The mark consists of the stylized words "HILL" and "MEDICAL" set below a symbol. The symbol includes in its center a caduceus (a staff with two serpents entwined around it and wings at the top). In the bottom of the background, there are three stylized mountains with snow-capped peaks. In the upper two-thirds of the background are horizontal lines, with elliptical clearings around the caduceus. The entire symbol, excluding the words, is enclosed within a thick circular border.
Color is not claimed as a feature of the mark.
