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 Doctor Andres Gonzalez. 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…
