About Mark Clark

Mark helps businesses figure out what they actually need before any development starts. He leads discovery conversations, explains options in plain terms and stays involved after the sale, which clients consistently value. Mark came to eXcelisys from project management, wireless technology and business solution sales in both the public and private sectors, rather than a traditional programming path. He founded and ran his own business-to-business wireless sales company, a Nextel Communications dealership, so he could work with clients without pressure and on their timetable. He has solved communications problems for federal, state and local government agencies and for private businesses of all sizes, and has built a regional reputation for honesty and integrity. Outside work, Mark and his wife travel to places off the beaten track, especially ones with turquoise water and white sand.
