I have had three of my kids treated by Dr. Spilsbury and I agree he is the best in town. He only prescribes permanent solutions so your kids don't have to wear braces twice . He refuses to put on a set of braces too early which is unique; he makes sure their teeth are at the level they need to be before he does treatment. Most orthodontists tend to do what ever a parent demands.
I would highly recommend Dr. Spilsbury for getting the right treatment the first time. Check his education too, He graduated from the UCLA School of Orthodontics.
I would recommend him very highly
