“I would like to thank you for the work you have done to keep this group together throughout an extremely difficult year. Your pivot to biweekly meetings and the sharing of relevant information was a tremendous help to me and I’m sure everyone in the forum. There were many times I was near the brink of giving up but those meetings always gave me inspiration. As the saying goes “if you’re going through hell, keep on going! We’re near the end of the year and it’s hard to believe we’re somewhat busy, especially the book business, and able to pay above average bonuses to our production team for all their sacrifices. It’s a reflection of the support I feel I get from you all!”

“Marc has the ability to uncover issues and identify needs without “pulling a fire alarm.” He assists with the issue and continues to ask questions and point to potential solutions or options.One year after we followed Marc’s advice and hired a strong bookkeeper, our EBITDA was more than three times greater than the previous year.”

“I have had the opportunity to work with Marc and build a solid friendship over the years. His great ability to listen coupled with his diverse business experience helps many executives navigate the business climate to success. Several times, I can recall Marc’s advice helped through some difficult situations. I refer to Marc as the professional guide for owners as they journey through growing a company. I highly recommend Marc, as someone you want to know both professionally and personally.”

“Although I benefited as a member of TAB, my experience in the Entrepreneurs Council has been overwhelmingly more positive. The members are more dynamic, more resourceful, and there is a broader spectrum of businesses represented. Perhaps in part because the Entrepreneurs Council is not a franchise, Marc Sinkow attends to sustaining the group more effectively, which may explain the lower turnover I’ve observed. Most importantly, Marc is an agile leader who has more extensive business experience. The meetings are more enjoyable, and I am paying a lesser fee for what I see as a greater value.”

“I have known Marc Sinkow for quite a few years now, and, over that time, have collaborated with him in a number of different capacities. My universal conclusion from all of those interactions is that Marc is a high performer, whether in a role leading an entire business, in business development and growth strategy, or acting in the capacity of advisor or coach to other business leaders.

Marc is an insightful and highly ethical person with a proven track record of success and a good friend as well. As such, I recommend him highly.”

“I have known and worked with Marc for almost four years. His business acumen and his people connections have been quite valuable in helping us to grow our business.

As a business coach, he is an excellent motivator who clearly listens to what I have to say and when necessary, Marc has guided me in the right direction.
