A Message From Our Founder

Marcia Gauger

Thank you for considering Impact Sales for your performance development needs.


For nearly three decades, we have worked with thousands of professionals to reach and exceed the performance expectations of their industries, organizations, clients and most importantly – themselves.


Early in my career, suitcase in hand, I developed hundreds of custom training programs and blended-learning solutions and facilitated thousands of sessions.


Our business was founded on offering custom-designed sales and leadership solutions for our clients and in the early days these were primarily delivered via live training or through elements of “train the trainer.”


Blended learning has always been the cornerstone of our methodology. Technology continues to shape our solutions to include more online collaboration and delivery methods, asynchronous and synchronous e-learning solutions, real time coaching and learning support, assessment and measurement. In the 2000’s we introduced the DVR Learning partnership to recruit talent to transform many of our face-to-face solutions to online offerings.


The programs were embraced beyond our expectations. Success came in part because of our continual improvement of the programs. We carefully researched and documented behaviors of top performers who attended our sessions, paying attention to what really works in terms of developing performance excellence. It’s paid off. The initial research into characteristics of top performing sales and leadership behaviors is now the foundation for the extensive library of customized and proprietary training programs we offer.


We have embraced the waves of change from the technological revolution to economic ebbs. Our commitment remains steadfast to always provide solutions to best meet the needs of the modern learner and learning organization.


I reflect on what we’ve accomplished and our innovation, often adopting early thinking in modern learning technologies. We can only accomplish this by astutely paying attention to industry trends and our clients’ businesses. I am proud that through this dedication we have been a constant in the performance development field.


For we know the one constant in business today is, business results are driven by human performance.


I coined the name Impact Sales in the early 90s to reflect our commitment to making an impact on both business and human performance results. After all, training is only training unless it makes an impact!


Please take a moment to explore our offerings and then let’s develop the best program to meet your human performance needs. We would be delighted to partner with you to deliver performance excellence.
