Our Amenities
At Rock Hill Orthodontics, we want our patient’s dental visits to be as pleasant as they are productive. Our comfortable lobby offers complimentary refreshments that patients are free to enjoy before or after their treatments. Each of our private treatment rooms also contains TVs with Netflix and Hulu access to help patients relax and tune out their surroundings while we work on their smiles. If there’s anything else we can do to make your family’s visits better, please just let us know!
Advanced Digital Technology
Our office uses a combination of panoramic X-rays, intraoral cameras, and smile preview software to design our patient’s custom treatment plans and give them a sneak preview of what their smiles will look like. We also utilize digital scanners and 3D printing to create highly precise impressions of our patient’s teeth—no biting into goopy dental putty required! Our team invests in advanced technology and the newest orthodontic practices to keep our care cutting-edge and highly efficient.

Meet Dr. Mitchell Siegelman
Dr. Mitchell Siegelman is an orthodontist dedicated to creating healthy, confident smiles through personalized, modern orthodontic care.
A New Jersey native, Dr. Siegelman grew up in Edison and is proud to provide orthodontic care to patients and families throughout the Central and South Jersey communities.
Dr. Siegelman earned his BA in Mathematics from Queens College before receiving his Doctor of Dental Surgery degree from Touro College of Dental Medicine. He then remained at Touro to complete his specialty training in Orthodontics and Dentofacial Orthopedics.
His interest in orthodontics began early in his dental training. Dr. Siegelman served as President of the Orthodontics Club, and received the American Association of Orthodontists Award for Excellence in Orthodontics. During his orthodontic residency, he was also awarded a research grant from the Northeastern Society of Orthodontists for his work developing and advancing orthodontic treatment technology.
Dr. Siegelman has extensive experience treating children, teenagers, and adults with traditional metal braces, ceramic braces, and clear aligners. He believes successful orthodontic treatment begins with understanding each patient’s individual goals and developing a treatment plan tailored to their needs. He incorporates modern digital technology, including intraoral scanning and 3D treatment planning, to make orthodontic care as precise and efficient as possible.
For Dr. Siegelman, orthodontics is about more than straight teeth. His goal is to create a healthy, functional bite and a smile that patients can feel confident about for years to come. He especially enjoys building relationships with patients and their families throughout treatment and seeing the transformation that takes place from the first consultation to the final result.
Outside of the office, Dr. Siegelman enjoys spending time and traveling with his wife, Shoshana, their daughter, Kai, and their two dogs, Terri and Sunday. He is an avid golfer in the summer, snowboarder in the winter, and local foodie year-round. Dr. Siegelman currently resides in North Brunswick and looks forward to continuing to serve and be a part of the New Jersey community he has always called home.

Cat
Hi, my name’s Cathryn, but most people call me Cat. I am an RDA and the Clinical Manager of Rock Hill Orthodontics. I’ve been a dental assistant for over 10 years, with 8 years of experience in pediatric dentistry before moving into orthodontics. I love getting to know our patients, watching their confidence grow, and making their visits a little more fun. Outside of the office, you can usually find me staying active, spending time with my husband and our mini Bernedoodle, Stella, or planning my next adventure. I’m a big Philadelphia sports fan, a Taylor Swift enthusiast, and rarely seen without an iced coffee in hand. I love a good laugh, making memories with my favorite people, and finding a reason to celebrate the little things in life!

I even used to make wedding cakes, which allowed me to turn my creativity and attention to detail into something special for others. Whether I’m helping create a beautiful smile or a beautiful cake, I love being part of something that brings people joy!
