    Dr Sass is thorough, efficient, a careful listener, knowledgeable, a trusted source of prudent recommendations and has a personable way of speaking with me that is a perfect fit for what I want in my doctor. I suspect that all doctors care about the welfare of their patients, at least they should; in Dr Sass' case, it's evident from the beginning to the close of the appointment.
