I asked Mark Nevins to help with integral pieces of several strategic planning and team alignment sessions. The role that Mark played to facilitate, introduce new learnings, participate as a member of the team, and validate our direction has been invaluable. I appreciate his pragmatic approach and ability to tailor it to our needs. We took a highly fractured organization and turned it into a highly successful team in less than 18 months.

There is no better coach than Craig McCall out there who can drill down to core opportunities that translate to action plans to develop leadership skills. Craig has helped me and my leadership team immensely, and I am confident that you will see the value in his experience, expertise, and advice.

Kevin Pelletier, General Manager, Martin-Brower

Mark Nevins played a valuable, important, and constructive role in shaping our organizational structure as it evolved to fit the company’s needs and changing profile. He was instrumental in helping to identify the strengths and weaknesses of individual senior leaders. Mark also helped enormously in resolving interpersonal conflicts and in helping with the coaching of key existing and potential new senior leaders of the firm. Through these efforts, the firm has been able to adapt well to the rapidly changing environment in recent years, and in particular, we were able to navigate the dramatic effects on our business during and after the economic collapse of 2008-2009. The firm has been able to successfully implement management transitions and develop leaders who will help us grow in the future.

James Burrows, Vice Chairman and former CEO, Charles River Associates

I worked with Mark Nevins during a critical career inflection point at American Express, and to this day, I still credit him with my most profound insights and breakthroughs as a leader. One of the key things Mark taught me to do (especially in situations of conflict) was to lead through empathy: try to see the situation through the other person’s eyes, and be aware that my own rational or logical assessment of things may not be how the other person sees or interprets the situation. I have learned to adapt, ask clarifying and honest questions, be transparent and observant, and then change my lens to coach better, solve issues, and resolve conflict. Doing so has not always been easy for me, but it has led to profound enhancement of my leadership style and, I believe, helped propel me to much higher executive levels than I would have achieved if I hadn’t worked with Mark at a pivotal point in my career.

As an executive coach, Libby Halstead pushed me to define for myself the goals and objectives for the coaching and to be accountable for the pace, progress, and consistency of our work together. Therefore, I owned it, not her, which turned out to be a big part of the success. My executive coaching work with Libby represents a true turning point in my career. I had what I consider to be my most successful client engagement to date during that time (the client was not only pleased but felt we had real impact/results, and I have maintained deeper relationships with those folks than I did on previous engagements), and I also enjoyed my work more than I had before. I’ve been on a strong trajectory ever since and am in good position to get promoted this spring.

Reid Carpenter, Principal, Booz & Co.

Mark Nevins and his talented team played a critical role in helping me lead an organizational and cultural realignment during a period of explosive organic and acquired growth. Because of Mark’s strategic advice, consultation, and partnership, our firm successfully integrated five companies across three continents. And we did so while retaining key talent and clients, growing the business above industry rates, maintaining a leadership position in our space, launching new innovative technology and a new brand promise, and evolving our culture to one that brings the best of our combined companies. Mark served as a coach and advisor to me and my executive team every step of the way, and my learnings from him continue to be applied and have helped me in my ongoing development as an enterprise leader. I couldn’t have done it without Mark and his firm.

Taryn Owen, President, PeopleReady

Mark Nevins delivered a fantastic program on leading change. I felt like I was back in college again, but with lots of practical applications. We really benefited from his experience and perspectives.

Jeanmarie Alessi is a gifted leader and facilitator. I have had the pleasure to work with her for many years, and she delivers high-quality results time after time. I have engaged Jeanmarie in many capacities, which include developing manager/ leadership offerings, facilitating powerful workshops based on complex material, and to serve as a coach to help leaders develop their strengths. I highly recommend her work and have always been amazed at her ability to keep up on current research in her field of expertise—and in addition, she is just plain fun to work with!

Becky Lock, Senior Director of Learning & Development, Thomson Reuters

We had the pleasure of working with Dr. Nevins on designing and delivering a number of leadership programs for the Boeing Leadership Center. Mark is a trusted partner whose style, experience, and professionalism separate him from the pack. He is a superb lecturer and a highly ethical consultant.

Jan M. Wilmott, former Director, Boeing Leadership Center

I have initiated a number of executive offsites and retreats, and none of them was as good as the one that Mark Nevins designed and led for us. He structured the conversations well. Broke the groups up at the right moments. And most importantly he allowed the conversation to flow as it needed to. I think that the results and the insights that came out of the day were extremely helpful and constructive and I know everyone on our team felt the same way. I can honestly say Mark is the best at what he does and it was a pleasure to spend time with him.

Michael Lynton, Chairman and CEO, Sony Pictures Entertainment

Mark Nevins has conducted workshops and offsites for our team, all of which have been life-enhancing and expanding! Mark understands that the team is the most important part of any organization, and he has helped us redefine how we communicate and collaborate. When there is a high level of clarity, people thrive, and we are an even higher-functioning team as a result of working with Mark.

Honor Brodie, Creative Director, Tory Burch

Mark is able to bring theory to bear in a practical and achievable approach, and he was instrumental in helping me develop and change the culture of my firm and align my management team around a common set of values and strategic goals. In working with Mark over several years, including periods of significant change, I became a better coach and leader of my team. Mark listens well. He understands that every executive is different and adapts his approach accordingly. I found him helpful on many fronts, from the individual to the organizational level, and he helped me become a better leader while helping me align my management team.

Alain Karaoglan, COO, Voya
I cannot recommend Bill McCoy enough as an executive coach. His guidance and unwavering support have been instrumental in transforming me both personally and professionally. With his deep expertise and genuine care, Bill has helped me navigate challenges, uncover my potential, and cultivate a sense of self-belief I never thought possible. His ability to listen attentively and provide insightful perspectives has been truly invaluable. Through Bill’s coaching, I have grown into a more confident and resilient executive, equipped with the skills and mindset to overcome any obstacle. I am forever grateful for his unwavering dedication and belief in my abilities.
William Evans, Chief Risk Officer, Greenlight RE

Richard Nash is a fantastic leadership coach: he took the time to ask all the right questions and really home in on actionable steps that were digestible and tailored to my needs. Richard looks at the bigger picture yet manages to find short-term, customized goals for long-term success. He also brings a great sense of emotional intelligence and wit that I enjoyed greatly.

Amber Osborne, CMO, Doghead Simulations

In the years I have been associated with Tom Gosselin as an executive coach, I have always found him to be most receptive to my needs, whether they are on a corporate business level or on a personal basis. In business, Tom will question me to uncover what I am trying to accomplish prior to moving ahead and offering a solution. Rich in humor and anecdotes, Tom brings real business experience to his examples and applies strong principles in his actions.

Keith Slater, Head of HR for Europe, Ingersoll Rand

Since I have often been referred to as “uncoachable” over my career, Mark had his work cut out for him when he agreed to work with me. His incredible depth, caring, curiosity, and just the right amount of advice at the right time proved his mettle. Mark has been an incredible advisor and coach, and has made a huge difference to me, at work to be sure, but even in my personal interactions. Mark of course knows all of the frameworks and tools, but it’s his experience, style, and how he adapts to his clients that makes him so effective. Mark advises without judging, he carefully forces difficult conversations, and he constantly challenges me.

Joel Bines, Global Retail Co-Head, Alix Partners

Over the course of a year, Mark Nevins worked with my team at NBCUniversal, and he made a significant contribution to instilling a new mindset as we integrated sales, marketing, and editorial. He built trust across the teams and helped develop new processes to enable groups to work much more collaboratively and track positive results.

Jodi Kahn, President, iVillage
Working with Michael Palumbo was extraordinarily valuable in my first year serving at the C-suite level at the university. Michael’s probing and prompting questions led to effective self-reflection during our conversations and produced actionable strategies for me outside of our sessions. The time invested helped me accelerate my goal achievement, improve my own job satisfaction, and leverage the strengths of my team.
Romy Riddick, Vice President of Human Resources and Cabinet Member, Princeton University
