Hello ALL!

Just a note to say we look forward to opening as soon as we are safely able to do so. We are awaiting the new normal. The challenge of our return, will be measured with safety to all being our main priority. Changes are underway and we will update as we progress. Telle dentistry is under construction. Testing is one of the things to get resolution on. Emergency phone number is there if needed. For doctor Seiger you may call (908) 642-5333.

In the meantime for the homebound, here are some videos of a busy day at the Boston Aquarium.

Stay Safe,
Dr. O, Mayra, Carol, Doris
