What They're Saying


  • The Carnrite Group allowed our company to extract hidden talent and knowledge from within our organization.  In doing so, they raised already high individual IQs to an even higher 'integrated' corporate IQ and enabled an empowered organization to make better decisions.

    Director – Large Independent

  • They could write an HBR article about the transformation that has taken place here.  We couldn't have done it without The Carnrite Group.

    CEO, E&P Independent

  • They're a 'one stop shop' in terms of support for our business. They are very responsive and work diligently with employees to get us ready for growth.

    President, Investment Partner

  • Carnrite's consultants challenged us, which is what we needed to get where we needed to be.

    Senior Leadership, Large E&P Independent

  • They look for opportunities to invest in the company to take advantage of mid-to-long-term opportunities, not just short term targets. They are as much advisors and partners in our business as they are investors.

    CEO, Investment Partner

  • We not only view them as investors, but also as mentors and trusted advisors. We’ve been very happy and would definitely use them again in the future.
