Pulsars are highly magnetized, rapidly rotating neutron stars that emit a beam of electromagnetic radiation that could be detected at Earth, if the emission beam is pointing toward the Earth, analogous to the way a lighthouse can be seen when the light is pointed in the direction of the observer. Pulsars within the central parsec of our Galaxy is expected to make excellent probes of not only the environment of the supermassive black hole at the center of the galaxy, but also in the case of pulsar/black hole binary systems expected in this region, of their own rich environment dominated by relativistic gravity effects. In this presentation I will give an overview of why it is important to search for pulsars in the center of the galaxy, and a summary of previous and ongoing efforts to survey this region with radio telescopes. I will describe the difficulties encountered with current surveys and prospects for detection of perhaps hundreds of pulsars in this region with new generations of radio telescopes now under construction.
