About Corwin B. Marbly Jr.

Mr. Marbly is an investment professional at William Blair & Co. LLC, where he has provided client-focused financial services since 2016. He specializes in creating strategies for high-net-worth individuals and families, ensuring that each client receives thoughtful guidance and transparent communication. His dedication to excellence was recognized in 2023 when he received the John P. Nicholas Award from the William Blair Nicholas Award Committee.

Before joining William Blair & Co., Mr. Marbly developed deep industry experience in key financial roles. From 2009 to 2016, he worked as a wealth management adviser and client associate at Wells Fargo Private Bank, serving ultra-high-net-worth individuals, including billionaire families. Earlier, he refined his skills in mergers and acquisitions as a senior administrative assistant with Houlihan Lokey, where he gained valuable insight into distressed properties and corporate transactions. His early career included real estate management at Heitman and work with brokerage firms, where he first observed how financial structures create wealth and stability.

Mr. Marbly's passion for finance began after high school when he entered the workforce instead of immediately pursuing college. Early exposure to successful investors inspired him to learn how financial systems operate and motivated him to build a career that combined professional achievement with personal purpose. After serving as a staff sergeant in the U.S. Army from 1991 to 1997, he used the discipline and leadership skills he acquired in the military to guide his academic and professional pursuits. He soon earned an associate degree in business with a focus on corporate communications from Olive-Harvey College in 1997, where he was inducted into the National Honor Society. He also earned a bachelor's degree in business administration, management and operations from the University of Illinois at Chicago in 1998, graduating cum laude.

A Commitment to Career, Mentorship and Service

Beyond his professional accomplishments, Mr. Marbly remains deeply committed to mentorship and service. He frequently meets with young professionals to share his story and provide guidance on building successful careers in finance. He serves on the executive leadership council for Stop Soldier Suicide and is a member of Project Healing Heroes. He also co-chaired the William Blair Veterans Alliance and serves on the boards of both the William Blair Alliance Group and the Bozzuto Resident Advisory Panel.

Mr. Marbly's career achievements have earned widespread recognition. In addition to the prestigious John P. Nicholas Award, he has been honored by the National Honor Society and the National Society of High School Scholars. Looking ahead, he plans to expand his client base and continue mentoring the next generation of financial leaders. His goal is to ensure they gain the confidence and knowledge to reach their own goals.
