Executive Coach
Business Partner

Elaine is more than a coach; she is a great business partner. I have worked with Elaine over the course of two years. Elaine brings espirit de corps to her professional engagement through candor, holistic thinking, and a high level of professional experience in navigating the nuisance of leadership development. She was helpful not only in developing the high-level strategy, but also in developing the tactical details of the execution plan. My team benefited greatly as Elaine was able to help them develop awareness of blind spots, and coached them effectively to reduce and manage their vulnerabilities.
