Care Philosophy

This content was provided by Dr. Nassberg "My practice is centered on high quality care and patient satisfaction.

Waiting times are short and appointments are long enough to allow good interaction. Appointments are available without long delays.

There are no mid-level practitioners- I do all patient care.

There is no voicemail jail- a human will answer the telephone during office hours.

I order only the tests that I feel are necessary and use the best available medications.  I Iry to hear the concerns of my patients and am happy to answer questions about their health, as well as the tests and treatments I prescribe for them.  If I have to refer patients to other doctors, I try to choose someone I would pick for myself.

Treatment is adapted to the patient's lifestyle and preferences as much as possible and goals are set to be best for every unique patient.

My goal is to treat patients as I would want to be treated myself."

Jackson, NJ |
Just called this office. He accepts NO commercial insurance. I was given NO information about any of the visit fees. I was repeatedly told by the woman who answered the phone, the fee depends on your condition. So expect to go in blind and be surprised by whatever the charges may be. I was also told that his specialty is endocrinology so don't even bother if you are searching for an internist.

This was my first visit, and right from the receptionist to Dr Nassberg himself, the treatment was first-rate. He spent quite a bit of time with me, made me feel comfortable and I left there highly confident of his capabilities.
