About Your Dentist

Laurence Stein, DDS

Dr. Laurence Stein is a highly skilled and well trained dentist. Meticulous in his practice, he passionately pursues continuous learning to give his patients the highest quality of care and access to innovations in dentistry. While serious about the practice of dentistry, Dr. Stein is kind, caring and quick with a funny story or comeback. When Im working I am quiet and serious but when I stop I will tell you a joke! His easy manner and delightful humor combined with his impressive credentials put even the most anxious patient at ease.

"I am painless and take my time. I pay attention to changes in the industry, techniques and materials so that I can choose the best treatment modalities for my patients needs. You have to sort out the new but untested from new products that not only work but have good long term potential."

Dr. Stein graduated in the top 10% of his class at Emory University School of Dentistry and was inducted into Omicron Kappa Upsilon (OKU) National Dental Honorary Society. Immediately following graduation he did a one year General Residency at Mt. Sinai Hospital of Cleveland where his training included dentistry, surgery, emergency medicine, general anesthesia, advanced life support and head, neck and dental trauma. Dr. Stein has participated in everything from chipped teeth to gunshot wounds, cardiac arrest and major surgery. He has also completed many hours of training in implant and cosmetic dentistry and occlusion.

An avid spear fisherman and a certified dive master, Dr. Stein has integrated his hobby with his career. He once rescued a diver 80 feet underwater and has published articles for the Diver's Alert Network, part of Duke University's School of Medicine / Hyperbaric Medicine and is the dental consultant for Dive Medicine Online.

Married for 30 years, Dr. Stein and his wife have a married 27 year old daughter who he describes as "one of the smartest people I have ever met, and cannot believe that she even shares some of my genes" and an equally talented 24 year old son with an optician's degree headed to Optometry school.

When not in the office or spending time with family Dr. Stein can be found 10 miles out to sea and 100 feet down. Whether on land or sea, Dr. Stein most enjoys helping people and getting a great end result.

Roy Greenberg, DDS

With greater than 30 years of experience, Dr. Greenberg has earned respect from patients and colleagues as a practitioner and leader in advanced cosmetic dentistry. Dr. Greenberg has a long list of accomplishments but what patients most remember is his gentle, caring manner.

"When I give a patient a mirror at the end of a case, it makes my whole career choice worthwhile."

Dr. Greenberg has all the latest technology at his fingertips but believes his most important asset is how he treats his patients. His parents advised him to treat others as you want to be treated and this has been the cornerstone of his life. Before he gets intimate with a patient's mouth, he gets to know them as a person. "It's very important to me to build a relationship with my patients before I treat them. I want to know how many kids they have, what their interests are and what's going on in their life." Dr. Greenberg's top priority is never hurt a patient. "We don't believe in telling our patients that it's only going to hurt for a moment. Our whole team is committed to a pain free, pleasant experience for the patient."

A people person who has always been gifted with his hands, Dr. Greenberg is passionately living his dream. He went to medical school for a year but decided that was not the right path for him. With a desire to remain in healthcare, he found his true calling in dentistry, and more specifically in smile transformations.

"Transforming someone's smile is the most tangible thing I can do for a person. If it held them back in some way or made them insecure, you change their life. If I did nothing else but smile makeovers all day long, I would be very happy."

His impressive list of accomplishments and memberships include:

  • Graduate of State University of New York at Stony Brook
  • Graduate of Virginia Commonwealth University - School of Dentistry
  • American Dental Association
  • Delegate of Florida Dental Association
  • Secretary of South Florida Dental Association
  • Past President of South Dade Dental Society
  • International Congress of Oral Implantology

Music, movies and basketball are just a few of Dr. Greenberg's favorite things. He owns a baby grand piano and played keyboard in a rock band years ago. The group gets together annually to rock out to music of the 60s. An avid movie buff, he has a collection of more than 300 movies including his all time favorite, "Titanic." He loves to travel but one of his favorite places is South Florida. Great people, fun, sun, fine dining and great music are all elements that make Dr. Greenberg glad to call it home.
