Our Experience Makes Your Experience Better

At Mastaj Orthodontics we’ve built our reputation one smile at a time. That’s what we’ve done for over 30 years and that means you can count on a patient experience that makes being in treatment almost as great as the day your new smile is complete.

The team you choose to create your best smile makes a big difference no matter what type of orthodontic treatment you choose, but this is especially true when you’re interested in Invisalign® Treatment. While many dentists offer Invisalign, you should always trust your orthodontic treatment to an orthodontic specialist and when it comes to Invisalign treatment, there’s no better choice than Dr. Mastaj. 



Dr. LynAnn Mastaj is an orthodontic specialist. After attending Wheaton College for her Bachelor’s Degree, she received her Dental Degree from the University of Pennsylvania and her Orthodontic Specialty Degree from Albert Einstein Medical Center.

She has been creating beautiful smiles for Philadelphia area residents of all ages since 1988 and is one of the areas leading providers and most respected doctors – and that’s all-important, but what really sets Dr. Mastaj apart is the way she approaches orthodontics. She understands that the way she treats you is just as important as the way she treats your teeth.

“Having a beautiful, healthy smile just seems to bring out the best in everyone and I love that. I get to be a catalyst for that kind of positive change.”     – Dr. Mastaj
