Tim retired as a player in 1986 and became a highly regarded coach for leading tennis players, including Aaron Krickstein, Mary Joe Fernandez, and Martina Navratilova. His most notable coaching success was with Pete Sampras, regarded by many as one of the greatest players of all time, whom Tim coached to the No.1 world ranking in 1993.In 1995 Tim was diagnosed with brain tumors. In battling his cancer, Tim and his family recognized a critical need for helping brain tumor patients and their families in managing the physic at emotional and social challenges of the illness. In order to fulfill that need, Tim and Tom Gullikson, along with their families, founded the Tim & Tom Gullikson Foundation (TTGF) in 1995. A year later, Tim lost his battle with brain cancer, but his vision for the Tim & Tom Gullikson Foundation flourished. With support from the tennis community, business leaders, and concerned individuals, TTGF raised more than $6 million over the years to advocate for cancer patients and their caregivers. In 2008, the TTGF transferred its remaining funds to the Pediatric Brain Tumor Foundation to establish the Tim & Tom Gullikson Family Support Fund, which funds college scholarships for children affected by brain tumors.
