Our Team at Morgan Stanley Green Bay Branch

About John Bull

As Branch Manager, I take pride in my commitment to being an advocate for my Financial Advisors. My priority is coaching, developing and influencing the behavior of the Advisors I serve in order to help them leverage and improve their skills, build meaningful client relationships, and help successfully run their businesses. As a dedicated coach, my approach is built on an unwavering focus on individual skill development through open communication and honest feedback. I strive to enhance partnerships across business lines with a relentless commitment to thinking outside the box to help find more effective strategies.

I am proud to be working with a group of Advisors that seek to align beliefs in providing advice and guidance to clients throughout life’s financial opportunities and turning points.

My personal mindset is to always be working to help improve your situation, and I extend that to my team of Advisors. I am energized by the opportunity to help them challenge the status quo and discover new, innovative strategies that seek to address problems that range from the common to the complex. I highly value the personal connections I forge with my team, supporting and interacting with them, aligning their business goals with what’s most important in their lives, and helping them do what they do best every day.

A Minnesota native, I am in the midst of a transition to Green Bay with my wife, Hannah, and our two sons. My spare time is focused on my two passions: family and the outdoors. My wife and I stay active with the kids, riding bikes, hiking and spending time together. I love being outside and enjoy boating, fishing and chasing waterfowl.

6The returns on a portfolio consisting primarily of sustainable investments may be lower or higher than a portfolio that is more diversified or where decisions are based solely on investment considerations. Because sustainability criteria exclude some investments, investors may not be able to take advantage of the same opportunities or market trends as investors that do not use such criteria.
