This is based on one visit, so take it for what you will.... I found Dr. Gruss to be extremely professional, capable and nice. She was a good listener, diagnosed my condition quickly, and there was only a minimal wait after I arrived at her office. (The wait to schedule an initial appointment was far too long, but it's like that everywhere. Not sure who to blame for that. Health insurance companies?) She's clearly intelligent and very good at what she's doing. I don't really understand the negative reviews except to note that she isn't gushy or fake hyper friendly. Thank goodness!
