Superior Lawyer - Highest Integrity
Blair supported my business unit when I worked with a Fortune 100 company several years ago and more recently has worked with me as a trusted colleague, advisor and partner. Over the years, including at present, I have witnessed, first hand, his ability to devise creative legal solutions to complex legal problems as well as his ability to maintain a keen focus on solving problems, quickly and innovatively, always with his client's best interest in mind. His intellect and precise writing style benefits his clients in ways that they truly cannot fully appreciate. I recommend him unconditionally.
