About Us

Positively impacting lives with convenient family orthodontics in Souderton, Perkasie, and Quakertown, PA.

Justin Silvestre, DMD

“Worry not, my child (or child at heart), we’re not here to do anything to you, we’re here to do it WITH you.”

Life brought Dr. Silvestre into dentistry, but his passion led him to orthodontics. Our board-certified orthodontist loves creating the ultimate smile (with both beauty and function in mind), helping our patients achieve better well-being.

One of Dr. Silvestre’s favorite parts of the job is working with our amazing community and the dedicated team at Orthodontic Specialists. He believes in always giving – whether transforming smiles in the office or contributing to our community outside of work.

In his free time, Dr. Silvestre stays busy with his wife, Candice, and four children, Eli, Sammy, David, and Lucy. In addition, he enjoys fishing, running, hiking, and going on adventures with his family.

His heroes are his parents. He gets his easygoing, “focus on what’s important” attitude from his mom and hard work and “always keep your head up” attitude from his dad.

Robert A. Azarik, DMD, MDS

“I’m fortunate to have been doing orthodontics for a long time, and I’ve seen almost everything. I’ll find a solution even if it’s not obvious.”

Dr. Azarik has always loved building things and still enjoys putting things together. From a young age, he was inspired to join the dental field by his own orthodontist, family members who were in the field, and his brother-in-law (they worked together for 20 years, and Dr. Azarik ran the practice after his brother-in-law’s retirement).

The best part of Dr. Azarik’s job is seeing the end result and the smile on the patient’s and parents’ faces. He feels very fortunate to be able to contribute to our community in a meaningful way.

In his free time, our orthodontist loves spending time with his wife of 40+ years and their two sons and daughter-in-law. He enjoys playing golf, traveling, and spending time at the beach or riding his bike in Maine.

A few fun facts? Dr. Azarik’s hero is his dad, who taught him so much and made him the man he is today. The best day of his life was when he became a parent for the first time. Being responsible for a little person was scary and the most exciting time for him and his wife.

Greg Gittleman, DMD, MS

“Each day, I'm excited to help patients unlock their full smile potential, knowing from personal experience that it can positively affect their self-esteem and oral health.”

Dr. Greg Gittleman is a proud native of Allentown, Pennsylvania, where his passion for dentistry and commitment to excellence began to take shape. He further honed his leadership skills and teamwork mentality as the captain of the cheerleading team at Penn State University during his undergraduate years.

Dedication to excellence is deeply ingrained in his orthodontic journey, shaped by both military service and specialized training. Dr. Gittleman believes that creating a welcoming, comfortable environment is paramount to successful orthodontic care. His strong sense of empathy and ability to connect with patients on a personal level fosters trust, making every patient feel heard and understood.

Dr. Gittleman currently resides in Pennsylvania with his wife, Rebecca, and three sons, Zachary, Tyler, and James. Beyond his dedication to orthodontics, he adds a delightful touch of humor to the office, contributing ‘dad jokes’ to create a cheerful and lively atmosphere for both his team and patients.

Review Stars
A+ staff, front desk to orthodontist. Professional doctor, yet relatable, humble, and connected to the community. I feel the type of staff you have says a lot about the boss. Dr. Silvestre has a great team working alongside him. I was impressed 18 months ago at my daughter’s consultation and thrilled with her gorgeous smile today.

Orthodontic Specialists is hands down the most amazing office we’ve ever stepped into! From the moment we walked in, we felt right at home. All the assistants are friendly and upbeat. Dr. Justin explains things so the kids can understand them, and takes the time to answer any questions the parents might have as well. He’s compassionate and knowledgeable. The entire office staff makes the whole experience smooth and effortless.

Review Stars
Dr. Justin and his staff are excellent to work with. So much so, half of my household is currently under orthodontic treatment with them! My daughter just had her braces removed yesterday. Prior to treatment, she had an underbite and was on the cusp of needing jaw surgery. Her treatment plan worked great. No more underbite, and we were able to avoid jaw surgery.
