January 23, 2025

Pine Tree Apple Classic Fund President Kevin Werwie and its Board of Directors have announced the hiring of Lisa Mushett as the organization’s first-ever Executive Director after serving as the Event Coordinator of the Pine Tree Apple Tennis Classic since 2020. In her new role, Mushett will play a pivotal part in driving the company’s strategic initiatives and fostering continued growth while still overseeing the Pine Tree Apple Tennis Classic - and its 40th Anniversary celebration - set for July 31-August 3, 2025, at Life Time White Bear Lake in White Bear Lake, Minn. 


“We are so honored to have Lisa as not only our first Executive Director, but our first employee of the Pine Tree Apple Classic Fund,” Werwie said. “Our success over the past 39 years has been based on the tremendous generosity of so many sponsors, donors, players, volunteers and the Children’s Minnesota research team and staff. We have grown to a point where an Executive Director is critical to ensure our continued success. Lisa brings a wealth of professional experience, leadership skills, tennis connections and a team-first approach that makes her a perfect fit for this position. She is passionate about our mission to help these kids impacted by cancer, and I have no doubt that she will continue to lead us successfully for many years to come.”


Mushett brings a proven track record in the marketing, communications and tennis industries to her new position. Since her arrival in 2020, the Pine Tree Apple Tennis Classic and Pine Tree Apple Classic Fund have experienced substantial growth both on and off the court. The tournament has grossed over $2 million during her time, with approximately $1.6 million gifted to Children’s Minnesota for targeted pediatric cancer and research initiatives. The tournament has also expanded its tennis draws in the Masters and Grand Masters Division and has brought back a Junior Division featuring many of the top junior players in Minnesota. The Pine Tree Apple Classic Fund has also established two endowments at Children’s Minnesota including the Pine Tree Apple Tennis Classic Endowed Chair in Cancer and Blood Disorders Research in 2020, and the Hematology, Oncology Point of Care through Survivorship Research Endowment Fund in 2024. 


Prior to her work with the Pine Tree Apple Tennis Classic, Mushett served as the Director of Marketing and Communications for the United States Tennis Association Northern for 15 years and coordinated many of its special events including the Aquatennial Tennis Classic, the Women’s $50K Pro Circuit tournament, the Tennis Festival of the North and the annual Hall of Fame and Awards ceremonies. She is also one of the top junior and college tennis officials in the country, currently serving as the Supervisor of Tennis Officials for both the Big Ten and Minnesota Intercollegiate Athletic Conferences and is a member of the Intercollegiate Tennis Association’s National Officials Committee..


“I am incredibly honored and humbled to be named Pine Tree Apple Classic Fund’s first Executive Director,” Mushett said. “What started as a local community event made up exclusively of volunteers 40 years ago has grown into an impactful Minnesota 501(c)(3) non-profit organization that is truly saving the lives of children locally and around the world … and we are only getting started. I look forward to continuing my work with the Pine Tree family in this new role as we continue to expand and grow in hopes of one day saying ‘Game, Set, Cure!’”

Children’s Minnesota is pleased to announce the selection of Dr. Kris Ann Schultz Pine Tree Apple Tennis Classic Endowed Chair of Blood and Cancer Disorders Research as its new chief research officer at Children’s Minnesota. “I’m grateful to have Dr. Schultz step into this important role. Her leadership will help us advance our mission of developing a premier pediatric research institute and improving access to cutting edge research for our patients and families,” said Dr. Anupam Kharbanda, vice president and chief of clinical innovation. “Dr. Schultz has been a driving force in pediatric research both internationally and in our community, and I’m excited to see how she’ll build on our legacy and lead our team”. Dr. Schultz has been a pediatric oncologist at Children’s Minnesota since 2008. Prior to taking on the role of chief research officer, she served as scientific director of the Cancer and Blood Disorders program. In her 17 years of service at Children’s Minnesota, Dr. Schultz has made significant contributions to pediatric oncology care and research, serving as principal investigator for the International Pleuropulmonary Blastoma (PPB)/DICER1 Registry which includes participants from more than 600 institutions in 60 countries worldwide. In 2020, Dr. Schultz was named the inaugural Pine Tree Apple Tennis Classic Endowed Chair in Cancer and Blood Disorders research. Dr. Schultz is considered one of the foremost experts on DICER1 research and has published more than 100 peer reviewed articles including first author publications in the Journal of Clinical Oncology and Clinical Cancer Research. Her research focuses on the early detection and the development of novel and precision therapies for DICER1-related cancers. In 2017, Dr. Schultz and the Registry team published the first-ever set of surveillance guidelines for individuals at risk for DICER1-related tumors. In 2025, Dr. Schultz and the Registry team published updated guidelines based on ongoing data collection and assembly of the world’s largest cohort of individuals with DICER1 variation. She serves as Study Chair for Children’s Oncology Group protocol ARAR2331, the first ever prospective clinical trial for pleuropulmonary blastoma, the most common form of lung cancer in infants and young children. She also serves as Vice Chair for rare tumors for Children’s Oncology Group, an international cooperative group focused on pediatric cancer which includes more than 220 institutions worldwide. Dr. Schultz is also the founder and serves as the principal investigator of the International Ovarian and Testicular Stromal Tumor (OTST) Registry. As a result of Dr. Schultz’s contributions, Children’s Minnesota has achieved international recognition for its collaborative research on rare tumors and early detection. This work has contributed to higher survival rates and improved quality of life for children with cancer around the world. Importantly, these research developments are shared not only with clinicians and researchers, but also directly with patients, families and research participants through family education documents, newsletters, and an annual scientific symposium and family meeting attended by participants from across the world. “This work is inspired by the kids and families we serve. Our research strength comes from the generous contributions of our many research participants and the multidisciplinary teams of kid experts working side‑by‑side, focusing on the health needs of kids and families,” said Dr. Schultz. “I am honored to work with these amazing individuals and look forward to connecting ideas, removing barriers, and accelerating studies so the benefits of our research reach more kids and families in Minnesota and worldwide.” In her role as chief research officer, she will provide guidance and support to the Children’s Minnesota Research Institute , which is dedicated to advancing research and innovation that directly impacts patient care. She will oversee multidisciplinary teams’ leading efforts in cancer and blood disorder research, cardiovascular research, diabetes and endocrine research. With a focus on improving the daily lives of children and teens, Dr. Schultz and her team will continue to champion initiatives ranging from innovative pain management strategies to the adoption of cutting-edge technologies—ensuring that all research remains centered on the needs of kids and families.
