Board of Directors


Susan Slocum
Chair of the Board

Susan Slocum currently manages $2.1 billion in assets for Children’s Minnesota and an additional $2.6 billion in related ERISA funds.  As an active allocator, Ms. Slocum’s approach for Children’s Minnesota is to optimize returns commensurate with the organization’s risk tolerance.   

Within the private market allocation of the portfolio, Ms. Slocum has segregated and developed a Strategic Healthcare Impact Portfolio that is composed of select fund managers and direct investments that target or can pivot to improving child health.  Collaborating with Children’s internal researchers and subject matter experts, she seeks to improve both Children’s view of innovative science and fund managers’ view of practical use.

Currently, Ms. Slocum is working on how Children’s portfolio is advocating across the diversity, equity, and inclusion landscape.  She has actively rebalanced the public equity exposure across sectors to move the public market funds managed by firms that advocate for women and people of color up from the previous 31% to over 60% while improving the risk/return profile of the portfolio.

Stuart Winter

Since joining Children’s Minnesota as its Chief Research Officer in 2017, my focus has been to promote and support the institution’s 12 research departments.  Beyond the traditional goal of utilizing research to advance discovery and innovation, Children’s Minnesota has aligned its research efforts to advance value-based care, quality/safety, and equity/inclusion to the benefit of all Minnesota children and their families. I manage the creation and implementation of basic and applied research projects, the evaluation and development of new processes, technologies or products, and partnerships with surrounding academic institutions. As an affiliate Professor of Pediatrics at the University of Minnesota, I co-chair the Child Health Advisory Committee with Dr. Mark Schleiss. The charter of this effort is to understand and mitigate social determinants of child health.

With certification by the American Board of Pediatrics in Hematology/Oncology from 1994 onward, I have three decades of experience as a practicing clinician-scientist. My translational focus is primarily directed towards the biology and classification of acute lymphoblastic leukemia (ALL) and the conduct of pediatric clinical trials. I have experience in managing pre-clinical trials, including those that involve testing new agents (biologics) in animal models.  As a former IRB chair and treating physician, I have experience in all phases of clinical trial design and implementation, including the steps that involve regulatory agencies (e.g. the FDA, CTEP, NIH, PedCIRB) as well as pharmaceutical companies.
