Peter Geyser has vast experience in the rapidly evolving field of consumer electronics and information technology. He strongly believes that technology should not be an impenetrable maze in which only a select few possess the knowledge to navigate its murkiness. Rather, technology should be intuitive, democratic, and transparent.

Starting as a technician and moving into a management and administrative role, Geyser has gained insight into the varied needs of the many users of tech. Working with individuals and businesses alike, he has been able to draw upon his breadth of knowledge to make concrete suggestions on how technology can be used in a more natural and efficient way. He brings with him a vision that technology usage in a business setting should be as straightforward and reflexive as it is in our daily personal lives.
