Soren's executive guidance and advice have been invaluable to lynda.com 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!
