Our Coaches

Who We Are

Gary B. Cohen

Managing Partner – CO2 Partners, LLC

Gary is famous for asking; he wrote the book on it.  He probes his clients with the only kind of questions that can produce change: unexpected ones.  From the client’s answers,  this dedicated Minneapolis leadership coach offers not just insights but alternative courses of action.

“There always are several good roads to Rome,” he says.  “The key is to identify the one that best fits both your head and heart.” And he focuses on Rome–and not the possible curves in the road–for a simple reason: most obstacles are artificial, and the rest are in our heads.  “Clear your head,” he has said, “and the obstacles disappear.” This may explain why Gary’s clients call him “eccentric in exactly the right way.”  He knows that unusual success comes from unusual approaches, and–as Gary often has said, “I never have met a client who wanted to be ordinary.”

Mark Feil

Executive Coach

Mark has spent his entire career building winning organizations in technology.  His background includes senior leadership positions within F500’s and small private companies; he has also started his own technology solutions practice.  In each of those settings, Mark has exceeded corporate financial goals, grown revenue, and contained expenses.  Whether working for a large technology company, or a small start-up, he has never failed to be recognized as number 1 among his peers.

Mark’s approach is to use a combination of mathematical and statistical analysis, sound business practices, psychology of selling and buying, and creative technology solutions.  By combining these disciplines, new ways of approaching problems create environments that allow for accelerated productivity.  The approach can be summed up this way:  “I change the game, write rules for the new game, then beat the competition at a game they didn’t know they were playing, using rules they didn’t know existed.”

As Vice President of Sales at telecommunications providers Global Crossing and Broadwing, Mark was recognized as the highest producing sales leader in the world, landing numerous multi-million dollar global network contracts.  Clients included Ford Motor Company, 3M, Daimler Chrysler, and ACI Telecentrics.   During his tenure, Mark was awarded Chairman’s Club, President’s Club, and multiple Quarterly Achiever’s Circle awards.

In 2003, Mark co-founded WanConnex LLC, a consulting firm specializing in technology, sales, and marketing.  A self-funded venture, Mark and his partner achieved profitability within the first year; and double digit CAGR revenue growth for 5 subsequent years.  Upon selling WanConnex in 2009, Mark became General Manager at XO.  Within 15 months, he turned a flat revenue market into the highest growth market for 2 years, running 19% and 22% sequential revenue expansion.   He then led the Data Center and Cloud Technology business, a $100M revenue stream, once again creating a team that over-achieved and finished 2014 at 135% to plan.

Mark joined CO2 in January of 2015 and brings a unique approach to sales, marketing, and technology.  As someone that has actually been in the trenches, lying awake thinking about hitting quota, he brings a very pragmatic, focused approach based on real life, real world experience.  Whether it’s using funnel management tools, sales training, or performance improvement plans, or creating winning sales teams, Mark’s methods have proven to out-sell, out-grow, and out-motivate his competition.

Mark has a BA in Mathematics (emphasis on Probability and Statistics) from the University of Minnesota, Twin Cities.
