Mark Dorn,
Founder of Impact Sales Group
Mark Dorn has over 40 years of successful sales and client development experience, working with management consulting and technology services. He has worked with a wide array of companies ranging from startups to the Fortune 100.
Starting with Wallace Computer Services in 1980, Mark has held a number of sales leadership and management positions with companies such as Digital Equipment Corporation, Paradyne, XcelleNet, The Giga Information Group, The Concours Group, The Hackett Group, PwC, The Association for Supply Chain Management, and Utopia.
During his career, Mark worked with 5 startup companies to successfully develop their “greenfield” territories by creating the strategy, team, sales process, value proposition, and target account plans to drive significant growth in clients, revenue, and profitability. In 2005, Mark started The Impact Sales Group, providing an executive relationship-based strategic sales approach that was the key to their successful 7 year run. This approach helped Mark achieve “trusted advisor” status with many senior executives in corporations across the country. As a result of his previous track record of success - Mark decided to restart The Impact Sales Group in 2021 to once again help clients grow their consulting and technology services companies on a contract basis.
Mark Dorn specializes in relationship and client development with CEO, COO, CFO, CIO, CHRO, and CSCO-level executives in Fortune 500 Corporations across the US and Europe. He looks forward to helping you develop your strategic long-term clients to close six and seven figure consulting engagements and achieve your growth goals.
