The mark consists of the letters "ESL", the word "office", and a stylized figure. The letters "ESL" on the right side of the mark are large, capitalized, and in medium green. Immediately below the letters "ESL" is the word "office" in smaller, bold, capitalized letters in black. The stylized figure on the left side of the mark is in medium green and is formed by a triangular-shaped figure with a straight-line side on the bottom and two convex sides rising to a point, an arrow with a thin shaft skewing to the right out of the base and joining an arrowhead, an arrowhead in the form of a triangle with a concave bottom side and two straight sides rising to a common point on the right side of the figure, a second shaft rising from the left side of the mark and attaching to the arrowhead at a point above and adjacent to the first shaft, and a small triangle at the top left corner of the mark with two sides of differing lengths forming a right angle to the top and left and a concave hypotenuse side. The small triangle, the arrowhead triangle, and the base triangle together form the appearance of a rectangle within which the figure is located. The mark is set against a white background.
