Columbia was a valuable partner for Adjoined and especially for me personally. Their broad experience with start up organizations was extremely helpful in the early days of establishing Adjoined. As the business matured, Columbia was a patient and insightful contributor to the Board of Directors and played a valuable role among the senior leadership of our organization. They were the right partner for us every step of the way."
