I have no idea what others charge.
Two children and one adult in our family use Dr. Rubin. His staff always are helpful and pleasant. Dr. Rubin has been great with the kids and, thus far, the results are as expected. He takes a conservative, reasoned approach, knows the latest technology but only applies what is right for a particular patient and has a proven track record. His manner with patients is excellent and visits to the orthodontist have never been a problem with the kids. His referrals to other specialists, when needed, have been first rate. If something breaks and you need to be seen on short notice, they fit you in.
Most orthodontic patients have to make many visits so, if Dr. Rubin's location is accessible, he's the one to use. (Validated parking is a bonus, with a Starbucks and Einstein's down the street for parents who have to wait for their kids.) The fees are established up-front, then paid in monthly increments so there are no surprises, no matter how long treatment ends up taking.
Hint: they are in this office three days per week and many kids have extra-curricular activities with schedules for a whole semester so make all your appointments for a whole semester ahead. You can always change them.
