"Selling Energy is dynamic, continually improving, current, and a step ahead into the future."

First, you introduced me to energy efficiency in buildings, residential housing, commercial building, and construction in general. You educated me accordingly to show why energy efficiency is important as a cost-saving and profitable for me and my family as a private individual and for all categories of businesses. You taught, showed, and proved that efficient heating, cooling, lighting equipment, and systems when efficient improve the quality of life for people, the nation, and the environment. You show the technical and academic foundations of energy efficiency to convince people to buy efficient energy. You showed how people and businesses make the decision that drives all categories of business life. Selling Energy is dynamic, continually improving, current, and a step ahead into the future. I love quotes of wisdom, book and article references. It is great to see a winning team in action continually giving.

"He digs into how your enthusiasm, presentation, and habits impact your accomplishments... "

Mark's program addresses every aspect of being a successful sales professional, which really gets at being successful in life and the pursuit of goals. He digs into how your enthusiasm, presentation, and habits impact your accomplishments, as well as how those you encounter -- not just prospects, but everyone you meet -- can make a huge difference in your achievements. This was the best time spent in training, out of the multiple degrees and hundreds of hours of CEUs, that I have ever done. Well worth the full cost, and then some!

Mark is a fire hose of information that brings value to our teams. I sent all of my sales team through the training because it helped set the foundation of proper sales techniques in an industry that is necessary and yet undervalued by the customer so we need to make sure we are at the highest level of educating and sharing our expertise and capabilities.

Mary Rose Kaczorowski

Mark is one of (if not the only) person out there doing effective sales training for the utility industries. He pulls from his own experiences as well as key points from other resources. I have yet to find another resource that his team researches for vertical markets like his segment guides.

Joe Cantwell
Product Sales & Marketing Manager at Johnson Controls
The training - topics covered, resources, and quite frankly ongoing support and enthusiasm - is a breath of fresh air in the industry. Especially for professionals who may not have a great sales manager, or are forced to sit through laborious and dreadful sales meetings. Mark is a great leader - inspiring to take meaningful actions by the sales professional, propelling their career to new heights through the correct way to make sales!

Jason Mulholland

I am quite familiar with Mark's trainings. In April and May I participated in the Selling Energy Series on Selling in an Economic Downturn Webinar Series...the course recently helped me save a project that I had proposed before the pandemic hit that was facing a buying freeze objection on consulting projects from my client that I was able to overcome. I am also working on improving in asking my current customers for referrals. Very helpful webinar series indeed.
