My visit was short.. I did not need to wait long at all. All the right questions were asked, in regards to my health.

Dr. Singer's office is so efficient from their pre-screening visit through their follow up after the procedure. I am having my 4th preventative screening procedure in the last 10 years and would trust no one else to do it other than Dr. Singer and his team. They are the best!

Dr Singer treated me with kindness and listened to me. He answered my questions and explained what my treatment plan would be. I feel like I’m in gd hands here. The office people, nurses are all nice, knowledgeable and you feel welcome when you come there. Thanks! 🙂
