Alexander Gruenstein, DDS

Alexander Gruenstein, DDS brings a rare combination of advanced clinical training, broad hospital experience, and a genuinely patient centered approach to Emerald Dentistry. Raised locally in New Rochelle, NY, Dr. Gruenstein has always felt a strong connection to the communities he now serves. That local perspective shapes how he practices dentistry today, with care that is personal, respectful, and grounded in long term relationships rather than quick fixes.

Dr. Gruenstein earned his undergraduate degree from the University of Rochester in 2013 before completing his dental education at Columbia University College of Dental Medicine. Following dental school, he pursued rigorous hospital based training through a General Practice Residency at Newark Beth Israel Medical Center. He then went on to complete a Chief Resident year, PGY2, at Saint Barnabas Hospital in the Bronx, where he treated a wide range of complex dental and medical cases and further refined his clinical judgment and leadership skills.

This extensive hospital background allows Dr. Gruenstein to confidently manage everything from routine preventive care to advanced restorative and implant dentistry. He is a Fellow of the International Congress of Oral Implantology and remains actively involved in continuing education to stay current with evolving techniques, materials, and technologies. His professional affiliations include the International Congress of Oral Implantology, the Academy of General Dentistry, and the American Dental Association.

At the core of Dr. Gruenstein’s philosophy is a commitment to honesty and patient education. He believes patients deserve clear explanations, realistic options, and the time to make informed decisions without pressure. Treatment is never rushed or pushed. Instead, each recommendation is carefully tailored to the patient’s needs, goals, and comfort level.

Patients often describe Dr. Gruenstein as calm, thorough, and approachable. He takes pride in building trust through thoughtful communication and meticulous care, whether he is performing a routine exam, restoring damaged teeth, or planning a complex implant case. His focus is always on delivering high quality results that support long term oral health and confidence.

Through Emerald Dentistry, Dr. Gruenstein has created a practice environment that reflects his values. The office combines modern technology, premium materials, and a warm, compassionate atmosphere where patients feel heard and respected. His goal is simple but meaningful: to provide dentistry he would want for his own family, delivered with integrity and consistency.
