Dr. Marc Lemchen

Orthodontist in NYC with 50+ Years Experience

Dr. Marc Lemchen has spent five decades providing relationship-driven orthodontic care to New York families — and shaping the specialty itself. A true master orthodontist, Manhattan has been home to his pioneering work in digital orthodontics since 1974. Raised in Maplewood, New Jersey, he studied at Lafayette College, earned his dental degree at Tufts University School of Dental Medicine, and completed advanced orthodontic training at Columbia University. Known for his calm demeanor and precise eye, he remains the doctor other doctors consult.

Dr. Marc Lemchen’s career in orthodontics reflects a lifelong commitment to both intellectual rigor and meaningful human connection. Raised in Maplewood, New Jersey, he pursued his undergraduate studies at Lafayette College before earning his dental degree at Tufts University School of Dental Medicine. He continued his advanced training in orthodontics at Columbia University, building a foundation rooted in both academic excellence and clinical precision.

With more than five decades of experience in orthodontics, Dr. Lemchen has developed a reputation for thoughtful diagnosis, careful planning, and a deep respect for the individuality of each patient. His work is guided by a belief that orthodontic care is not simply about achieving a result, but about building lasting relationships and creating an experience that feels supportive from start to finish. He values the balance between technical expertise and human understanding—recognizing that both are essential to delivering exceptional care.

At the core of Dr. Lemchen’s philosophy is communication. He approaches each case with a non-defensive mindset, taking time to listen carefully, ask thoughtful questions, and fully understand each patient’s expectations. From there, he provides clear, detailed explanations of treatment options, ensuring patients and families feel informed and empowered in their decisions. He believes that trust is built through transparency—and that clarity is one of the most important aspects of care.

Dr. Lemchen is particularly attentive to the needs of children and families, recognizing that orthodontic visits can sometimes feel unfamiliar or overwhelming. His approach is grounded in patience, warmth, and respect—never forcing treatment, but instead guiding each child at a pace that feels comfortable and appropriate. By creating an environment that prioritizes understanding and reassurance, he helps patients feel at ease throughout their care.

Throughout his career, Dr. Lemchen has embraced innovation and change, maintaining a strong interest in technology and its role in improving orthodontic outcomes. In addition to his clinical work, he has founded several software and technology companies, reflecting a forward-thinking mindset that continues to shape the practice. His philosophy is simple: progress requires openness to change, and excellence comes from continually refining both technique and perspective.

Outside of the practice, Dr. Lemchen enjoys spending time with his wife, Debbie, and their family. He takes great pride in seeing his son, Dr. Andrew Lemchen, continue the tradition of orthodontic care in New York City. Together, they share a commitment to delivering thoughtful, high-quality treatment to the families they serve. In his personal time, Dr. Lemchen enjoys exploring new technology, collecting unique automobiles, and spending time at his country home, where he enjoys boating and fishing.
