Leadership

Technical Knowledge Meets Business Leadership

Technology only creates value when people understand it, trust it and know how to use it.

I am comfortable working with data engineers, analysts and developers, but I am equally comfortable sitting with executives, clinicians, operations leaders, clients and other nontechnical stakeholders.

I translate complex analytical and technical information into clear business language, present findings to leadership, facilitate requirements discussions, challenge assumptions when necessary and help teams move from information to action.

My leadership style is collaborative, accountable and solutions-focused.

My technology experience also extends beyond analytics.

I have designed websites, digital platforms and software experiences with an emphasis on both visual presentation and business functionality.

I approach web and product design by asking the same questions I ask in analytics: Who is the user? What are they trying to accomplish? What process can be simplified? What information matters most? And what should happen next?

My goal is not simply to make technology look good. It should make the business work better.
