About
Data analytics and reporting leader with nine years turning ambiguous business questions into the trusted dashboards, data models, and reporting executives run the business on.
I own the full pipeline from data engineering to executive reporting, and the team that builds it — currently leading the Marketing Data & Analytics function at Trane Technologies, where our dashboard portfolio is the single source of truth on marketing performance for 600+ stakeholders across 10+ departments.
Background
I was born in Chicago and raised in the suburbs. I attended Drake University in Des Moines, Iowa. I now live in Charlotte, North Carolina, with my wife Karly — together since 2018 — and have worked at three companies since graduating.

Senior Marketing Data Visualization Manager
Marketing Strategy & Operations Center of Excellence, realigned in 2025 into a dedicated Marketing Data & Analytics function.
- Own the executive dashboard portfolio for the company's two largest business units, the single source of truth on marketing performance for 600+ stakeholders across 10+ departments, directly informing how $100M+ in annual marketing spend is allocated.
- Directly mentor and develop three analysts, growing the team's autonomy to independently deliver five dashboards and six dataflows built on that coaching.

- Lifted core data quality, filtering 8% bot traffic out of web analytics and correcting geographic attribution on 15% of leads, cutting reporting wait times 50% by moving error handling from weekly to daily checks.
