“I had much positive interaction with Dan at Citibank earlier in our careers, but my strong recommendation here is based on his executive coaching work with senior managers here at Columbia University. Dan has an uncanny ability to quickly evaluate an organization's culture at the same time he is assessing his coaching client's needs to adjust their style to improve their ability to succeed within that culture. Both his actual clients and their managers continue to praise the impact of Dan's coaching work. Whenever I am asked to refer an executive coach, Dan is the first person that I always recommend.”
