Your trust is our top concern.

We strive to keep reviews honest, trustworthy, and fair.

Doctors can not pay for good reviews, nor can they pay to have negative reviews removed.

We monitor all reviews to ensure they comply with our guidelines and don’t include personal information, profanity, libel, defamation, harassment, obscenity or fraud.

Any reviews that are deemed fraudulent or violate our guidelines will be removed immediately.

All reviews are confirmed and audited before publication, and community members have the ability to flag inappropriate content for further review by our team.

Did extreme surgery that was NOT necessary.
Dr. Greenberg performed a surgery on me that was a disaster. Each time I went back for a post-surgery follow up he was non-communicative and kept requesting more time. I was left in worse shape than when I came in and was not covered by my dental insurance for the procedure performed. This went on for a total of over 6 months. Luckily, I went for a second opinion and found a Periodontist that knew what he was doing and was able to remedy my issue. Don’t WASTE your time or money at Dr. Greenberg’s office. It cost me over $1000, pain and suffering, loss of self esteem when trying to hide my teeth when smiling and loss of time at work.

I have been a patient of Dr. Greenberg's for over 25 years and have always been satisfied with the course of action he has taken through many surgeries and implants. He works very closely with my prosthodontist to ensure the best course of treatment from all perspectives. Additionally, his assistants and office staff are professional and friendly.

Dr Greenberg is really great both skill wise and personality wise. I’ve had gum surgery and bone grafting here and now come for regular periodontal cleanings which has kept my gums healthy. Dr Greenberg is just the nicest guy too, and his entire staff is as well. I’m really happy I was recommended to this practice several years ago.

Dr. Greenberg has been my periodontist for over ten years. He has always given me sound advice. He is thorough and skilled in his work. My three main procedures with him have all been a big success. He knows his field and keeps you informed along the way. I highly recommend him.
