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.” He focuses on the destination–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 believes, “and the obstacles disappear.” This may explain why Gary’s clients call him “eccentric in exactly the right way.” Gary has yet to meet a client who wants to be ordinary, and he helps them enjoy unusual success by employing unusual approaches.

Shana Finnegan

Shana Finnegan is known for guiding and engaging established and emerging leaders through an inspiring process of resetting their vision for personal and professional success, realigning their growth curve to achieve the vision, and refreshing beliefs and expectations that empower healthy behaviors and habits. While each coaching engagement is unique, there is one common outcome for all: experiencing joy and fulfillment in the process of growth in both work and life.

Shana’s approach to coaching is rooted in a belief that even the most accomplished leaders benefit from elevating their vision, levelling the ruts in the road, and expanding limiting beliefs and behaviors.

With more than two decades leading and transforming successful companies, Shana can relate to the challenges of C-level leaders. She believes that real growth – the kind that elevates people and accelerates personal and business growth – happens when we are willing to unravel and disrupt ineffective beliefs and habits, embrace curiosity and new ways of thinking, push perceived boundaries and limits, and finish what we start.

As COO and leader of several technology businesses, Shana has deep experience in business and leadership change initiatives and bringing them across the finish line successfully. Her passion is assessing, recommending, and implementing enterprise-wide initiatives that position an organization for profitable growth and foster a high-integrity culture that attracts, develops, and retains the best talent to deliver positive results.

Delivering Results through Operational Execution

Mackenzie Doheny

Executive Assistant and EA Coach

Mackenzie is an executive assistant (EA) with over 17 years of experience working with C-Suite executives, presidents, and founders in the non-profit, private, and public spaces. In addition, she has over 10 years of experience hiring, training, and managing administrative assistants—both to work on her team and to support other executives.

Two years ago, Mackenzie founded a virtual assistant firm that provides professional and personal assistance to owners and CEOs remotely. Due to quick success and increasing demand, she has already hired three additional virtual assistants (VA’s). As the leader of this team, Mackenzie ensures that the same level of integrity, dedication, and care given in a face-to-face environment is also given while working remotely. A thorough and fine-tuned training regimen is the key to the company’s success.

Alongside her role as the VA of the Managing Partner of CO2, she now coaches assistants on behalf of CO2, so that they are prepared for changes in work process and more responsibilities. Her coaching aligns with CO2’s values and best practices—asking questions designed to understand stakeholders’ investments and potential consequences; promoting self-awareness and a growth mindset; and acting authentically and non-judgmentally. Mackenzie believes that assistants ought to act as strategic partners with executives—providing essential front-line feedback, perceiving potential conflicts ahead of time, and making decisions that reduce workload, frustration, and confusion. Running her own company has only made Mackenzie more aware of the value assistants provide as strategic partners and front-line voices.

When she is not assisting the CO2 team, coaching EAs, or leading her company of VAs, Mackenzie can be found running, camping, swimming in the ocean or having dance parties with her two sons.

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.
