M. Gregg Roe grew up in central Ohio, and attended the rather large university based there. He lived and worked for a time in Virginia and California before finally taking up residence in Tennessee.

Gregg has a Ph.D. in physics, which helps not at all when writing fantasy novels. His leisure activities include cycling, anime, travel, reading (primarily fantasy and hard science fiction). He also enjoys playing Dungeons & Dragons, and his fantasy novels are based after the campaign he started in 1979 and which is still running.
