The Team


Treatment Coordinator

Angela knows orthodontics! Not only has she been working with Dr. Newman since 2010, she is a mother of two children who underwent orthodontics, and was most recently an Invisalign patient. Angela understands the concerns that both parents and children may experience. She will tell you to fuggedaboutit and have a sit down to carefully explain you or your child’s orthodontic treatment. Not only will Angela help you decide what orthodontic treatment is best for you, she will also be sure to tell you the latest about her kids, and the “the best restaurant you gotta try!”


Financial Coordinator

From the day Julia walked through the door we immediately knew she was a great asset to our team. Sure she answers phones and makes appointments, but she also manages to make sure our waiting room remains pristine. All this while maintaining a smile. We thought she was just super happy until we discovered she was constantly laughing at her own jokes. Ask her to share a knock-knock joke, those are her favorite!


Scheduling Coordinator

Page is the newest addition to the Newman Orthodontics team and we couldn’t be happier. She takes great pride in keeping our schedule running as seamlessly as our treatment, efficiently, and on time. Rumor has it she once made a patient who was running late drop and give her 20.  Behind that tough woman exterior is a huge heart. Just show her a photo of your puppy dog and watch the warmth shine through.


Creative Director

Spencer strives to make sure our office is the most up to date on all social media and trends. If you are one of our amazing Instagram followers you are one of Spencer’s fans. He not only maintains our social media, he is also our “in house” photographer and can be seen secretly taking photos of our smiling patients. He strives to maintain a positive attitude and keep everyone smiling. Outside the office, Spencer’s a DJ and loves to make music in his free time.


Lead Orthodontic Assistant

Daisy enjoys working in our office, but she loves to dance. She has been known to spontaneously break out with some impressive moves. After narrowly missing acceptance to Juilliard, Daisy started her dental career at BOCES Technical School. Not only is she a talented orthodontic assistant, she also makes sure our clinical area is well stocked and running in tip top shape. Our patients always enjoy working with Daisy as she is always calm and works with grace, but mostly she has been known to share some of her moves.


Orthodontic Assistant

Jisselle has come a long way from when she entered the dental field by answering phones for a general dentist. Although she loves to talk, she discovered that working with patients was her true calling. She loves being an orthodontic assistant and prides herself in working with our most challenging patients. Jisselle knows how to make an impression, especially when it’s for a retainer. Jisselle was once rumored not to smile for five minutes straight, it turned out she was only sleeping.


Orthodontic Assistant

Yarmin started in our office as a records technician. Although she took some pretty awesome records, it wasn’t long before her talents began to shine through and we prompted her to be an orthodontic assistant. Not only is she bilingual and fluent in Spanish, she is rumored to have a strong understanding of Mandarin. Yarmin’s empathy and gentleness always makes our patients feel at ease. She has a strong interest in cosmetics and facial esthetics, and therefore, always looks her best!


Orthodontic Assistant

Kelsey always knew she had a passion for teeth when she found herself always staring at her own. She joined our practice hoping to gain some hands-on experience in the dental field and quickly fell in love with orthodontics. If she’s not in the office, you can catch her shopping till she drops. She still holds the record for the fastest iTero scan with a time of two minutes six seconds.


Orthodontic Assistant

Since joining our practice, Karla has become a big asset to our team. Other than her selfie taking skills, she takes pride in her record taking and intraoral scanning skills. She won’t rest until all of our instruments are sterilized, packed, and ready to use. When Karla is out of the office she loves to cook, so don’t forget to ask her about one of her newest recipes. They are so amazing!


Office Manager

Be careful, Taylor’s smile and enthusiasm is contagious, that is unless she is without her coffee. Taylor loves what she does, so much so, we never give her a day off. Taylor has recently become our office manager and we couldn’t be happier! Taylor strives to keep our office running smoothly and ensure our patients are always having the most positive experience. She is also always there to listen to any concerns you may have and help guide you through every step of your orthodontic treatment. Just like Clark Kent, Taylors signature accessory is her glasses. If you’re a super girl fan, just ask her to take them off and watch what happens.


Creative Director

Spencer strives to make sure our office is the most up to date on all social media and trends. If you are one of our amazing Instagram followers you are one of Spencer’s fans. He not only maintains our social media, he is also our “in house” photographer and can be seen secretly taking photos of our smiling patients.

The Office

Our Story

After graduating, Dr. Seth Newman entered “real world orthodontics” only quickly to realize there was a problem. The focus had become centered around the mechanics of orthodontics and lost sight of those we were there to serve. This frustrated Dr. Newman and he knew he could do it, as some would say, “more better”. In 2007 he opened the doors of Newman Orthodontics with a core value of value: “It’s not about us”. By putting patients first and investing in a first-class team, our vision has become an amazing practice. We love our patients (not in a creepy way) and we know our patients feel the same.

In 2014, Dr. Newman and his team were able to expand these philosophies by opening an office in Garden City. By merging the practices of Dr. Daniel Bythewood and Susan Tierney, they rebranded as Straight Set Orthodontics. Most recently, in 2019 open a new location in New Hyde Park by acquiring the office of Dr. Margaret Zadnik.

Our team of amazing doctors now also includes doctors Tyrun Ray, Tina An, and Himank Gupta. With the mission of providing the best orthodontic treatment in Nassau County, our doctors continually travel nationally and internationally to bring the worlds best treatment home to Long Island. Our team will never stop focusing on giving our patients a wonderful experience, it’s who we are…
