Dr. Nass is patient, knowledgeable, and has a very acute understanding of different possible conditions. He plans for long term health, not just a rushed diagnosis. I feel completely comfortable trusting his expertise.

One the most caring amazing doctors i have ever met. takes care of my mom. a wonderful man

Dr Nass does not believe that some symptoms are not caused by a persons laziness or lack of willpower. I thought for sure I had sleep apena and Dr Nass told me it wasnt so even when my mom said I snored. He even thought I was being foolish for suggesting a CPAP and never even heard of the device as if I was telling a fabrication. I have suffered permanent brain damage because it wasnt treated right away. Dr Nass just thought I was staying up all night. Avoid this doctor he does not have your best interest in mind.

Doesnt accept any insurance!
