Managing engineering projects involves managing technical decisions, people, and risk. Engineering managers also have to communicate clearly with vendors, other departments and customers,  A manager will be better prepared to perform these diverse tasks if he has both machine design and management experience.   My experience managing engineering groups  in both California and Kansas has included projects involving teams in different states and sometimes in different countries.  If you need an engineering manager to fill a temporary void or allow you to pursue new projects, I have the experience to fill that role.
