We loved Dr Singer but the office is poorly managed. Our first appointment had us wait an hour and a half and it took 3 hours to do an intake which was $700 and 4.5 hours later. Another appointment had to be rescheduled after waiting an hour. We asked for my son’s medical records multiple times and the front office never sent them. We needed a super bill to submit to insurance and I had to call/ email several times over weeks to get the office to send it. I almost had to just go back into the office.
However, Dr Singer did help so he is amazing.
I wish he had an admin to help.

Reviews
Dr. Singer is the best. Knowledgeable and a great conversationalist, he always gets to the root of your problem and proposes the most efficient solution. I know my health is in good hands whenever I visit.
Dr. Singer has been our family doctor since 2013. Members of his office staff are always very helpful. I have full faith in Dr. Singer and all of his protocals. I can not say enough good things about him and his services.
