About Plus Sign

The idea for Plus Sign came to be when it’s founder, David Olshever, began helping a friend who opened a new sign business. David was willing to do whatever was asked.  Over time, he found the most pressing need was lead nurturing and consistent follow-up on proposals and quotes. 

With over 20 years of corporate client services experience, David was well suited to help his friend and take on a sales support role.  In his prior life in the financial services industry, he was responsible for client relationships for hundreds of clients of all sizes.  


David launched Plus Sign with the goal to help other sign businesses maximize opportunities and eliminate the “black hole” so common in today’s face-paced business environment. Let David and Plus Sign help you, as he helped his friend increase sales and gain time to focus on day-to-day business priorities.
