About

I am a highly experienced IT Support Specialist and Service Desk Manager with a career focus on great customer service (recognized with numerous company awards throughout my career), process improvement, team development, and device management. For the last 7 years I have worked extensively with MDM via MS Intune and JAMF, administering policies, compliance, security remediations, and software packaging. In my time on the Amazon Helpdesk I planned and implemented the training of a new Tier1 Helpdesk team of 12 customer service associates so they could begin taking Helpdesk phone calls. I then mentored that team and provided additional training as the role of the Tier 1 team was expanded. In my last role at Xperi I managed a global service desk with teams in the US, EU, and Asia. We maintained high level (90%+) SLAs for speed of contact and first contact resolution, while also working on skill development with all three teams. This eventually resulted in the Asia team taking on the Software Packaging for Intune. This same team also succeeded in converting all Windows 10 systems to Windows 11 in 2025 prior to the end date, while also supporting a migration from Zoom and Slack to MS Teams. Also at Xperi, I was a key member of the team that developed and deployed an automated process for the creation, management, and eventual deactivation of all employee and contractor accounts in Active Directory. Data synced from ADP to ServiceNow and then to Active Directory and accounts were updated throughout their lifecycle. Throughout my nearly 30 year career I have also picked up experience with C-Level Executive support (and Executive Admin support), corporate event planning and production, software administration (AD, M365, Okta, Google Suite, Adobe, Smartsheet, etc), Atlassian products (specifically Confluence an JIRA), software development with Agile, shell scripting, video conferencing, as well as remote management and support. I truly enjoy helping to ensure corporate users are able to accomplish their jobs with high quality support from IT, as well as finding IT solutions to complex problems that benefit our corporate customers. I hope we get to work together sometime soon.
