That’s why we go above and beyond for you, exceeding the American Dental Association (ADA) and OSHA recommended standards for a clean and safe practice. We have a dedicated area with state-of-the-art sterilization technology, where every instrument is wrapped and disinfected before your visit. We also sanitize each room between patients and perform weekly spore testing with a third party infection control center. We worry about the cleanliness of our office so you’ll never have to!

Steven J. Rosenstein, DMD

I was born in Albany, NY, in 1950. I was blessed with a warm and loving family life in my youth and it certainly impacted on my adult years. I attended Colgate University before moving on to the University of Pennsylvania School of Dental Medicine. After completing a General Practice Residency in the United States Public Health Service, I returned to Philadelphia to begin my private practice career. After 21 years I decided to move to Florida and have been practicing here since 1998.

My accomplishments in Dentistry are a source of pride and fulfillment for me but my greatest joys come from my wife of 40 years and my wonderful children. Both our children developed our love of learning and have achieved at a very high level academically.

I am committed to helping my patients achieved the maximum level of oral health through carefully listening to their desires, concerns and any fears that may be present. Together we devote significant time to understanding the current status of your dental health and planning for a more comfortable and predictable future. I believe it is best to always make quality the constant and time the variable in achieving your goals.

Outside of dentistry and time with my family I love to play golf, read and enjoy music of all kinds. My wife and I enjoy art festivals, movies, live plays and the ballet. We are also very committed to our three dogs, Sasha and Emma are Soft Coated Wheaton Terriers and Hugse is an Italian Greyhound.
