Dr. Nasar has performed knee replacement on both of my knees, the first one was 8 years ago. The first time was so successful there was no way I would have any other doctor when I had my other knee done 3 months ago! Not only is he an expert in surgery but he also takes great care of his patients. He takes the time to listen to you and talks about options available.

For the seventh graders, Mr. Dowling, science teacher, brought in a full-size skeleton and Dr. Nasar reviewed the names of the bones on the skeleton. He also discussed treatment of fractures with casting, external fixation and open reduction, and internal fixation. He then narrated a surgical video demonstrating total knee replacement.

At the conclusion of the event, Dr. Ruth Katz, Head of School, thanked Dr. Nasar for his long-standing commitment to Hillel Yeshiva and his attendance at health week for multiple consecutive years.
