Summary
With over 24 years of experience working for City of Hope I have worked as a Desktop support team member, then moved to the Network team and finally on the Telecommunications team.
My 24 plus years working at City of Hope has gained me tribal knowledge of systems still in use at City of Hope. I have experience with the environment and the culture at City of Hope that aids me in supporting the facility and staff fast, efficiently maintaining a professional yet friendly, caring rapport with both administration and contractors.
