We are fortunate to have someone with Misha’s experience and skill in this role, guiding our high ethical standards and approach to complex legal issues.’

In a very short time, he demonstrated exceptional judgment and built trust across all levels of our organization. Misha brings valuable public and private experience to our team and I look forward to working closely with him in this important leadership role.’
