“I love this Dentist! He’s thorough, discusses options prior to any dental work, fantastic results and I fall asleep in the chair EVERY TIME!”




He is originally from Ukraine, and immigrated to the United States at a young age with his brother and parents. He and his family eventually settled in Baltimore, Maryland where he attended college at University of Maryland, College Park and attained a B.S. Degree in Psychology with a focus on the pre-dental track. He then moved once more to attend dental school at New York University – College of Dentistry in Manhattan, NY.

After comprehensive study of general dentistry principles and techniques, he continued his dental education further and completed an in-depth General Dentistry Residency in Woodhull Hospital in Brooklyn, NY. During this post-doctorate training he was able to treat the most severe of oral conditions and bring his patients back to great oral health and aesthetics.

Since his completion of residency, Dr. Kroner has worked in many dental practices throughout New York City serving nearly all of its boroughs. Through all of this practice and experience, he had not quite found a dental practice that delivers treatment at his unwavering standard of care, leading him to start his own dental practice.

He believes that dental treatment is a team effort between himself and our patients, which requires clear communication and understanding of options, procedures and outcomes. He is a firm believer in transparency and a patient-specific approach. We are all a little bit different with different needs. 🙂
