    I've been an IT professional for 25+ years. For the majority of my corporate career I was a one man IT department for a regional property management firm. I managed all aspects of corporate IT including server administration, desktop support, and cybersecurity strategy. Since 2016 I've specialized in Google Workspace administration and am a certified Google Workspace administrator. My largest Google Workspace deployment was over a thousand users and have managed deployments as small as a single user. I have the breadth of knowledge needed to assist your business in maximizing the return from your IT investment. I'm a big believer in the opportunities that automation offers small businesses. I can assist you in streamlining and simplifying repetitive tasks so they're done correctly every single time with very little effort. I have a teaching mindset and am comfortable assisting non-technical users, so if you just want to get something done without all the jargon, I'm happy to do that. Alternatively if you'd like to go into all the details about a topic I'll take you there as well.
