Patient Reviews (3)
in Huntington, NY |
I had severe pain after my implant and finally it was taken out by another surgeon, 3 weeks later. Over all the process was smooth, how ever the billing was an issue and they wouldn't work with my insurance even though I call my insurance and confirmed that it was covered. I was not happy that they wouldn't return my money. I am very unhappy and extremely disappointed with the treatment. Everyone seems to have a very short fuse when you ask questions.

i have had several procedures performed by dr. diana, including bone and tissue grafting. they all went well, with no post operative issues.

I had a wonderful experience with Dr. Diana and his staff. They were always friendly and helpful. Dr. Diana laid out a plan for my long-term care and was very good at explaining all aspects of the plan and possible treatment options.
