Our Services
Early Orthodontic Treatment & Expanders
At Rafati Orthodontics, the early treatment we provide involves diagnosing and addressing orthodontic issues in children while they are still growing and developing.
Adult Orthodontic Treatment
A radiant smile knows no age limits. Adult orthodontic treatment has emerged as a transformative solution that breaks age barriers, offering a chance to achieve the smile you’ve always wanted.
Surgical Orthodontic Treatment
A captivating smile is a window to confidence and self-assuredness. As children grow and develop, their oral health is crucial to their overall well-being.
Invisalign Clear Aligners
A captivating smile is a reflection of confidence and well-being. Sometimes, though, achieving that radiant smile involves more than just braces or aligners.
Flexible & Affordable Payments
We have affordable treatment options including interest-free payments within two years.

Monse Fernandez17 March 2026I’ve been a patient at Dr. Sima Rafati’s office for the past four years, and I truly couldn’t be happier with my experience. From the very beginning, Dr. Rafati and her team have been incredibly professional, welcoming, and attentive. They always took the time to explain each step of my treatment and made me feel comfortable and confident throughout the entire process. Now that my treatment is complete, I can honestly say I have a beautiful smile that I’m so proud of. The results exceeded my expectations, and I’m beyond grateful for the care and precision Dr. Rafati put into my case. If you’re looking for an orthodontist who is skilled, patient, and genuinely cares about her patients’ outcomes, I highly recommend Dr. Sima Rafati. Thank you for giving me a smile I love!Posted on Google
