Soren Eilertsen is a world class mentor and leader. His vast business experience and grasp of my business challenges have had immeasurable impact, and his personal guidance has enabled me to grow as a leader.

Jim Kirkland
Director of Service, American Suzuki Motor Corporation 

Soren's executive guidance and advice have been invaluable to and me personally over the past years. He has a remarkable ability to step into difficult situations as well as step up to take on interim leadership in critical areas of the organization. As an example, he oversaw one of the most successful acquisitions and integrations that I have ever seen. I couldn't have done it without him!
