Steve E. Titus, M.A., R.P.A., President/Principal Investigator

Steve Titus is the owner and President of ARG. He received his B.S. in Elementary Education from Southern Illinois University Carbondale in 1978 and his M.A. in Anthropology (Archaeology) from Southern Illinois University Carbondale in 1993. Steve is a registered professional archaeologist (RPA) with 33 years of experience in all phases of archaeological investigations in the Midwest and the Plains, including prehistoric and historic field research and report preparation. His responsibilities include writing proposals, formulating and implementing research designs for testing and mitigation projects, directing field investigations, preparing technical reports, and editing finished reports for content. His research interests include prehistoric settlement patterns, chert-type sourcing, and lithic technology.

Following a brief career working in a social services agency with disadvantaged youth and as a teacher in an alternative school and a migrant farmworkers’ camp, Steve’s lifelong interest in archaeology and American history was rekindled by a summer spent working as a Forest Service volunteer conducting backcountry surveys in the National Forest surrounding Yellowstone National Park. This experience, appealing, as it did, to both his love of the outdoors and his intellectual curiosity, led him to return to school to retool as an archaeologist, a career path he has now been following for more than 30 years. In addition to spending time with his son, sisters, nieces, and nephews, Steve enjoys traveling, hiking, visiting Civil War battlefields, flint knapping, and reading.
