Robertson credits extraordinary SMPH faculty mentors — including Paul Carbone, MD, and Dennis Maki, MD ’67 — with helping guide decisions about his postgraduate training. He matched to University of California, San Francisco, for an internal medicine residency and switched to an anesthesiology residency.
While in his first clinical position at the Anesthesia Service Medical Group in San Diego, Robertson earned a master of business administration degree and expanded the practice. The degree served him well.
A former crew teammate recruited Robertson into a leadership role at the Milwaukee-based Marquette Medical Systems, a diagnostic cardiology company. He and his wife relished their move — despite a 100-degree temperature difference in January 1983 — because they wanted to raise their three children near their extended families.
Marquette Medical Systems was later purchased by GE Medical Systems, with Robertson continuing to lead, eventually becoming its chief clinical officer. (GE Medical Systems became GE Healthcare after Robertson left the company.)
In 1993, Robertson joined the Medical College of Wisconsin faculty and completed a pediatric anesthesiology fellowship at Children’s Hospital of Wisconsin. There, he practiced in that field, taught residents, and conducted clinical research.
Next, T. Rockwell (Rock) Mackie, PhD, an SMPH emeritus faculty member and co-founder of Tomotherapy, recruited Robertson to join that company. The start-up was in the early stages of commercializing its image-guided, intensity-modulated radiation therapy that targets tumors while minimizing exposure to neighboring tissues.
“Although I had not planned to re-enter the business world, this was a compelling opportunity and provided a chance to move back to Madison — a great place to live,” says Robertson, who served from 2005 to 2011 as Tomotherapy’s CEO and president of its board of directors as he helped the multi-million-dollar business become a public corporation. “It was both an exciting and turbulent time.” During that time, Robertson also lost his wife following a 10-year battle with Alzheimer’s disease.
In 2011, Accuray purchased Tomotherapy, and soon after, Robertson became an assistant professor in the SMPH Department of Anesthesiology. For about six years, he taught medical students and residents and practiced anesthesiology at UW Hospitals and Clinics.
Since his 2018 retirement, Robertson has worked with several early-stage health care companies as an advisor and/or board member. Among them is Ensodata, an artificial intelligence company related to sleep apnea, founded by a former UW–Madison biomedical engineering student for whom Robertson had been a mentor.
Now serving on UW–Madison’s Morgridge Institute for Research Board of Trustees, he is a venture partner for Baird Capital, a financial services firm in Chicago. Having remarried, Robertson and his wife also stay busy with their extended family and occasional travels.
When speaking to SMPH students, Robertson describes the ways in which he has leveraged his clinical and business backgrounds.
“I love to see other people succeed, and I am excited about the way technological advances can improve patient outcomes,” he notes. “What I learned at the UW School of Medicine and Public Health and in postgraduate training prepared me well clinically and has had a huge impact on my business-related ventures.”
He concludes, “Successful entrepreneurs surround themselves with talented people. I’ve been very fortunate in this way.”
