With locations in Philadelphia, PA and Hatboro, PA, Orthodontics Limited provides orthodontic treatment in a relaxed, stress-free atmosphere and specializes in Invisalign, Invisalign for Teens, Braces, and Accelerated Orthodontics.

When they are not providing excellent care for patients like you, Drs. Gemmi and Middleberg teach at Albert Einstein Medical Center, sharing their knowledge by educating future orthodontists.

Most of their staff have been with them for over 15 years, so you will see the same welcoming faces at each appointment.

Whether you are a parent of a teen looking for braces, an adult looking to straighten your teeth, a an active 20-something curious about Invisalign clear braces, or simply someone who is looking for the best orthodontist in Philadelphia, Dr. Gemmi and Dr. Middleberg at Orthodontics Limited are orthodontists committed to making a true difference in your smile. They will make the perfect orthodontic recommendation for you and your lifestyle.
