Peter Arnstein brings a wealth of valuable experience in corporate finance and capital markets to executive coaching for individuals, teams, and enterprises. His approach is action and outcome-oriented. Clients embrace practices that unleash their potential to get past obstacles, aim higher and surpass what they once considered not possible. The path includes identifying and clarifying goals, taking action, being accountable, and following through. Peter is known for his focused enthusiasm, insight, results orientation, and sense of humor to connect deeply and productively with clients.

Drawing upon over 30 years of investment banking experience, Peter partnered with C-suite leaders, owners, and entrepreneurs to advise on and execute strategic transactions requiring integration of a variety of subject matter and skills in a time-sensitive, high-stakes, and risk-laden environment.

Peter cultivated client relationships at Lehman Brothers and PaineWebber (now UBS) in New York, at First Union (now Wells Fargo) in Charlotte, North Carolina, and at Mesirow Financial in Chicago. He was co-head of the mezzanine investment group at GATX Capital.

Peter’s executive coaching is fueled by his interest and curiosity in developing and sustaining leadership throughout an organization and beyond. He finds executive coaching to be a tremendously challenging and fulfilling craft to continue to serve clients on a personal level with the mission of creating greater well-being for many.
