring and letting the body do the work if the adult teeth are progressing well to replace the baby teeth rather than jumping into an invasive procedure.

"Both of my daughter's are very apprehensive about going to the dentist, however they were at ease with Dr. Marston as well as the entire staff at Marston Orthodontics. Every single person made my girls feel welcome, comfortable and calm. My youngest even said after x-rays, "Mom, I want to come here, the lady is so nice!" Dr. Marston explained all of my options, for both girls and made sure I didn't have any questions for him. He even answered all of my 7 year old questions! I highly recommend this office!"
