Specializing in UNIX® since 1982

Welcome to my web site, where you'll find descriptions of my Unix and Linux® training and support offerings. I've worked with Unix for more than twenty-five years (and Linux for fifteen) as a system administrator, programmer, and instructor. My experiences include managing networks of hundreds of heterogenous servers and workstations, and delivering hundreds of training classes covering basic and advanced Unix and Linux user skills, system administration, and Shell, Perl, and C programming.
