President's Address
It is indeed a great honor and privilege to be elected as a President of such prominent and established society as ASSFN. This job is particularly challenging when one has to follow stellar example of many famous functional neurosurgeons that held this post before me. Thankfully, the work of Society president is supported by the entire executive council and a cohort of Past Presidents all of whom find the time and strength in combining busy clinical and research practice with the service they provide to ASSFN. As the matter of fact, I feel that work of many past presidents and board members remains largely unknown to the members of our society and I would like to change this – first, by increasing transparency of the leadership’s activity and, second, by enlisting help from two Past Presidents, Phil Gildenberg and Roy Bakay to sum up ASSFN history in a series of personal stories and anecdotes.

ASSFN Mission Statement
The mission of the American Society for Stereotactic and Functional Neurosurgery is to foster the use of image guided and physiologically guided surgeries that alter the function of the nervous system, for treatment of neurological disorders. The Society will improve patient care, educate neurosurgeons, other physicians, allied medical specialists, and the general public, support basic and clinical research, and provide a forum at national and international meetings to fulfill these goals. Through its meetings, the Society will also establish minimum standards for the performance of stereotactic and functional neurosurgery. Read more
