John Callahan is a Vice President of Technology Services at University of Oregon Foundation. He possess expertise in networking, program management, higher education, project management, windows and 42 more skills. Colleagues describe him as "John is extremely smart, a brilliant programmer, and yet practical, not idealogical about the tools he uses. John always thinks of a better way to do something. He also has a very clear and detailed idea of what something he hasn't yet build will look like before he starts a project. It is not entirely hyperbolic to call him a genius, and I'm not the only person who thinks so." and "John made it easy for me to do my job. His prompt responses to network-related tasks meant that issues were resolved quickly. In addition to on-the-job aid, John also helped me learn. He set up a database for me to practice SQL and answered questions over email, sometimes in the evenings. There were always more things to do than people to do them at WITS, but John made me feel like my tasks were important to him."
