I am a partner at McKinsey & Company, based in New York. As the core leader of McKinsey’s Strategy and Corporate Finance practice, I advise and serve clients on topics such as: value creation, corporate strategy, investor relations, dividend/share repurchase policy and mergers and acquisitions (M&A).

My passion is helping companies become more long-term oriented in their value creation approach. Consistent with that passion, I have co-authored the books, Valuation: Measuring and Managing the Value of Companies (the 7th edition will be published in May 2020) and Value: The Four Cornerstones of Corporate Finance.

I founded our firm’s hub for financial and capital markets analysis and valuation, and also founded McKinsey on Finance, our firm’s quarterly corporate finance publication. I frequently lecture on finance topics at business schools including Chicago Booth, Northwestern, Tuck, Columbia, and INSEAD.
