=================		 I’m a seasoned Senior IT Support Manager and Cloud Support Engineer with a knack for turning complex tech headaches into smooth, user-friendly solutions. With over 15 years of experience keeping systems (and people) up and running, I’ve mastered the art of troubleshooting, cloud management, and making “Have you tried turning it off and on again?” sound like the start of a rescue mission. Whether it’s deploying cloud solutions, leading high-performing support teams, or just geeking out over the latest tech trends, I bring energy, expertise, and a good sense of humor to every project. I’m passionate about delivering top-tier support while making tech approachable, efficient, and—dare I say—fun.
Work Experience
Regional Support Manager

Global Service Delivery, Arthur J. Gallagher & Co.

  • Provided primary lead support for the Tulsa–Oklahoma City region, proudly wearing many hats (sometimes all at once).
  • Masterfully coordinated team workflows—juggling priorities, delegating duties, and occasionally reminding everyone that coffee is not a substitute for a plan.
  • Conducted SOX audits, submitted annual IT budgets, and kept the office fully stocked with shiny new IT equipment (you’re welcome).
  • Assisted in deploying desktops, servers, Cisco gear, MPLS networks, and provided top-tier end-user support—because sometimes turning it off and on again really is the solution.
  • Served as Change Coordinator for BSD South Central and Central regions, managing changes with the precision of a cat walking across a keyboard (but with much better outcomes).
  • Acted as the key escalation point for all customer issues, translating tech jargon into human when needed.
  • Reviewed and verified third-party and external costs with the Controller, because numbers deserve just as much attention as networks.
  • Maintained and updated site information in MS SharePoint, ensuring it didn’t become the forgotten attic of outdated files.
  • Kept users and management in the loop on customer-related changes—no surprises on my watch.
  • Bridged the gap between clients, vendors, business units, and Global Technology Services, making sure everyone spoke the same language (or at least pretended to).
Windows 7 Deployment Engineer

Conoco Phillips/Prosource.

  • Collaborated with a dedicated team to successfully migrate over 200,000 users from Windows XP to Windows 7—proving large-scale upgrades can happen with minimal tears and only a few stubborn printers.
